“There is no scientific evidence that food or other
nutritional essentials are of any specific value in the control of cancer.”
AMA Declaration, 1949
“We must act on facts, and on the most accurate interpretation of them,
using the best scientific information. That does not mean we must sit back
until we have 100% evidence about everything. Where the state of the health of
the people is at stake, the risks can be so high and the costs of corrective
action so great, that prevention is better than cure. We must analyze
the possible benefits and costs of action and inaction. Where there are
significant risks of damage to the public health, we should be prepared to take
action to diminish those risks even when the scientific knowledge is not
conclusive, if the balance of likely costs and benefits justifies it.”
Richard Horton, Editor in chief, Lancet, July 1988
Prevention is the most important and most reliable cancer-fighting tool available. There is, indeed, much we can do to prevent this dreaded disease. Cancer prevention means preventing a first cancer episode and/or preventing a recurrence after successful treatment of a cancer. Creating and maintaining a healthy and strong immune system is the cornerstone to cancer prevention and treatment. Such measures that accomplish this effort include:
·
Diet and
Nutrition
·
Exercise
·
Maintaining
a Healthy Weight
·
Avoidance
of Chemical Toxins and Radiation in the Home and the Environment
· Stress Reduction and Building Emotional/Spiritual Health
American Cancer Society
Guidelines for Cancer Prevention
We will begin our discussion of cancer prevent with the American Cancer Society (ASC) 1996 Advisory Committee’s Guidelines on diet, nutrition, and cancer prevention with healthy food choices and physical activity. The ACS guidelines are very conservative as they choose to wait for long-term definitive studies proving or disproving many recommendations for cancer prevention. Such course of action will take years and probably decades before those answers are found. Consequently, we have chosen to editorialize the ACS guidelines based on our opinions of the scientific literature on cancer prevention and immune system augmentation. You may then choose which and how many recommendations you want to incorporate into your health maintenance and cancer prevention program.
The ACS affirms (are we whole heartedly agree) that dietary practices and physical exercise along with smoking cessation, avoidance of occupational cancer causing substances and early detection are important factors in the prevention of cancer and cancer death. The details of their recommendations are as follows:
·
Choose
most of the foods you eat from plant sources
Ø Eat five or more servings of vegetable and fruits each day.
Ø Include vegetables in every meal and choose fruits and vegetables for snacks.
Ø Include grain products as whole grains instead of processed (white) grains
Ø Choose beans as an alternative to meat
The evidence of eating increased vegetables and fruits to reduce the risks of colon cancer is strong. Evidence is present, but less strong for such cancers as breast and prostate.
· Limit your intake of high fat foods, particularly from animal sources.
Ø Replace fat rich foods with fruits, vegetables, grains and beans
Ø Eat smaller portions of the high fat foods
Ø Choose baked and broiled foods instead of fried foods
Ø Select non fat and low fat milk and dairy products
Ø Select lean cuts of meat
Ø Eat smaller portions of meats
Ø Choose beans, seafood, and poultry as an alternative to beef, pork and lamb
Ø Select baked and broiled meats, seafood and poultry, rather than fried
High fat diets have been associated with an increase in the risk of cancers of the colon, rectum, prostate, breast and uterus.
· Be physically active, achieve and maintain a healthy weight.
Ø Be at least moderately active for 30 minutes or more on most days of the week.
Exercise has been shown to reduce the risks of colon, rectum, prostate, uterus, breast and kidney cancers.
· Limit consumption of alcoholic beverages, if you drink at all.
Cancer rates start to rise with as few as two drinks per day. Alcohol consumption is associated with cancers of the mouth, esophagus, and breast.
The above guidelines are the general recommendations of the American Cancer Society. We will now explore them in more detail with extended information and recommendations.
Diet and
Nutrition
With up to 60% of all cancers being related to dietary factors, diet and nutrition are perhaps the most important aspects of any cancer prevention program. The dietary habits to protect yourself from cancer involves eating a food diverse diet that maintains normal weight, reduces or eliminates carcinogenic (cancer causing) and hormone containing foods and increases the amount of protective nutrients you eat. You should be able to meet these goals with a diet emphasizing vegetables and organic foods.
These dietary principles of cancer prevention are built into the recommendations of the Basic Health Maintenance Diet as listed in the book It’s Only Natural, by Drs. Poesnecker, Buttram and Kracht and our separate handout with the same title. We strongly encourage you to use this extensive resource to help you meet the cancer prevention goals of reducing your exposure to contaminants and increasing your body’s ability to protect itself from cancer and other diseases. Furthermore, extensive and extremely helpful dietary and nutritional information may be found in the book Beating Cancer With Nutrition, by Patrick Quillin, PhD, R.D.
Foods with Protective Nutrients
The American Cancer Society states that nutrients and nutritional factors in the diet can protect the DNA from being damaged and can delay or prevent the development of cancer. There are now over 200 studies showing that a diet rich in fresh vegetables and fruits can substantially lower the risk for various types of cancer (so much for the AMA declaration if 1949!). When ever possible, include the following cancer protective foods and nutrients into your diet as much as taste and individual food intolerances permit:
· VEGETABLES, VEGETABLES, VEGETABLES, and more VEGETABLES- they contain the antioxidants and minerals that protect the cells from damage and cancer development.
· Carotenoids- are antioxidant compounds that make vegetables and fruits orange or yellow color. They function as “antioxidants” which protect the cells from “free radical” damage caused by chemicals and other substances. Names of specific carotenoids include alpha and beta carotene, cryptoxanthin, zeaxsanthi, lutein and lycopene. Studies have shown that eating whole foods rich in these substances can reduce the risk of cancer. Men whose diets are high in tomato products (which contain the compound called lycopene) have a lower incidence of prostate cancer (Am J Epidemiology, Vol 133, 1991). There have been several studies demonstrating that beta-carotene supplementation by itself actually increased the risk of cancer in smokers. However, when taken in whole food as a balanced with other antioxidant, beta carotene is cancer protective. Foods high in Alpha and beta carotene include carrot, sweet potato, pumpkin, winter squash, yams, cantaloupe, beans, broccoli, Brussels sprouts, algae, spinach and other green leafy vegetables; Cryptoxanthin foods include oranges, grapes, lemons, tangerines, apples, corn, and poultry. Zeaxanthin foods include peaches and corn. Canthaxanthin foods include trout, crustaceans and mushrooms. Lutein foods include kale and spinach. Lycopene foods include tomato, watermelon, guava, and grapefruit.
Broccoli & Tomatoes Together: Researchers from the University of Illinois at Urbana have determined that eating broccoli and tomatoes together may offer better protection against prostate cancer than eating either vegetable alone, reports Reuters. Why? Mixing the compounds from the two foods could have a synergistic effect. The study, which was done in rats, looked at the effect of these two foods as a unit. Previous research has found that each of them separately offer protection against cancer. For tomatoes, the lycopene--that's what makes them red--is likely the magic ingredient. For broccoli, it's a compound called glucosinolates.
The study: Four groups of rats were injected with human prostate tumors that mimic human cancer to a certain degree (although not perfectly). Each of the rat groups were fed one of the following: dried, powdered tomato; dried broccoli; a combination of both; or a drug called finasteride that has been shown to reduce the benign growth of the prostate. The results: All the rats developed prostate cancer tumors, but the tumors grew more slowly and stayed smaller in the three groups of rats that had been given the food supplements. The rats given both broccoli and tomato had the smallest tumors, notes Reuters. "Separately, these two foods appear to have enormous cancer-fighting potential. Together, they bring out the best in each other and maximize the cancer-fighting effect," Erdman said. Journal of Nutrition
Flavonoids- flavonoids are a class of nutrients that act as specific antioxidants and help the body to optimize its use of vitamin C. These two cancer protective nutrients often coexist in fruits and vegetables.
· The citrus bioflavonoids hesperitin in oranges and naringenin in grapefruit inhibit breast cancer cells in a test tube (Nutrition and Cancer, Vol 26, 1996).
· The bioflavonoids called Anthocyanins are found in berries and grapes. Research shows that berries are among the fruits highest in antioxidant content and that they are excellent sources of several phytochemicals that seem to help block cancer development. In laboratory test tube studies, anthocyanins inhibit growth of lung, colon and leukemia cancer cells without affecting growth of healthy cells. Decreased cancer development is also seen in animals given anthocyanins. Black raspberries (containing ellagic acid which similar to resveratrol) prevented chemically induced esophageal cancer in one rat study. Strawberries, cranberries, and walnuts also contain ellagic acid. Ellagic acid also blocks metabolic pathways that can lead to cancer. In animals, it has inhibited development of colon, esophageal, liver, lung and skin cancers stemming from a variety of carcinogens. An essential question remains: Do normal portions of berries give us enough phytochemicals to get protective benefits or do we need to eat larger portions than standard 1/2 cup servings? Some research does suggest that concentrations normally found in the blood after eating berries are enough to substantially decrease cancer cells’ growth and to stimulate their self-destruction, but more study is needed.
Resveratrol and
Pycnogenol are found in red grapes. Resveratrol is a
potential anti cancer agent (Jang, M, Science, Vol 275, 1997). Resveratrol is
most concentrated in red wines from cold regions (
Apples: An apple a day may keep colon cancer away, according to a team from the French National Institute for Health and Medical Research. The BBC News Online reports that the magic ingredient is thought to be chemicals called procyanidins that have been shown to significantly reduce the number of precancerous lesions in lab animals. The research could lead to new cancer treatments. "For now, our work suggests that eating the whole apple, including the skin, might offer some anti-cancer benefits," lead study author Francis Raul told the BBC.
· Crucifers- are vegetables that contain special cancer fighting nutrients (indoles and sulforaphanes) that offer some cancer protective effects, especially breast cancer (Zeligs, J of Medicinal Foods, 1998 and Michnovica, J Natl Cancer Inst, 1997). Crucifer foods include broccoli, cabbage, cauliflower, Brussels sprouts, mustard greens, collards, turnips, watercress and bok choy. Eat them raw or lightly steamed but avoid over cooking as heat destroys these special cancer-fighting nutrients. Broccoli Sprouts have 20-50 times more of these cancer fighting phytochemicals than the adult broccoli spears- use them liberally! Try for one serving of these crucifers per day for optimal cancer prevention.
·
Allium
Vegetables- include garlic, onions, leeks, chives and shallots. They
are loaded with selenium and sulfur rich amino acids and may be cancer
protective in general and reduced breast cancer in rodents (Advances in
Experimental Medicine and Biology, Vol 4.1, 1996).
·
Capsicum
Vegetables- include green/red
peppers and
· Fish Oil & Omega 3 Fatty Foods- Although high amounts of saturated fats and hydrogenated (trans) fats are associated with cancer; certain good, healthy fats (omega-3 fats) appear to be cancer protective (Nutrition Research, Vol 9, 1989; NCI Study, 1990; Bougnoiux P, BJ Cancer, 1994). Foods that contain these good omega 3 fats include cold-water fish, beans, raw nuts and flaxseeds/oil. Fish oil studies reveal anti-tumor effects by suppressing tumor growth and by tumor killing activity. Fish oil has been found to suppress both breast and colon cancer tumor cell growth and spread (Rose DP, J. Natl Cancer Inst, 1995 and Kontogiannea M, J Surg Res, 2000).
·
Lignans- slow down cancer spread and act as anti
estrogens. Lignan containing foods include flaxseed, whole grains (oats and
rice), legumes (lentils, peas, beans), walnuts and
seeds.
· Soy Foods- the effects of soy phytoestrogens on cancer are still being investigated and controversial. The National Cancer Institute is promoting soy’s role in protecting against breast and prostate cancer (JAMA, Vol 275, 1996). There are some conflicting results and can be explained by the fact that isoflavones are selective as to where in the body they are a “pro-estrogen” and where they act as an “anti-estrogen.” They may also be pro or anti estrogen depending on the dose-At low doses isoflavones have an estrogen-like stimulating effect, while at higher doses it appears to have anti estrogen effects. In the absence of any estrogens, genistein in low doses has a weak pro estrogen effect on breast cancer cells in a test tube (Hsieh, Cancer Res, 1998).
However, in that same test tube, when adding higher doses of genistein, it inhibits the growth of breast cancer cells (Zava, Nutr Cancer, 1997 and Peterson, Cell Growth Diff, 1996). That being said, in over 150 test tube studies, genistein has been found to inhibit the growth of cancer cells (Messina, Adjuvant Nutrition in Cancer Treatment Symposium, 1995 and Fotsis, Baillieres Clin Endocrinol Metab, 1998). Soy phytoestrogens inhibit the proliferative effect of both estrogens and xenoestrogens (chemicals that act like estrogens in the promotion of breast cancer) (Herman, J Nutr, 1995 and Verma, Nutr Cancer, 1998). An Italian test tube study found that the combination of genistein and the chemo drug Adriamycin showed an increased, synergistic effectiveness in halting human breast cancer cell growth (Monti, E, Anticancer Res, 1994).
Of the 25+ animal studies performed with soy, roughly 65% of them revealed a cancer preventing effect of soy (Messina, Nutr Cancer, 1994).
Epidemiological studies that have looked at the amount of soy in the diet and the incidence of breast cancer have reported that soy may be protective against cancer (Persky, J Nutr, 1995).
One case controlled study of 144 pairs of Australian women with newly diagnosed early breast cancer found three was a substantial reduction in breast cancer risk among women with high intake of phytoestrogens (Ingram, Lancet, 1997). In somewhat contradiction to these studies, other human studies have shown the soy isoflavones can stimulate the growth of normal breast tissue (McMichael-Phillips, Am J Clin Nutr, 1998 and Petrakis, Cancer Epidemiol Biomarkers Prev, 1996). Another human study revealed soy consumption decreased total estrogen and the estrogen metabolites that may be cancer stimulating (Xu, Cancer Epidemiol Biomarkers Prev, 1998).
Although encouraging, the human studies on soy and cancer are small, preliminary and are by no means conclusive. There are no well-controlled randomized human trials evaluating soy and female cancers. Soy rich foods also improved prostate health by blocking production of the testosterone (J Endocrinology, Vol 147, 1995).
The following
precautions concern high dose soy intake:
· High doses (200 mg/d) of soy isoflavones may inhibit thyroid function.
· High doses (100-200 mg/d) of soy isoflavones can decrease estrogen levels in the premenopausal women. This may be good in women with an estrogen dominant state but may be undesirable in a women with a low estrogen state (Kronenberg, Menopause, 1999)
· High soy diet was shown to interfere with coumadin (warfarin) therapy in patients with high cholesterol and after by pass surgery (Gaddi, Curr Ther Res Clin Exp, 1989).
· Soy beans can be difficult for some to digest and cause gas and stomach upset
· Soy contains high amounts of phytates that can block to absorption of calcium, magnesium, iron and zinc. Fermented soy products such as tempeh and miso have reduced amounts of phytates due to the fermentation process. Eating soy with meat or fish reduces the mineral blocking effect of phytates.
· Some express concerns about high dose processed soy products and recommend just using the fermented types (tempeh and miso) and soy sprouts until more is known about the effects of high dose soy (Fallon and Enig, Health Freedom News, 1995).

Nutritional
Supplementation
“The proper mix of nutritional therapy and conventional treatments gives cancer patients a fighting chance.”
Patrick Quillin, Ph.D., R.D.
Dosage recommendations are geared toward our recommended prevention doses. In no way does this discussion imply that any of these are treatment recommendations for your individual condition. Treatment doses of these antioxidants should be individualized to each person’s unique biochemistry and medical condition under the supervision of a health care provider knowledgeable in this area of targeted pharmacological nutritional therapy.
Antioxidants
There is currently much controversy over the role of antioxidants when
used together with standard cancer therapy like chemotherapy and radiation.
Many medical and radiation oncologists recommend that their patients not take
antioxidants while undergoing chemotherapy or radiation. Lets
look at the facts concerning antioxidants before we rush to harsh conclusions.
Antioxidants in general reduce the risk of cancer, improve over 100 health
conditions, improve health and well-being, prevent and/or lessen the side
effects of chemotherapy and help in cancer healing and recovery (Moss, R,
Comprehensive Cancer Care 2000, Virginia). In a review of 130 studies on
antioxidant (Vitamins C, E and Beta carotene), 120 of them documented their
protective effects in cancer prevention (Block G, Nutr Reviews, 1992). Roughly
100 test tube studies and 100 animal studies have demonstrated that
antioxidants protect the healthy tissues and cells of the body while allowing
the cancer tumor cells to become more vulnerable to the effects of chemotherapy
and radiation (Shimpo K. Am J Clin
Nutr, 1991 & Okunieff P, Am J Clin
Nutr, 1991 and Simone, Comprehensive Cancer Care 2000, Virginia). There are
only a few human studies that have looked at antioxidants in cancer treatment
and there are no human studies that have found antioxidants to decrease or
interfere with the effectiveness of chemotherapy or radiation therapy!
·
Oncologist
at West Virginia Medical School found that a once a day vitamin plus the
following antioxidants of Vitamin A (40,000 IU), Vitamin B6 (100 mg), Vitamin C
(2000 mg), Vitamin E (400 IU) and Zinc (90 mg) decreased bladder cancer
recurrence by ½ (Lamm, DL, J Urol,
1994)
·
A study
involving 18 patients with lung cancer, including 5 in the advanced stage, were
treated with standard chemotherapy and radiation. They were also given
megavitamin and antioxidant therapy that included 3-800 IU of Vit E and
2000-5000 mg of Vitamin C. 8 of the 18 had a 6 year survival (44%) compared to
the normal 1% expected survival at 30 months with conventional therapy alone (Jaakkola K. Anticancer Res,
1992).
·
A non
randomized trial of 129 cancer patients (included breast, ovary, uterus, cervix
and other cancers) receiving conventional cancer treatments were studied. A
control group of 31 patients who did not receive additional nutritional support
lived an average of less than 6 months. The other 98 patients received large
doses of vitamins and antioxidants (Vit C @ 12+ grams/d, B3 @ 1.5-3 g/, B6 @
250 mg/d, Folic Acid 5-10 mg/d, Vit E 800 IU, Beta-carotene2 25-50,000 IU,
Selenium 200-500 ug, Zinc 220 mg, CoEnzyme
Q10 @ 300mg/d). Of these 98, 19 patients lived 10 months (75% improvement over
the group who did not get nutritional therapy with their regular cancer
therapy), 47 patients lived an average of 6 years and 32 patients who lived
more than 10 years. (Hoffer A, J Orthomol
Med, 1990, 1993, 1996).
The following discussion reviews the most common antioxidants that are
used in supplementation form.
·
Vitamin
A- Enhances cancer cell death
in test tube experiments and lessens the harmful effect of the chem. Drug
Adriamycin on the heart. It has been tested in Japanese clinical cancer trials.
Recommended doses in the non-pregnant women would be 5000-10,000 units per day.
Vitamin A is fat-soluble and can accumulate in the body. High doses can be
toxic, especially in liver and kidney disorders.
·
Vitamin
C- In September, 1999 an
article published in the journal Cancer
Research fueled the antioxidant
controversy by concluding that Vitamin C interferes with chemotherapy. However,
what the Memorial Sloan Kettering study actually found was that, in a test
tube, more vitamin C went into cancer cells than normal cells. The researchers
then falsely concluded that Vitamin C was bad for cancer. Vitamin C acts as
both an antioxidant and pro-oxidant and once inside a cancer cell it can
increase the effectiveness of chemotherapy, NOT decrease it! In a review of 90
epidemiological studies revealed the vast majority found statistically
significant preventive effects of vitamin C in cancer. (Block, G. Am J Clin Nutr, 1991). Vitamin C also protects normal cells from
the toxic effects of Adriamycin (Fujita K. Cancer Res, 1982), prolongs the lives of test animals, and
enhances the drug cisplatin effects. In a test tube,
Vitamin C enhances the effectiveness of chemo drugs against brain cancer cells
(Prasad KN. Proc. Natl Acad. Sci,
1979). In a human study, 50 cancer patients were divided into two groups- both
received radiation therapy but only one group also received 5 grams of Vit C
per day. After one month, 87% of the vitamin C group had a complete response to
therapy but only 55% of the radiation only group achieved similar results (Hanck, AB. Prog Clin Biol Res, 1988). In a test tube,
Vitamin C has been shown to inhibit cancer cell growth (Bram S, Nature, 1980;
Park
·
Vitamin
E- Another recent animal study
on Vitamin E added to the antioxidant controversy. Researchers at the
·
Beta
Carotene and Other Carotenoids-
Beta carotene reduces the harmful effect of Adriamycin
on the heart and also reduces the general toxicity of the chemo drugs cisplatin and L-PAM. However, we do not recommend taking a
beta-carotene supplement by itself without taking other balanced carotenoids in
combination with it. Isolated beta-carotene supplementation has been shown to
be potentially harmful in smokers and alcohol drinkers (NEJM, 1994, Omenn GS, Cancer Res, 1994; Rowe,
Lancet, 1996). An example of a balance carotenoids supplement would be: beta
carotene, 5000 IU; alpha carotene 1-3 mg; gamma carotene 1 mg; lycopene 5+ mg;
lutein 6+ mg; zeaxanthin 0.5+ mg; cryptoxanthin 1+
mg. Don’t forget the food sources of these carotenoids as nature has already
made them in the best possible combinations. The cancer drug methotrexate
decreases the absorption of carotenoids. Furthermore, high carotenoids may
decrease Vitamin E levels and it should be supplemented if you are taking a
carotenoids supplement.
·
Selenium- Has been shown to reduce the toxic effects
of adriamycin, cisplatin without interfering with their cancer killing
ability. It is toxic to leukemia cells in a test tube. Typical doses range from
100-400 micrograms/day with an average dose of 200 micrograms/day.
·
Pycnogenol- is an antioxidant found in pine bark and
red grape skins (red wine and purple grape juice) and is 20 times more powerful
than vitamin C and 50 times more powerful than vitamin E. One report noted that
pycnogenol slowed the mutation of cancer cells (Brown, S & White, D.
International Symposium on Pycnogenol, France, 1990). We are unaware of any
human trial of pycnogenol in cancer treatment. Typical doses range from 25 to
100 mg per day.
·
Resveratrol- is discussed in the food section above.
Supplemental dose is 1000 mg once or twice per day.
·
Lipoic
Acid- is an antioxidant found
in small amounts in spinach, broccoli, beef, yeast, kidney, and heart. Our
bodies also make lipoic acid. It is unique in that this antioxidant is active
in both the water and fat compartments of our bodies. Other antioxidants are
active in one place alone, i.e. Vitamin C in the water based tissues and
Vitamin E in the fat based tissues. Furthermore, it recycles and potentates
other antioxidants such as Vitamin C and E. Currently there are no established
recommended doses. Typical doses for health maintenance and disease prevention
are 30-100 mg per day. Higher doses have been used in diabetic nerve problems
(300-900 mg per day). It should be dosed 2-3 times per day because it has a
short life in the body (just like Vitamin C). We are unaware of any human
cancer trial using this supplement for therapy.
· Coenyzme Q10 (Ubiquinone)- is an antioxidant that increases energy production in the cells, especially heart cells. Its most useful applications are in heart conditions. It may reduce the heart toxicity from the chemo drug Adriamycin (Folkers K, 1981 and Okuma, 1984). One small study suggests possible benefits in breast cancer. Of 32 women given CoQ10 in doses of 90-400 mg per day along with other antioxidants and essential fatty acids, 6 had partial remission and 1 had complete remission. At the end of 2 years, all 32 women were still living (four deaths would have been expected given the natural course of breast cancer), (Lockwood K, Biochem Biophys Res Commun, 1994). Typical doses range from 30-100 mg per day. We recommend a product in a gel cap with oil inside as this type of preparation increases absorption by 50% (50 mg in an oil gel cap = 75 mg in a dry powder capsule).
Phyto-nutrients (Herbal
Therapies)
Green Tea- Green tea appears to inhibit the spread of prostate cancer in several ways. Research from scientists at the University of Wisconsin and Case Western Reserve University in Cleveland backs up previous research that showed green tea polyphenols, also called GTP, stopped the development of prostate cancer and its growth by explaining how they do this. The researchers found in a study of mice that the green tea polyphenols targeted the molecular pathways that controlled the proliferation and spread of prostate tumor cells to stop them dead in their tracks. The polyphenols did something else, too. They also starved the cancerous prostate tumors by inhibiting the growth of the blood vessels that feed them. Green tea may be the No. 1 drink for your good health. In addition to its cancer-fighting benefits, it's also been shown to reduce heart disease risk. The study findings were published in the Journal Cancer Research.
Medicinal Mushroom Extracts- There are several mushrooms that have been used medicinally for their immune enhancing activity. The food value and healing qualities of mushrooms have been known for thousands of years. Fungi were the first sources of antibiotics such as penicillin, erythromycin and tetracycline. The medicinal mushrooms include Shiitake, Maitake, Reishi, Cordyceps and Coriolus. These mushrooms contain immune enhancing "glycan" molecules specifically named alpha-glucan (AHCC), beta-glucan, proteoglycans (PSK), and arabinogalactans. Mushroom extracts have been shown to increase NK cell activity of the immune system. NK cells are the chief immune cells which attack and destroy tumor cells in the body. One study found an 80% tumor regress in animals when treated with extracts of maitake, shiitake and reishi extracts (National Cancer Center, Japan, 1995). Shiitake (AHCC) has been shown to prolonged survival in a group of 126 patients with liver cancer (Abstract, Japan, 1992) and increased tumor regression in patients with lung, breast, stomach, esophagus and colon cancer (Abstract, Japan, 1996). Maitake (beta glucan) was studied in 165 patients with advanced cancers revealing clinical benefits of >50% in breast, lung, liver cancers and <50% benefits in leukemia, prostate, brain, stomach and bone cancers. This study also revealed "superior" inhibition of tumor growth with maitake (80%) compared to chemotherapy (45%) (Nanba, Japan, 1995). Coriolus (PSK extract) was found to prolong survival in post-operative gastric cancer, colon cancer and lung cancer (small cell) (Wong, J of Intern Med Res, 1994). Other cancers that have been shown to be benefited by PSK include head/neck cancer, esophageal cancer, and breast cancer. In summary, mushroom immunoglycans are clinically proven to help extend survival and improve quality of life in cancer. They are non-toxic and safe for long-term use. They are well suited for comprehensive cancer management, especially when used in conjunction with conventional therapies such as chemotherapy and radiation, for indeed, all of the best clinical results with PSK were in conjunction with standard therapy.

Daily Survival Kit for Serious Illness
Adapted from Thomas L. McDermitt, “A long-time cancer patient and skeptic”
You don’t have to agree with all of this all of the
time. But if it generally speaks to you, try to read all or parts of it every
day, or have it read to you. Part of the help is in the doing, regardless of
your attitude or emotions on that day. On some levels the help is gradual and
often not externally evident.
1. Today I am going to try to live through this day
only, and not dwell on or attempt to solve all my problems at once; just focus
on the piece that is today. I can do something for several hours that would be
difficult to even think about continuing for several months.
2. Just for today, I am willing to accept the
possibility that there is a purpose to this suffering; that it can be a source
of meaning and growth for myself and others, though I may not always recognize
the ways. And it seems possible that this suffering will not be in vain,
because of what may be some kind of existence beyond.
3. Just for today, let me remind myself that I am a worthwhile
person; worth loving despite my weaknesses and limits. I deserve the efforts of
others to help me through my illness.
4. Just for today, I want to be aware that it is all
right to want things from others at times. Illness brings out and intensifies
the small child in all of us. And if I feel hurt when those who care for me
cannot be there, it may help to remember that they also have needs, frailties
and limitations of their own. A lack of response does not mean that they are
personally rejecting me.
5. Today I may feel the need to complain a great deal;
I may have little tolerance; I may cry; I may scream. That does not mean that I
am less courageous or less strong. All are ways of expressing anger over this
mess, of mourning my losses. Endurance itself is courage.
6. It is my life at stake now. So maybe today I can
allow myself to be a little less concerned about the reactions or impressions
of others. Maybe I can allow myself to feel a little less guilty or bad about
what I did not accomplish or give. Perhaps today I can be a little more gentle toward myself.
7. Surviving this may seem so difficult. At times it
may seem impossible- that I have had enough. Down the line I will know if and
when I have had enough, when I cannot push the limits any further. I will have
the right to choose to take a break and rest, without feeling that I am “giving
up.” But today I think I can deal with this illness. Sorrow runs very deep, but
I know I can rise again.
8. Just for today, maybe I can give healing “the
benefit of the doubt.” The treatments I am using are powerful; the natural
healing capacity of my body is powerful. Perhaps there is even healing power in
my will to struggle, and in the collective love and will of others.
9. Just for today, perhaps I can take heart that we
are all connected. And I may still have some things left to contribute to the
family of man; some light to add to the light. Even now my endurance (however
imperfect) is a gift, an inspiration for others in their struggles.
10. It seems reasonable that there is a season for
everything, and a time for every purpose. Pain, weakness, and exhaustion may
distort my senses and spirit. Today, however, I can at least find some hope in
nature’s way, if not in some master plan. The chances are fairly good, and it
seems worthwhile to hope that I will have some cycle of wellness yet.
