DISEASE: CANCER

2014 - A recent research review justifying the use of intravenous vitamin C to treat cancer. And a review on why vitamin C kills cancer cells without harming normal cells. And further links from a reader about cancer and vitamin C: Vit C therapy: more links to iv vitamin C research: To take chemo or not

2012 - I am currently doing research and submitting proposals on the use of vitamin C to treat and prevent cancer. This has lead to reading about many strategies to treat or prevent the recurrence of cancer. Please see Cancer Prevention for what I have found. Also see cancer references for a few of exciting articles and utube reports. Also enjoy what follows written previously.

Overview of cancer: When you are not pregnant, it is probably best to get 800 mcg of folate per day. In 2008, it was reported that for others, especially older people, levels of folate beyond 400 mcg per day may increase the risk of cancer. This explanation of how cancer happens may help.

In stage 1, normal cells get a mutation that leads to "initiation", which is a term indicating the cell has become immortal for the purpose of dividing endlessly. Folate greatly reduces the risk that your cells will be initiated, so it is important to get enough folate.

In stage 2, initiated cells undergo "promotion". Promotion occurs when the initiated cell divides many times. When this happens, the growth control mechanism of the cell is likely to break, so the initiated cell divides rapidly, thus becoming a tumor. This process is facilitated by folate, increasing the risk of cancer.

In stage 3, the tumor cells, which are already initiated and promoted, metastisize. That means they lose their normal attachment properties, and migrate around the body, causing tumors in many places. Metastasis is also facilitated by high levels of folate.

Thus, getting more than 400 mcg of folate is especially important when young, so cells do not become initiated. But as we get older, most people have many initiated cells already, and too much folate will encourage them to become cancer. But you must continue to get the 400 mcg per day, because otherwise more cells will get initiated.

DIET AND CANCER
Notes on foods related to cancer- apples, broccoli, walnuts reduce risk and growth of cancers (from 2009 AGE meeting) , Fish and omega-3s (from Juvenon Newsletter- The subjects with aggressive prostate cancer reported consuming, on average, significantly less fish per week, as compared to the cancer-free controls.)  Fluoridated water increases risk of bone cancer 5.5x (http://www.webmd.com/cancer/news/20060406/does-fluoridation-up-bone-cancer-risk) (link: cancer; added 6/2009)

DETAILS: For exciting news in summer 2006 about intravenous vitamin C for cancer treatment, see the Linus Pauling Institute Newsletter

NOTES ON NUTRITION DURING CHEMOTHERAPY

OVARIAN CANCER

PROSTATE CANCER


1) FOODS TO REDUCE CANCER RISK Cruciferous vegetables: These dramatically reduce the risk of a variety of forms of cancer. Cruciferous is a word that is used to describe a certain type of vegetable. Another term that describes these same vegetables is brassica. Vegetables that are considered to be part of the cruciferous (brassica) vegetable 'family' include asparagus, beets, bok choy, broccoli, Brussels sprouts, cabbage, cauliflower, chard, collard greens, kale, kohlrabi, rutabagas, turnips, and watercress.

2) There was an entire symposium on Nutrition and Cancer published by AJCN in 2003. We are learning incredible amounts about diet and cancer, and now tailored to specific types of cancer. For preventing cancer, there is more generic guidance. But if you have a specific family history or risk for particular types of cancer, it is important to do research on your particular concern through both good health practionner and good search of the scientific and medical literature.

"Three years ago research at Baylor College of Medicine in Houston showed that people who already had ...skin cancer and were put on a low-fat diet (20% or less of their calories came from fat) developed only one-third as many lesions and tumors as those on a high-fat diet (38% of calories from fat). Now, as reported in the JAMA, new research finds that a low fat diet (less than 20% of calories from fat, with at least five servings of fruits and vegetables daily) significantly reduces the development of actinic keratoses as well as actual cancers."

Risk rose with nitrities and protein, and decreased in proportion to intake of ascorbic acid, beta-carotene, alpha-tocopherol, and vegetable fat. The associations with nitrite and beta-carotene tended to fade, however, in multivatriate analyses adjusting for intake of other nutrients."

The potential role of calcium in the prevention of colon cancer is being pursued...an inhibition of cancer by dietary selenium...but enhanced carcinogenesis was observed in some studies on skin, liver, and pancreas cancer.
