The study, funded by a pomegranate juice manufacturer, tested men's levels of prostate-specific antigens (PSAs), a chemical produced by prostate cancer cells, and measured how long it took the PSAs to double in each patient. The men who drank a glass of pomegranate juice daily showed a doubling time of 54 months on average, as opposed to the standard average of 15 months, meaning that pomegranate juice slowed the growth of prostate cancer tumors to less than one-third the typical rate.
The participants showed suppressed PSA levels despite the fact that they were only drinking pomegranate juice, and not supplementing the drink with costly prescription drugs or prohibitively expensive conventional cancer treatments.

Let's take a look at it: The job of a doctor (a General Practitioner, or GP) is primarily to diagnose disease, treat symptoms and make referrals to other specialists for surgery, lab tests or other procedures. (Good doctors also help educate patients, but that's the exception, not the norm.) Patients don't go see a doctor unless there's something wrong with them. When they do see the doctor, the doctor's job is to patch them up, make the pain go away, make the swelling go down, stitch up the cut, prescribe drugs or whatever is immediately necessary.

COLUMBUS , Ohio – Researchers here have learned how a derivative of vitamin E causes the death of cancer cells. The researchers then used that knowledge to make the agent an even more potent cancer killer.

The compound, called vitamin E succinate, or alpha tocopheryl succinate, is taken by some people as a nutritional supplement, mainly for its antioxidant properties. In addition, it has a weak ability to kill cancer cells, and it has been tested as a cancer chemopreventive agent.
The substance kills cancer cells by causing them to undergo a natural process known as programmed cell death, or apoptosis. Until now, no one knew how the agent caused this to happen.
These findings answer that question and also indicate that the molecule's antitumor activity is separate from its antioxidant effect.
The study, led by researchers with The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James), is published in the April 28 issue of the Journal of Biological Chemistry.
“Our findings could lead to a potent chemopreventive agent that has both strong anticancer and antioxidant properties,” says principal investigator Ching-Shih Chen, professor of pharmacy and of internal medicine and a researcher with the OSUCCC-James.

NEW YORK (Reuters Health) - High-dose intravenously administered vitamin C apparently led to longer-than-expected survival in three patients with advanced cancer, doctors at the National Institutes of Health in Bethesda, Maryland and colleagues in Canada report. Two of the three patients are still alive without evidence of disease.
In the three cases described in the Canadian Medical Association Journal, vitamin C was given intravenously at doses ranging from 15 to 65 grams to produce plasma concentrations that cannot be achieved by taking vitamin C by mouth.

It has been estimated that 30–40 percent of all cancers can be prevented by lifestyle and dietary measures alone. Obesity, nutrient sparse foods such as concentrated sugars and refined flour products that contribute to impaired glucose metabolism (which leads to diabetes), low fiber intake, consumption of red meat, and imbalance of omega 3 and omega 6 fats all contribute to excess cancer risk. Intake of flax seed, especially its lignan fraction, and abundant portions of fruits and vegetables will lower cancer risk.
Allium and cruciferous vegetables are especially beneficial, with broccoli sprouts being the densest source of sulforophane. Protective elements in a cancer prevention diet include selenium, folic acid, vitamin B-12, vitamin D, chlorophyll, and antioxidants such as the carotenoids (α-carotene, β-carotene, lycopene, lutein, cryptoxanthin). Ascorbic acid has limited benefits orally, but could be very beneficial intravenously.
Supplementary use of oral digestive enzymes and probiotics also has merit as anticancer dietary measures. When a diet is compiled according to the guidelines here it is likely that there would be at least a 60–70 percent decrease in breast, colorectal, and prostate cancers, and even a 40–50 percent decrease in lung cancer, along with similar reductions in cancers at other sites. Such a diet would be conducive to preventing cancer and would favor recovery from cancer as well.
