Too much of a good thing?

The next frontier of cancer research appears to be the study of nutrients and vitamins for cancer prevention, says a researcher at the University of Wisconsin. According to the Cardone Cancer Center, green tea and a nutrient in broccoli seem to hold the potential for preventing cancer. Additionally, Vitamin D, which can be found in dairy products and sunlight, is also being studied by Dr. Howard Bailey, profesor of medicine at the UW School of Medicine and Public Health.
Although few nutrients are proven to prevent cancer, a group of drugs have shown positive results. Tamoxifen, developed to treat breast cancer, and raloxifene, first used to prevent osteoporosis, can reduce breast cancer in high-risk women. Another FDA-approved cancer-prevention drug is the HPV vaccine for cervical cancer.
According to Bailey, research on drugs is making notable progress where the advantages of nutrients lags. The problem lies in determining the level of nutrients needed to create a measurable prevention of specific cancers. Bailey explained that this will be where researchers must focus their efforts in the future.
