Reducing Cancer Risk

Doctors from the Mayo Clinic, Rochester, Minnesota, tested a new theory that vitamin K may protect against non-Hodgkin’s lymphoma (n-HL). Researchers measured the diets and supplement use of 603 people newly diagnosed with n-HL, and of 1,007 cancer-free people of similar age and lifestyle. In the first finding of its kind, those who consumed the most vitamin K-more than 108 mcg per day-were 45 percent less likely to develop n-HL compared to those who consumed less than 39 mcg per day.

Researchers in a vitamin study said that residents of Linxian, China, are undernourished and have high rates of esophageal and gastric cancers. For seven years, 29,584 Linxian villagers, aged 40  to 69, took a combination of 50 mcg of selenium, 400 IU of vitamin E, and 15 mg of beta-carotene per day, or several other vitamin combinations. Compared to all other groups two years later, those in the selenium-vitamin E-beta-carotene group were much less likely to have died from gastric or any other cancer, or from any cause. A full 10 years later, the selenium-vitamin E-beta-carotene group was still 11 percent less likely to have died from gastric cancer and 5 percent less likely to have died from any cause.

In a chemotherapy study, 644 cancer patients who had reported nausea after chemotherapy began taking ginger capsules or a placebo three days before their next treatment while continuing to take anti-nausea/anti-vomiting medicine. After the first day on ginger, while the placebo group still had intense nausea, those who took a 0.5 gram or 1 gram ginger capsule reported little or none.
