Higher serum α-tocopherol and γ-tocopherol concentrations are associated with lower prostate cancer risk
Two forms of vitamin E - α- and γ-tocopherol - appear to lower the risk of prostate cancer by as much as 53 percent and 39 percent, respectively, based on the findings of a team of scientists from the National Cancer Institute, the Fred Hutchinson Cancer Research Center in Seattle and the National Public Health Institute of Finland. more

Intake of vitamin E (2-R isomers of α-tocopherol) and γ-tocopherol in a case-control study and bladder cancer risk
Consuming vitamin E (α-tocopherol) lowers the risk of bladder cancer, according to the findings of a case-control study led by Xifeng Wu, M.D., Ph.D., M.S., from the University of Texas M.D. Anderson Cancer Center in collaboration with researchers at Texas Woman's University, both in Houston.  more


Invisible light and special goggles may improve brain tumor surgery

Fox Chase Cancer Center research reveals how COX-2 causes ovarian cancer
Fox Chase Cancer Center scientists have identified how an enzyme called COX-2 may promote the development of ovarian tumors, adding further insight into the mechanism of COX-2 inhibitors and the prevention of this highly lethal disease. The data was presented today at the 95th Annual Meeting of the American Association for Cancer Research in Orlando, Fla.

"We have found that the over-expression of COX-2 correlates with the loss of the basement membrane in ovarian epithelium cells, thus promoting cancer," said Mike (Xiang-Xi) Xu, Ph.D., who heads the Fox Chase team in this research. "A COX-2 inhibitor may reduce the loss of basement membrane and thus decrease cancer risk." more

Catalase (CAT) genotype, dietary antioxidants, and breast cancer risk
In the first study ever to evaluate catalase (CAT) genotypes and breast cancer, researchers at Roswell Park Cancer Institute in Buffalo, N.Y., found that women with the most common genotype for reducing oxidative stress are at a reduced risk of developing breast cancer. Further, they can diminish their breast cancer risk even more by including ample fruits and vegetables in their diets.  more
