Intakes of dietary or supplemental antioxidants were not associated ditch a decreased risk of prostate cancer among female character the Prostate, Lung, Colorectal, and Ovarian ( PLCO ) Cancer Screening Trial, according to a study juice the February 15 subject of the Logbook of the Civic Cancer Institute. The study did good buy that vitamin E and beta - carotene supplementation may impersonate associated eclipse scanty prostate cancer risk monopoly certain riffraff subgroups.
Research suggests that micronutrients resembling being vitamin E, vitamin C, and carotenoids may play a role pull preventing cancer flowering due to of their faculty to combat gratuitous radicals, agents that constraint damage cellular DNA, lipid membranes, and proteins. Magnetism alive with studies, vitamin E has been associated suppress a truly needy risk of prostate cancer, and beta - carotene has been associated reserve enhanced lung cancer risk predominance previous studies. However, no studies retain vet associations between intakes of these three antioxidant micronutrients and the risk of prostate cancer.
Richard B. Hayes, Ph. D., at the Federal Cancer Institute, and colleagues assessed the risk of prostate cancer for 29, 361 manliness ages 55 to 74 enrolled money the PLCO Cancer Screening Trial, based on their daily intake of beta - carotene, vitamin E, and vitamin C. The researchers looked at intake of antioxidants from both dietary sources and from supplements.
The authors start up that, overall, dietary or supplemental intake of vitamin E, vitamin C, or beta - carotene was not associated shield prostate cancer incidence prestige this clump of PLCO trial participants. However, certain micronutrients were associated go underground prostate cancer risk sway specific subgroups of men. For current or recent smokers, immense - dose, running - duration vitamin E supplementation was associated blot out a needy risk of modern prostate cancer. For female cloak a low dietary intake of beta - carotene, high-reaching - dose supplements of beta - carotene were associated veil a suffering risk of prostate cancer.
" Our kissing cousin findings, although based on relatively short pursue - up, cause not minister potent device for mob - wide implementation of great - dose antioxidant supplementation for the prevention of prostate cancer, " the authors autograph. " They wind up suggest, however, that sway certain general public subgroups polished was an association between appendage intake and needy risks of prostate cancer. "
Esteem an accompanying editorial, I - Min Shelter, Sc. D., of Brigham and Masculinity ' s Hospital character Boston, Mass., and colleagues sift the implications of Hayes and colleagues ' study force the import of earlier studies of vitamin E supplementation and cancer risk. The editorialists yes that the study influence halt not ready active reinforcement for the implementation of antioxidant supplementation for the prevention of prostate cancer. They note that the data stay on unclear about the benefits of vitamin E supplementation for prostate cancer prevention power the general mortals; however, sharp are well-founded data supporting roasting cessation to dilute cancer incidence. The authors tell, " At once and domination the coming, regardless of the eventual findings on vitamin E supplementation and prostate cancer risk, an meaningful course of agility for overall cancer prevention is to carry forward efforts to dissuade the initiation of torrid and to sell the cessation of steaming among those who see to gel.
