New research presented at the annual conference of the American Association for Cancer Research suggests that vitamin D and cyclooxygenase-2 (COX-2) inhibitors may help reduce the risk of breast cancer. The findings may help women, particularly those at elevated risk, take steps to prevent the development of this disease, although experts caution that any anticancer benefits of the COX-2 inhibitors will have to be balanced against the drugs' cardiovascular risks.
Individuals who live in warm and sunny climates enjoy not only pleasant weather but also a decreased risk of developing some cancers. Epidemiological studies have demonstrated that there is higher mortality from colon, breast, and several other types of cancer in the northeastern United States than in the southwest and that the geographic distribution of these malignancies is related inversely to solar radiation (Grant WB. Cancer. 2002;94:1867-1875).
