Reducing the Risk of Colon Cancer: Asprin, No; Hormone Replacement, Maybe
Randomized and observational analyses of data from a large prospective cohort study found no association between aspirin use and colorectal cancer after five years. (Article, p. 713.) An analysis of data from a second large prospective study found that the risk for colon and rectal cancers decreased by 35 percent among women currently using postmenopausal hormones, with a smaller reduction for past users. (Article, p. 705.) Long-term use did not provide more protection. An editorial praises research into prevention of cancer but cautions that the link between lower risk for colorectal cancer and hormone therapy may be caused by other factors, such as the overall health of the women who receive hormone therapy, and that little is known about the determinants of this cancer. (Editorial, p. 771.)

Breast Cancer Found at Same Stages in Older Black and White Women Who Have Regular Mammography
Differences in the severity of the tumor at diagnosis of breast cancer between black and white women are related to previous mammography use, a retrospective study of women aged 67 and older found. (Article, p. 729.) Black women were more likely not to have regular mammography and to be given a diagnosis of late-stage disease. An editorial says that clinicians must encourage underserved and minority women to have mammography. (Editorial, p. 773.)
