AT THE SAN ANTONIO Breast Cancer Symposium, several breast cancer experts interviewed by The ASCO Post noted that the approved dose of tamoxifen was arbitrarily set, and the optimal dose is actually unknown. Studies of lower-dose tamoxifen, therefore, are welcomed. Virginia G. Kaklamani, MD,...
A VERY LOW DOSE of tamoxifen—5 mg/d, given for 3 years rather than 5 years—halved the risk of breast cancer recurrence or new lesions over placebo in women with breast intraepithelial neoplasia, without producing the usual toxicities seen with the standard dose, Italian researchers reported at the...

Women aged 75 years and older may benefit from continued screening mammograms because of the comparatively high incidence of breast cancer found in this age group, according to a study presented at the Annual Meeting of the Radiological Society of North America (RSNA) (Abstract SSA01-04)....
A new, large-scale study of more than 5 million mammograms found that annual mammography screening beginning at age 30 may benefit women with at least 1 of 3 specific risk factors: dense breasts, a personal history of breast cancer, or a family history of breast cancer. The study was presented at...
