BCPTBreast Cancer Prevention Trial. A study of 13388 women at increased risk of breast cancer (BC): in women age 60+, < age 60 but at increased risk of BC, or with history of lobular carcinoma in situ, and randomised to receive tamoxifen or placebo.
Tamoxifen reduces the risk of invasive BC by 49%; despite its side effects—e.g., increased risk of endometrial cancer, RR 2.53, stroke, pulmonary embolism and deep vein thrombosis—its use as a prophylaxis is appropriate in high-risk women.
