The 6-year survival rate for HRT users was 92% compared with 80% for nonusers (P = . 05) (Figure 2). Figure 3 shows survival curves for patients with tumors detected by palpation. The 6-year survival rate was 79% for HRT users compared with 76% for nonusers (P = .
Does hormone replacement therapy make your breasts bigger?
