What is the success rate of hormone therapy?
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 = .
At what age should a woman stop taking estrogen?
