Dotsie, to reiterate: I took Tamoxifen for 5 years (the recommended duration) because it lowered a 40% chance of recurrence to 20%. Now I take Femara (Letrozole) because clinical tests show that women who took Tamoxifen for 5 years, then Femara for 3, have a (50%?) lower recurrence and death rate than women who didn't do the Femara. Because of my initial high chance of recurrence, I feel it's worth the risks.
