Don't know: Generally speaking these types of drugs are given for 5 years. However they have some side effects which may shorten the time they can be taken.

About 5 yrs: Usually 5 yrs is recommended. There are ongoing trials for longer durations of treatment. Some women who are premenopausal when they start are put on tamoxifen then switched over after menopause, this could also be for 5 yrs total or 5 yrs in addition to the tamoxifen. Depends on the prescribing doctor.

Tamoxifen is: Beneficial for 5 years, longer use provides no protection. Anastrazole and Letrozole are newer, are being tested beyond 5 yrs. These are indicated in tumors with + estrogen receptor. The use of these drugs for prevention without er+ breasst cancer is not proven. Protracted beyond 5 yrs of teh aromatase inhibitors is not yet proven.
