Hint:

Tamoxifen is crucial in preventing breast cancer recurrence by inhibiting estrogen-dependent tumor growth.

Answer 1

The Correct Option is C

Tamoxifen is a selective estrogen receptor modulator (SERM) that acts as an antiestrogen in breast tissue. It is widely used in the treatment of estrogen receptor-positive (ER+) breast cancer, blocking estrogen-mediated tumor growth. Tamoxifen exhibits agonistic effects in bone and uterus while antagonizing estrogen receptors in breast tissue.
