Letrozole is an aromatase inhibitor used to treat hormone receptor-positive breast cancer in postmenopausal women. It works by blocking estrogen production, thereby slowing the growth of estrogen-dependent tumors. Letrozole is effective in managing breast cancer and preventing recurrence. In summary, Letrozole is vital for treating hormone-sensitive breast cancer.
Letrozole inhibits the aromatase enzyme, reducing estrogen synthesis and limiting the growth of estrogen-dependent tumors.
