Letwell Tablet belongs to the group of anti-cancer medicines called aromatase inhibitors used to treat breast cancer in women who have gone through menopause (cessation of menses periods). Breast cancer is a type of cancer that develops in breast cells stimulated by the female sex hormone known as estrogen.
 
Letwell Tablet contains 'Letrozole' that works by blocking the aromatase enzyme, which is involved in the production of the estrogen hormone. The cancer cells require estrogen for their growth. Hence, by blocking the aromatase enzyme, Letwell Tablet prevents the growth of cancer cells. Thereby Letwell Tablet helps in preventing or stopping the growth of spreading the tumours (cancer cells) to other body parts.

You are advised to take Letwell Tablet for as long as your doctor has prescribed it for you depending on your medical condition.
