What is Anastar tablet?
Anastar tablet is a medicine used to treat breast cancer in women who have gone through menopause. It works by lowering the body's estrogen levels. Estrogen is a hormone that can fuel the growth of some breast cancers. By reducing estrogen, Anastar tablet slows or stops the growth of these cancers. It's used in several ways: after surgery to help prevent cancer from returning (adjuvant treatment); as the first treatment for advanced or spread breast cancer (first-line treatment); or when another drug, tamoxifen, stops working (second-line treatment). It may also be used to prevent breast cancer in women at high risk. * **Menopause:** The time in a woman's life when her periods stop permanently. * **Estrogen:** A female sex hormone. * **Adjuvant treatment:** Treatment given after the main treatment (like surgery) to reduce the risk of cancer returning. * **Metastatic breast cancer:** Breast cancer that has spread to other parts of the body. * **First-line treatment:** The first treatment used for a condition. * **Second-line treatment:** A treatment used when the first treatment doesn't work.

Anastar tablet is a medication, often used to treat certain types of breast cancer. It works by lowering the level of estrogen in the body, which can help slow or stop the growth of some breast cancers that need estrogen to grow.

Always follow your doctor's recommendations and discuss any concerns you have about your medication.
What disease or symptom is Anastar tablet used for?
Anastar tablet is a medication used to treat certain types of breast cancer in women who have gone through menopause. It's used in several ways: * **After surgery:** To help prevent breast cancer from returning after surgery for early-stage cancer where the cancer cells have hormone receptors (hormone receptor-positive). *Hormone receptors* are proteins on cancer cells that allow hormones like estrogen to fuel their growth. * **For advanced cancer:** As the first treatment for advanced or metastatic (spread to other parts of the body) breast cancer where the cancer cells have hormone receptors (or it is unknown if they have them). *Metastatic* means the cancer has spread beyond its original location. * **After another treatment fails:** To treat advanced breast cancer when another drug, tamoxifen, stops working. Anastar tablet is unlikely to help if the cancer doesn't have hormone receptors or if the cancer didn't respond to tamoxifen.
