Introduction

Tucanat 150mg Tablet is a medicine used to treat a specific type of breast cancer called HER2-positive breast cancer, especially when it has spread to other parts of the body, including the brain. It is usually given along with two other medicines—trastuzumab and capecitabine.

The active ingredient, Tucatinib, works by blocking a protein (HER2) that helps cancer cells grow. By doing this, Tucatinib helps slow down or stop the cancer from spreading further. Tucanat 150mg Tablet is a targeted therapy, not traditional chemotherapy, which means it attacks cancer cells more specifically and causes less harm to healthy cells. Treatment should always be taken under a doctor’s supervision with regular checkups to ensure safety and effectiveness.

• HER2-positive advanced or metastatic breast cancer
