Enhertu 100 mg Injection contains Trastuzumab, which is used for treating patients with HER2-positive breast cancer and HER2-positive metastatic gastroesophageal adenocarcinoma. This medicine works by inhibiting the excess production of a human epidermal growth factor receptor 2 (HER2) protein in the mammalian cells. This causes inhibition of the cancer cell growth and, finally, initiation of programmed cell death.

Breast Cancer: Breast cancer is a type of cancer with abnormal growth in the cells of the breast. There are different kinds of breast cancer, such as cancer occurring in lobules (glands that produce milk), ducts of the breast (the pathway that brings milk from glands to the nipple), and in the fatty tissue or the fibrous connective tissue within the breast. Symptoms of breast cancer include a lump in the breast, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, a lump or swelling under the arm, unexplained change in shape, size or appearance of the breast, peeling, flaking or scaling of the skin. 

Stomach Cancer (Gastric adenocarcinoma): It is a type of cancer that develops from the stomach lining. When the cancer cells spread to other organs of the body, it is called metastatic. This condition can occur mainly due to smoking, a highly processed or salty diet, and severe bacterial infection of H. pylori. Symptoms of stomach cancer include feeling bloated after eating, feeling full after eating small amounts of food, nausea, heartburn or indigestion.
