Breast cancer, a malignancy that originates in the cells of the breast, is one of the most common cancers affecting women worldwide, though it can also occur in men. The complexity of breast cancer, with its various subtypes and stages, necessitates a tailored approach to treatment. Fortunately, advancements in medical science have led to the development of a diverse array of medicines designed to treat and manage breast cancer effectively. Treatment options for breast cancer include hormone therapies, which target hormone receptors on cancer cells to slow or halt tumor growth. Chemotherapy, another cornerstone of treatment, uses powerful drugs to destroy rapidly dividing cancer cells and is often employed to address tumors that have spread beyond the breast. Targeted therapies offer a more precise approach by focusing on specific molecular targets associated with breast cancer, such as HER2-positive tumors. Additionally, immunotherapy is emerging as a promising treatment, harnessing the body's immune system to fight cancer.
