Used primarily in chemotherapy to treat various cancers, including Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, testicular cancer, breast cancer, and Kaposi’s sarcoma. It works by inhibiting microtubule formation during cell division, which prevents cancer cells from multiplying. Administered intravenously, it is often part of combination therapy regimens. Its effectiveness comes from targeting rapidly dividing cells, though it can also affect healthy cells, leading to side effects.
