Step-by-step explanation:
The most common ways to treat cancer include chemotherapy, radiation therapy, and surgery. These treatments are chosen based on factors such as the type and location of cancer, and whether cancer has spread. While surgery aims to physically remove the cancer, chemotherapy uses drugs to kill rapidly dividing cells, and radiation therapy employs ionizing radiation to target and destroy cancerous tissues. Additionally, treatments like immunotherapy are used to help the immune system fight cancer, and it is often used in conjunction with the primary treatments.
