Chemotherapy is a type of cancer treatment that uses drugs to destroy cancer cells. It can be used to treat many types of cancer, including gynocological cancers such as ovarian, cervical, uterine, and vulvar cancer. Chemotherapy works by attacking rapidly dividing cells, which includes cancer cells. It also affects healthy cells that divide quickly, such as those in the stomach, intestines, and bone marrow. This can lead to side effects such as nausea, vomiting, hair loss, mouth sores, and fatigue. Chemotherapy is usually administered in cycles. For most gynocological cancers, chemotherapy is used in combination with other treatments, such as surgery or radiation therapy. The goal of chemotherapy is to reduce the size of the tumor or to prevent the cancer from spreading. The type of chemotherapy used will depend on the type of cancer and its stage. There are several different types of chemotherapy drugs, including alkylating agents, antimetabolites, topoisomerase inhibitors, and plant alkaloids. Each type of drug has its own advantages and disadvantages. The side effects of chemotherapy can be managed with medications and other treatments. It is important for patients to discuss all of their treatment options with their doctor.
