Chemotherapy involves administering drugs that kill cancer cells or stop them from growing. Chemotherapy is usually an outpatient procedure.
The way chemotherapy is administered depends on the type of cancer, its stage, and where it is located. Your doctor may use systemic therapy, which is administered to the whole body via a pill, an injection, or dissolving wafers placed inside the body.
For some types of cancer, you may receive regional chemotherapy, which is administered to only a certain part of the body by placing it into the spinal column, in the abdomen, or in an organ such as the liver.
Chemotherapy may be used alone or in combination with other treatments. Chemotherapy may be used either before surgery to shrink larger tumors or after surgery to prevent the tumor from coming back.
