Chemotherapy involves delivering a drug to kill cancer cells. These drugs interfere with cell division and do not allow cancer cells to divide. Chemotherapy may be used alone or with surgery or radiation therapy to improve overall clinical outcomes. Chemotherapy shrinks the tumor when used before the surgery and kills the remaining cancer cells when used after the surgery.
Chemotherapy drugs are available in tablets, capsules, creams, infusions, and shots.
The side effects of chemotherapy are diarrhea, nausea, vomiting, hair loss, indigestion, mouth sores, loss of appetite, pain, bleeding, easy bruising, and loss of appetite.
