This system carries lymph fluid through the body, and it can carry cancer cells as well. This is why doctors often remove lymph nodes near the tumor during surgery to see if they contain cancer cells. In some cases, surgery is also used to reconstruct areas of the body damaged by cancer or its treatment. For more information about cancer surgery, please consult your health care provider. It is used primarily to treat cancers that can't be removed surgically, or to destroy cancer cells that remain after surgery.
Chemotherapy is given either by mouth or by injection into a vein or muscle.
The length and frequency of therapy depends on the type of cancer, the type of drugs used, and the body's response to them. Unfortunately, the anti-cancer drugs not only attack cancer cells, but may also damage normal cells. That is why chemotherapy often causes side effects such as nausea, vomiting, hair loss, fatigue, diarrhea, and low red and white blood cell counts. The side effects tend to vary with the amount and type of chemotherapy used. Although side effects are unpleasant, they will subside once treatment stops.
