Cancer is made up of cells that divide rapidly. This is how they grow into cancerous tumors and attack normal tissue.
Chemotherapy uses different chemicals to kill or prevent further growth of cancer cells.
Chemotherapy may be given by mouth or by injection through the skin into a vein. These treatments can be self-administered and last from as little as ten minutes to a few days. A portable pump for treatment into the veins is now available. This pump makes sure the prescribed dosage of medicine is given over the correct time period. A hospital stay is no longer necessary in most cases.
