Normally, cells divide and grow at a controlled rate. When there are “enough” cells, they stop dividing. Cancer cells divide and grow in an uncontrolled, purposeless way.
Chemotherapy is the use of chemicals to stop cancer cells from dividing and growing. Chemotherapy is a combination of the words “chemical” and “treatment.” It can also be called “anti-cancer” drugs.
In addition to stopping cancer cells from dividing and growing, immunotherapy increases the ability of the immune system to destroy cancer cells. Immunotherapy can interfere with a tumor’s ability to grow its own blood vessels. It can also reduce side effects of chemotherapy such as lowering of the white blood cells.
Chemotherapy and immunotherapy may be given in combination with other chemotherapy and immunotherapy, by itself, after surgery or with other forms of treatment such as radiation. Your doctor will develop a treatment plan based on the type, stage and location of cancer and your general health.
