Chemotherapy,

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cells in your body. Chemotherapy is most often used to treat cancer since cancer cells grow and multiply much more quickly than most cells in the body. Many different chemotherapy drugs are available. Chemotherapy drugs can be used alone or in combination to treat a wide variety of cancers. Chemotherapy is also used to prepare you for other treatments. It could be used to shrink a tumor so it can be surgically removed, or to prepare you for radiation therapy. Besides treatment for cancer, chemotherapy may be used to prepare people with bone marrow diseases for a bone marrow stem cell treatment, and it may be used for immune system disorders.
