It destroys these cancer cells and stops their growth. Chemotherapy affects some healthy cells, and this effect appears in the form of side effects, but healthy cells do it repairs itself after the end of treatment.<br /> Some chemical drugs have a stronger effect if used with other drugs, so chemotherapy is often used in a therapeutic "system" consisting of more than one type of those chemical drugs, and chemotherapy is used to achieve a number of goals depending on the type and stage of the tumor.<br /> Abnormal cells are cells that grow outside the control of the body, and among their characteristics are that they multiply rapidly and rapidly reproductive cells are more vulnerable to the effects of drugs than most natural cells.
