Treating cancer with chemotherapy, targeted therapy, radiation therapy, or a combination of therapies, the purpose is to kill cancer cells and to reduce the size and spread of the tumor. When the signs and symptoms of a cancer partially or completely disappear in response to treatment, it is called remission — a period during which the disease is under control. A remission, however, is not necessarily a cure.
Cancer is a serious disease and all of us are at some risk of having cancer sometime in our lives. But a diagnosis is not an automatic death sentence. More than half of all people who get cancer this year will be alive five years from now. Aggressive treatments, improving medical knowledge and experience, and modern medications are increasing the average survival rates every year and allowing people to lead normal lives.
