Cancer Facts:
How is Cancer Treated?
The four major types of treatment for cancer are surgery, radiation, chemotherapy, and biologic therapies. You might also have heard about hormone therapies such as tamoxifen and transplant options such as those done with bone marrow.
What Is Cancer?
Cancer develops when cells in a part of the body begin to grow out of control. Although there are many kinds of cancer, they all start because of out-of-control growth of abnormal cells.
Often, cancer cells travel to other parts of the body where they begin to grow and replace normal tissue. This process is called metastasis. Regardless of where a cancer may spread, however, it is always named for the place it began. For instance, breast cancer that spreads to the liver is still called breast cancer, not liver cancer.
Cancer is the second leading cause of death in the United States. Half of all men and one third of all women in the United States will develop cancer during their lifetimes. Today, millions of people are living with cancer or have had cancer. The risk of developing most types of cancer can be reduced by changes in a person's lifestyle, for example, by quitting smoking and eating a better diet. The sooner a cancer is found and treatment begins, the better are the chances for living for many years.
Treatments, Cures:
Also, finding one all-encompassing cure for cancer is unlikely because cancer is actually many different diseases. For several forms of cancer, cures are already available for the majority of patients.
Only a few decades ago, fewer than one in 10 children with leukemia survived 10 years after diagnosis. With modern chemotherapy, the cure rate for these children is almost 80%. Examples of similar progress include Hodgkin's lymphoma, bone and kidney cancers in children, and testicular cancer.
