Treating Cancer
If a person is diagnosed with cancer, there are a variety of treatments. There are three common ways to treat cancer: surgery, radiation, and drugs that destroy the cancer cells.
When a cancer is detected before it has spread to other parts of the body, surgery is usually the best treatment. If doctors can completely remove the cancerous tumor, a person may be cured. If, however, the cancer has spread or if the tumor cannot be removed, doctors may use radiation. Radiation consists of beams of high-energy waves. Fast-growing cancer cells are more likely than normal cells to be destroyed by radiation.
Chemotherapy is another form of cancer treatment. Chemotherapy is the use of drugs to treat a disease. Cancer-treatment drugs are carried throughout the body by the bloodstream. These drugs kill cancer cells or slow their growth.
Scientists continue to look for new ways to treat cancer. If scientists can discover how the cell cycle is controlled, they may find ways to stop cancer cells from multiplying.
