In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain.

The goal for this procedure is the same as open surgery: to remove tumors, and also tissues and lymph nodes if needed. Instead of one large cut, the surgeon makes several small ones. They put a tube with a tiny camera into one cut to see inside your body, and tools into the others. This is called laparoscopic surgery.
