There are many reasons to have surgery. Some operations can relieve or prevent pain. Others can reduce a symptom of a problem or improve some body function. Some surgeries are done to find a problem. For example, a surgeon may do a biopsy , which involves removing a piece of tissue to examine under a microscope. Some surgeries, like heart surgery , can save your life. Some operations that once needed large incisions (cuts in the body) can now be done using much smaller cuts. This is called laparoscopic surgery. Surgeons insert a thin tube with a camera to see, and use small tools to do the surgery. After surgery there can be a risk of complications, including infection, too much bleeding, reaction to anesthesia , or accidental injury. There is almost always some pain with surgery.
