SURGERY

Surgeries may be done for different reasons:

• Relieve or prevent pain.
• 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.

Technologies and innovations help the surgical process. For example, 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.
