People have surgery for many reasons:
- to relieve or prevent pain;
- to ease a symptom or improve how part of the body works;
- to find a problem — for example a biopsy, which removes a piece of tissue to study under a microscope;
- to save a life — as some heart surgery does.
Smaller cuts: laparoscopic surgery
Some operations that once needed large incisions (cuts in the body) can now be done through much smaller ones. In laparoscopic surgery, the surgeon passes in a thin tube with a camera to see inside, and works with small instruments.
Risks
Surgery can bring complications:
- infection;
- too much bleeding;
- a reaction to anesthesia;
- accidental injury.
And there is almost always some pain afterward.
