Surgery is a medical procedure which involves cutting and restitching of tissues. Traditionally, surgery was performed by cutting the tissue with a scalpel, and later closing the tissue with stitches. Today, however, Laser Surgery cuts the skin using a laser, and some wounds are closed without stitches.
There are three types of necessary surgery: emergency, urgent, and elective. Emergency surgery is extremely urgent, and minutes count. Urgent surgery is still quite urgent, but can be put off for a few hours. Elective surgery can be put off for some time.
