Hi Malvika,
Yes, it is actually a very common procedure and is relatively safe. However if performed incorrectly or in an unsanitary environment there can be complications and risk. The risk involved are usually minor, but in very rare occasions death has occurred, around two people out of ten thousand. There are some things that one can do to lessen the chances of complications, such as:
*Choose your doctor carefully
*Check his background
*Physical examination before to make sure you are healthy enough to have the surgery
*Keep wounds clean after surgery
*Take all antibiotics prescribed.
