Can you tell me exactly when is it justifiable to have hysterectomy?

Depends.: Hysterectomy can be used to treat a variety of problems. Most commonly bleeding, pain, fibroid tumors or prolapse although their are many other reasons that a woman may have a hysterectomy. Their are usually alternative treatment options and the pros and cons of each treatment should be discussed with your doctor. Never hesitate to get a second opinion if you are uncomfortable.
