Even if recommended by your doctor, it is always your choice whether or not to have this surgery. But, it is important to understand the possible results of this decision.
Although no one can truly predict the outcome of your specific situation, it is possible that the current problems you are experiencing may get better, stay the same or worsen. As a fibroid grows larger, there is a possibility that new symptoms will develop.
However, if you are going through menopause, or will be soon, your symptoms may get better or go away without surgery. The final decision to have or not have surgery rests with you, but all concerns related to this decision should be discussed with your doctor at length. Then you and your doctor can come up with a treatment method that is comfortable for you.
