As a patient, you are entitled to a full discussion with your surgeon about the potential benefits -- and risks -- of an operation before you give consent to the treatment. "Patients certainly shouldn't feel intimidated or concerned about asking questions. It is ultimately their health that is at stake," says Sally Bean, a Policy Advisor and Ethicist at Sunnybrook Health Sciences Centre. In my experience, most surgeons are quite happy to discuss those types of things with you." So, to answer your question, it is okay to ask a doctor how often he or she has performed the procedure.
