Welcome to healthcare magic for your health concerns I am Dr Fahim and I will be looking into your problem I have gone through your question and understood your problem and concerns. Increased proclactin levels that are caused by a tumor as you are reffering to, is called prolactinoma. You are concerned whether surgery is the only option you are left with. For your information, We have two treatment modalities for this disease, Medical and surgical. In Medical treatment we give oral medications that decrease the production of prolactin, so eliminates the symptoms. It can also shrink the tumor. So in large number of patients’ only medications treat their disease. However, long-term treatment with medications is generally necessary. Side effects of these medications include nausea and vomiting, nasal stuffiness, headache, and drowsiness. If medication shrinks the tumor significantly and your prolactin level remains normal for two years, you may be able to taper off the medication with your doctor s guidance. However, recurrence is common. Don t stop taking your medication without your doctor s approval. Surgical therapy is only reserved for patients for whom medications does not work or they are unable to deal with the side effects. Surgery removes the tumor and thus also relieves pressure on the nerves that control our vision. They are two surgical operations available Trans-sphenoidal surgery and Trans-cranial surgery depending on the size and extent of the tumor. I hope my answer will help you. Do rate it if you like it.
