My wife had brain surgery to remove a tumor of similar size on July 6. The surgery went well and the surgeon said he got all of the tumor he could. Her recovery from the surgery was remarkable as it was on July 6 and she left the hospital on July 8 after on two nights there. Her recovery at home was uneventful and she had little pain which was managed by meds for a week or so before she was off those and onto over the counter pain meds. The surgery itself was not extremely difficult for her. The diagnosis of the type of tumor is the most important point in my estimation, as that dictates the follow up care. The direction of the surgeon as far as what they feel they can remove and what side effects are the important factors in the decision. In my wife's case, there were no real side affects from the surgery itself. If you are not confident with what the surgeon is telling you get a second opinion before proceeding. Wishing you success and may God bless you.
