Hormone Changes after surgery for Oligodendroglioma grade II?

Has anyone, namely female, experienced any types of hormonal changes since surgery? My hair is much more wirey. I am blonde, no European background and suddenly I have whiskers. Blonde but wirey and not just one or two, thicker to the point that my dad noticed! My husband jokes and says that the hair along my scar is trying to grow back but has become ingrown and is coming out my chin instead. Some people can find fun in everything. Needless to say he was kicked out of the bathroom with the door slammed in his face!
