My dad apparently had a melonoma on his nose. He and his wife, my stepmom, kept insisting it was just a blood vessel which was swollen due to a little dog bite twenty years ago. Anyway, when I arrived on the scene we got it removed, but according to my doc, b/c it was on his nose it could easily spread through the sinus into the brain. Yes, I definitely think it contributed to his aggressive behavior. We have a lot of BiPolar Illness in our family. Some of us go for treatment, some don't. The ones that don't are the hardest to deal with. I also think it's a way of staying disconnected but avoiding feeling guilt. If I am "the bad guy," it's a convenient excuse to stay away. Thank-you for helping me sort through that.
