Thank you Andrea for your info. I had no idea what caused a polyp. My sister had them removed from her vocal cords. Her voice had been going up and down for some time and she was having difficulty swallowing. After they were removed, she's fine. Yes, you are right, I am more concerned than she is. We were never particularly close since we were raised apart. We did stay in touch with one another, however we haven't talked for months now. I don't think that she can handle ME now. She avoids me and continues to stick her head in the sand. I know a few others that avoid me now too, don't they get it...cancer is not contagious!
