I do not show any signs or symptoms. Instead, I just want accurate information on the subject of HPV in a sexually active individual. I would like to know its role in throat cancer. Yes, I know it can cause it, but I would like to know more regarding numbers. Is it rare? What percentage of people get throat cancer from it? Also, I am 30 years old and have smoked half a pack in a day from 19 to 26 years of age. I have quit now and have not smoked in the last four years. I know the body naturally fights off HPV with the immune system. But, I damaged and lowered my immune system while being very sexually active (orally) with women. Should I be worried? I know I am young and have stopped smoking but just asking.
