I am a 60 year old hispanic female, I m 5 1 and weigh 170 lbs. I have a history of cancer, colon in 1996 and lung in 2005. I also have a strong history of cancer in my immediate family. While at the dentist, I noticed a skin tag, about the size of a watermelon seed on the left back side of my tongue. It doesn t hurt or bother me at all. He referred me to an oral surgeon for further evaluation. Should I be concerned ?
