After having squamous cell carcinoma removed from my forehead almost 2 years ago, I look at every little thing on my skin suspiciously.
Never will wait as long as I did with the SCC but will go in if I question anything.
Glad under your tongue was benign.
My husband has Squamous cell on his cheek and bottom lip. I told him it was a good thing he had a big mouth because they cut a big hunk out of it.
