Hi, My Cancer was in my jaw not my tongue,my first biopsy was negative for cancer, took a deeper one and got squamous cell carcinoma.What I had has a deceptively benign microscopic appearance.I have referred to this in other posts hoping someone with more medical knowledge would take on the fact that this happens. It just happened to my neighbor who went in with a Stage1 small lump in her breast and they found a second mass and removed 15 lymp nodes.Mark or Brian want to take this on? The shock to you must have been terrible. Being told once is enough, twice is the pits. I have a friend who has been fighting cancer of one type of another for 36 years, he gave me the advice of; Let them do what they have to get rid of it , but you just get on with your life , he says how long will this take , and when can I get going again! He is a brave ole soul. Good Luck to you. gnelson
