i chew tobacco about once a day for the past year. recently, the left side of my tongue doesnt really hrt but rather aches some times. Also there are several pink colored lumps (small) on the very very back of my tongue, unreachable by a toothbrush. wondering if you have any idea what this is or if it is early signs for cancer . i dont have luekoplakia or anything like that right now which is why i thought it was weird that just my tongue hurt. my wisdom teeth are on their way in aswell i do not know if that would effect anything
Hello and thank you for your question.  If the bumps are on the top of your tongue, chances are they are to circumvallate papillae which help in taste.  If they are on the sides of your tongue then chances are they are the foliate papillae.  It is highly unlikely to develop oral cancer from one year of use, but does increase you chances of developing it.  I would recommend discontinuing the use of chewing tobacco and use substitutes like Capitol gum.  Your wisdom teeth can contribute to the pain, and you should probably be evaluated to have them taken out.  See if the pain stops after discontinuing the usage of the chew. It may take two weeks for the tissue to heal post exposure to the irritant. Best wishes and good health.
