Hi KMD.
Don't be alarmed by my signature. You won't likely be in my shoes. I'm glad you are getting it biopsied so that you know what it is for sure. I'm 34 (was 33 when diagnosed) and I too didn't have the typical risk factors Although I did smoke on occassion in college and little after but haven't at all since 2001. I oly drink beer and wine and not heavily. I saw a dentist and 2 different drs before finally getting to an ENT who took a biopsy..
Tongue cancer can be caused by many diff things. Another patient of my oncologist who also has tongue cancer thinks she got it from a tongue ring she had- I've read that after repeated trauma to an area the skin cells can sometimes come back cancerous. I think that is what happeed to me because I tested negative for
HPV but had tons of dentistry as a kid and teenager. Who knows.
Anyways- don't worry about all of this unless the results are cancer.I'm hoping for a negative biopsy for you.
Good luck and I hope that sore goes away!
Have a fun weekend.
BTW I am leading a full happy life again after a crazy surgery and intense cancer treatments
