If there is no history of trauma (such as biting your tongue on accident), the best thing to do is to see your dentist or oral surgeon for them to perform a biopsy.
The whilte fleshy growth appears to be a overgrowth of papillae. Could it be reaction of the papillae to drugs or food poisoning. I noticed it when I checked my tongue for the tingling and sensational feeling and numbness I have due to fish poisoning. Grateful if you could help again.
Its possible that it could be a reaction to drugs or food poisoning. Without seeing it, its a little hard to say. You can observe it yourself for a few days and see if it heals up and the pain lessens. If it worsens or the lesion grows larger, I would recommend seeing a dentist right away. Usually with cancer in the mouth, its not painful. Sometimes it is though. If you have any high risk activities such as smoking or frequent alcohol consumption, I would get it checked sooner than later.
Thanks very much for your quick response.
You're welcome. Hope everything turns out good!
