I am a 35 year old female having issues with my mouth/throat. Symptoms are a feeling of a piece of food caught at the back left of my tonue or tonsil area and I recently found a small smooth firm lump on the lower left gums behind my premolars almost at the base of my tongue. I have seen an ent over the course of a few months and he found nothing suspicious and no changes to note (although he did not feel the small lump in my mouth as I just discovered it). He performed the nasal scope twice and also sent me for a neck MRI which was clear. I will see a dentist tommorpw and have them check the lump below my gums but I have a major cancer phobia/anxiety issue and I guessI just want a second opinion of what could be going on. The dr I saw said there is no more tests he can do and that I only need to return as needed but since the weird feeling in back of my mouth is still there I m still worried. Does a clear MRI mean oral cancer has been ruled out?
