I'm new here also. I'm hoping someone can give me some insight into my issue.
First, I am undergoing extensive dental work right now. The hygienist had checked my tongue, etc. for any issues about a month ago and nothing was found. I have had a small bump I can feel with my tongue on the lingual frenulum below my front teeth. In the past it has somewhat gotten a little swollen. I could press on it and it would go down but sometimes swell again. Recently I punctured it and it bled a little and now is white in that area (I'm assuming it's healing). I'm using salt water rinses to heal the area. Does anyone know what this could be? Could it be a blocked duct? I'm hoping it MAY be something simple. I have smoked for a long time...yuk!!! Have tried to quit unsuccessfully. I don't get a fuzzy feeling w/the dentist doing my work right now, so I'd rather pursue other avenues for help. Thank you.

Also, the little bump doesn't always seem prominent...just sometimes.

This has been noticeable to me for a few years now.

Also, if anyone has any input, I would really, really appreciate it as I'm quite nervous about this. Thank you!!!!

First, calm down! Any sore that comes and goes is likely not cancer. If a sore has been in your mouth for at least 2 weeks and not gone way then its time to get checked by a professional. I would suggest seeing an ENT (ear, nose and throat doc). I would doubt that a cancerous tumor would be in your mouth for years without you having any other serious consequences.

Smoking.... you probably already know what Im going to say. QUIT!!!! Let this be your wake up call. There are hundreds of chemicals which are irritants added to tobacco products. Any one of them alone could be whats bothering your mouth. Many of these irritants are known cancer causing agents. I am a former smoker myself. I quit cold turkey when I was on my way to get a feeding tube. Stupidity is why I am now disfigured and live a very different life than before I got sick. I almost died all because I smoked. Dont let this happen to you. Call 1 800 quit now or check out the CDC's Tips From Former Smokers website. You can see what I look like and why I am telling you to quit. I wouldnt wish oral cancer on my worst enemy!

Thank you for responding. I have read several of your posts, and you are a very kind, compassionate person. You are helping many people.
I was concerned about the white part right now. I think it may be healing from my puncturing the area (stupid as I am!!). I couldn't figure out why a small bump would become prominent and then subside when pushed on it. Believe me, your posts about quitting smoking are hitting home. But, you are also making me feel somewhat relieved. I guess I need to wait a while to see if the white disappears then. Thank you for all your time and effort on this forum!!!

Can someone give me insight into the bump that will go down w/pressure?

Also, the white area is somewhat going away (I think some was from salt water). There is now one oval (round) white spot right in the center with a translucent bubble in the middle. Any ideas?

Sometimes tastebuds swell and such. Try not to worry,

I don't think it's tastebuds because it is on the lingual frenulum, not the tongue.
Right now the white has subsided, I can scrape it off with my finger...so probably from salt water. But there is a small round bubble there at the very end of the frenulum near my gum under the bottom teeth. I was hoping Brian Hill might be able to help as posters have indicated he has a lot of dental knowledge. Thank you!
