Welcome to OCF! Im very sorry you are going thru this. Hopefully whatever your sore turns out to be not cancerous and that its easily fixed.

Please do yourself a huge favor and avoid Dr Google like the plague. The things you have written are NOT correct!!! It could be any number of things besides cancer. Leukoplakia does NOT always turn into cancer. Also, cancerous tumors do not come and go and sometimes get worse then get a little better. Thats not at all how a cancerous tumor presents itself. Everybodys different and will respond to things in their own unique way with medicines, procedures, recovery, etc.

Any sore a person has inside their mouth that does not heal on its own within 2-3 weeks should be checked by a professional. By professional, I mean an ENT who specializes in treating oral cancer patients. Dont panic by my advice to seek out someone who specializes in oral cancer. You do NOT want to get checked out by an ENT who primarily puts tubes in childrens ears. If a biopsy would be necessary, that type of ENT should have seen many spots/sores/etc both cancerous and non cancerous and have the experience to know what needs a biopsy and what doesnt. Even the most experienced doctors still must do a biopsy and have it examined by a pathologist before knowing for certain what something is. Try your best to ignore what the doctors told you about it being cancer. At this time, its just a guess. Right now, until that biopsy comes back with a cancer diagnosis you have NOT been diagnosed with anything. Do your best to stay super busy with positive things until you can get the test results. By staying busy it will help the time pass easier.

If you use tobacco in any form, drink alcohol or use mouthwash that contains alcohol please stop using those things right away. Its possible your sore is there from being irritated by something.

Hang in there and please keep us posted how your results turn out. Hopefully its not cancer but if it would be you are in the very best place to get info and support. Good luck!!!
