This is a weird one for you all For about 10 years I had a small red and sometimes slightly painful sore on my right tongue. I've seen a doctor, and dentists, and the best diagnosis I got was Canker Sore. For a while, sometimes worse (caused by food), sometimes it got better for months too. Sometimes pain, sometimes none.

Recently, a patch turned White. So I saw a doctor again, and then specialist, and was told it could be cancer. To be more precise, the diagnosis was: "small area of homogenous
leukoplakia with some surrounding erythroplasia. This could well be a lichenoid reaction to the amalgam."
Well, I have just had a Biopsy and am now awaiting the results.

The puzzle for me, is it ever heard of for a 10 year sore on tongue?! From what I've read on the internet, such sores generally progress to cancer aggressively. Any insights/experiences would be appreciated?

The specialist remarked I would've been dead by now if untreated cancer, he then rightly ordered the biopsy and wants it checked.

Thanks
