34 years old and had a spot in the middle aspect of my left lateral tongue. Oral surgeon dx it as a non-healing Ulcer. He removed it and sent it off for biopsy. My question is are all non-healing Ulcers usually cancer. He told me I should not worry but everything you find about non-healing ulcers of the tongue point to cancer. I was wondering if anyone else has experience this and advice of what you have been through.
