Meg,
I had an abnormal spot on the left side of my tongue that gradually got larger and eventually became painful. Over the course of a couple of years and numerous office visits, I was told by three different doctors (dentist, GP, oral pathologist) that it was nothing to be concerned about because I had never smoked. I finally found an oral surgeon who recognized the symptoms, performed a biopsy and referred me to an oncology team that concluded I needed both surgery and radiation. The surgery involved removing a portion of the left side of my tongue, along with many lymph nodes in the neck. Radiation consisted of about 7 weeks of external beam treatment followed by a radiation implant in my tongue for about 30 hours. Long-term effects have included some impact on my speech, and dry mouth (from radiation) that can cause difficulty eating and swallowing from time to time and requires frequent dental checkups.
