Thanks for your inputs and support I had the removal done todsy they put me out for it and it appears he went as far ss the original biopsy 3 mm down the whole left underside of my tonge. In alot of pain now. Feel lucky it appears to have been caught early. Thisd particular dr is very experienced using a laser he was head ent at duke and Johns Hopkins now has settled in upstate New York. Three years ago the ents two dr's said the saw a large patch of the very flat HPV cells which went the entire length of the left side of my tongue and down into my throat. I also had and endoscopy recently and was diagnosed with eosoniphilic esophagitis. Also had am eosnophil polyp removed a few years ago. Would it have been better for them to remove or test for HPV and then monitor.Three years ago they did not even tell me that HPV could lead to cancer and they did not recommend follow up appts. at the time. Recently my dentist saw the leukoplakia and said I definitely needed biopsy. Seems like there should have been more diligent follow up. Seems like it would have have been better to remove tissue when it became displasic? Not sure on alot of this? Current plan is to follow up with results of tissue in a few weeks. IT will be analyzed by Beth Deacconess hospital in NYC. One thing tthe dr. said is that the line is fine between severe dysplasia and micoinvasive carcinoma. That this imaginary line is used and different pathologists have different definitions. Some actually define micoinvasive cqrcinoma as almost filling of fillin line. Any ideas? Any feedback and advice would be greatly appreciated.
