I dont know why it would mater, but this is the info that I have from my 1st oral cancer experince.. squamous cell carcinoma, tumor extends into underlying muscle.. mar 17 2003 procedure performed left anterior partial glossectomy with primary reconstruction.I did not have radiation/chemo.. I was followed up every other week for 6 month, then to everyother month for the rest of 2003 and in 2004, after my one year mark, was seen every 3months until jun of 05 was supposed to have bio 1st week of jul, but there was an earthquake, now waiting until this thurs for bio.. it could be somthing else. and I do hope that my plastic surygen and theripst are incorrect,both have made me swear not to leave the ent clinic until a bio is performed..does this help you.. as to what stage, I never asked.. I didnt think that it would matter. I would either make it or not..
