I think you should see the dr in Philly. If he says you're okay accept it but definitely check the area weekly just to make sure it doesn't progress. Sometimes drs miss stuff. You know your body best. If something is abnormal make sure you push until you get an answer! My first biopsy was negative. The dr. said the area under my tongue was all red - he didn't know where to take. Sample from there was an internal lump there just no visible sore. That biopsy was negative - the one I had in Dec was not. Dr.s are knowledgeable but not foolproof. So just keep an eye out. Take care and hope you don't have to be here!
