Md Anderson is top notch - if I lived in the states - (I live in Canada and was treated at princess Margaret - also top notch) I would go there - particularly after a second primary. Oral cancer can be deadly and aggressive - pick the best plac that offers the best treatment outcome. As others have said you can have more than one round of rads - I know someon who's had 4 or more recurrences and her RO has found a way to give her rads each time. She's at md Anderson as well. She's finally got an all clear. Hope your insurance approves!
