I don't know which medication yet. Is 6 chemo treatments a lot? I'm sort of confused again. They said his tumor was Stage 4, T2a (I think ) and N0. They said they removed 19 lymph nodes, none of which were positive. They said it didn't invade lymph tissue or blood vessels even though it had many months to do so. They got clear margins, but one finger of the tumor extended close to the margin but when they scraped the tissues left in him they found no cancer remaining, so Dad was in a gray area whether he would even need chemo. It seems like a lot to me. They said because it had effected the bone, he'd definitely need radiation. Does radiation and chemo seem right in this instance?
