Hi Laura

Robs cancer was first detected in the fluid they withdrew from the sub-mandibular swelling under his chin.that was a week before his biopsy.so really we knew he had cancer before the operation to biopsy his tongue.the site where his swelling has occurred is quite a common place for the beast to rear his ugly head again.As for the rest ,i would schedule a sooner appointment and get them to spell things out to you,in language that everyone understands,and try to remember ,until all the results of tests are in,this is just an opinion based on experience.How did you get on with this doctor when our dad was first sick?
