base of tongue is not visible because it's back in the throat so it would not be that type of concern.

i'm a caregiver but i hear over and over here if something is around more than 2 weeks, you might want to get it checked out but it's not cancer until it's diagnosed as cancer.

for the record, my husband had a stage 4a back of the tongue cancer...not a good prognosis but over a year later, you would not know he had cancer. going through treatment was awful but he has survived.
