It sounds strange because we expect the sense of taste to return gradually. I met a guy at my support group who regained his taste two years after radiation quite suddenly but says he has very little appetite. I think he had tonsil cancer and it seems that tonsil people have radiation where it hurts the most.

This used to puzzle me because the tonsil - in my childhood - was a completely dispensable part of the body and one that doctors frequently removed in the 1950s and from very young children.

I've tried to do some research into taste bud recovery but haven't found a site which presents the information in a manner I can understand.

My own taste started to return 10 days after radiation ended and is now almost 100%. Savoury foods are often too salty and sweet things taste better, alas. I can even differentiate the different fruits in a smoothie.
