Yes, there are treatments for throat cancer.
The treatment will be dependent on exactly what part of his throat is affected, how advanced it is, etc. There is surgery, chemotherapy, and radiation treatment.
Many people have had throat cancer and completely recovered.
You didn't mention your Mom...you may want to ask her these questions, or you may even want to ask your Dad to let you know what's planned, etc. It all depends on how you react...are you better off knowing everything? Or are you the kind of person who doesn't want to know every detail?
I would advise letting your folks know what you're comfortable with. Yes, this is very, very scary, but a positive attitude can make a world of difference...not just for the cancer patient, but for the family, too. If it gets too much for you to handle, and you can't talk to your folks, ask them if you can get some counseling, so at least you'll have someone to talk to about your fears.
And, of course, you can always talk to us!
