Will, welcome to the forum. I’m sorry you have to join our circle of friends, but I know members of the forum are there to help you through your treatment.

Radiation and chemo are the standard treatment for base of tongue cancer. The chemo is a radio-sensitizer and it helps to mop up any stray cells that manage to escape the radiation. At our hospital (I’m in Canada), it is standard practice for patients to get a PEG tube, usually in the third week of radiation treatment. If you’re already having difficulty swallowing, you should look at asking your medical team to schedule you for an earlier appointment. It won’t do for you to lose a lot of weight before your treatment even begins. During treatment it is extremely important for you to stay hydrated and keep up your calorie intake. I’m sure ChristineB will come along soon and talk to you about intake.

If you are looking for low carb liquid food for the day before the PET, what about making some homemade soup. That will be easy and you will know exactly what goes into it?

Please keep us posted and do ask if you should have any questions.
