Where are you going to be treated Melissa?
Have you been seen by the oncology dentist?
Did you talk to the oncology Dietician? Have you discussed a PEG feeding tube with the team? Make sure you eat up a storm between now and the radiation starting. You need to increase your caloric intake, most undergoing this lose about 20kgs. Enjoy the taste of everything you most enjoy as your taste buds will take a hit for quite some time.
Gather a support team of friends and family to help out. To drive you to appointments, to help with the kids and general household chores, as well as to just be there for you.
Look after yourself,
