What do you suggest if my husband is getting ready to do weeks of chemo/radiation for tongue/throat cancer. what can i do to help?

Support: Encourage nutrition & hydration. Keep him swallowing, as the more he does, the sooner and more likely he will get back to eating normally. Encourage him to not miss treatments; tumor cells grow back on missed days, especially in the most difficult last weeks of treatment. Watch out for fevers; report them to his docs. Stay patient; this can be very tough but he will hopefully come out cured.
