Hello Emma sorry to hear about your Dad . I have stage 4 lung cancer too . I have been on immunotherapy for 1.5 years and also went through the dexamethasone thing . The reason they gave it to me was to make me eat I had lost a lot of weight. I don't know why they are giving it to Dad but when you finally get off it all things go back to normal in my case anyway.
