Hello, Faith. Thank you for writing to us.
People with advanced lung cancer often feel very fatigued and don't feel like eating. These problems can sometimes be very difficult to manage. With effective pain medications, it should be possible for your husband to be comfortable. I can't know how long he will have. His doctor might be able to give you his opinion on this. I'm sure the love and support of you and your family will help him for whatever time he has left. And I hope that love and support will extend to you as well.
