Hi. My father in law has been diagnosed with stage 4 cancer which started in his eye but is now in his liver and terminal.

My father in law has received one immunotherapy treatment so far with another in a week.  He is feeling very tired and lives alone.  He is fiercely independent.   Very little discomfort at the moment but fatigue and loss of appetite is there.  He looks well other than that.   Can he cope on his own?
