What type of cancer he has?
Was he recently diagnosed?

Cancer is a disease which needs to be tackled with understanding and comfort. It is a situation where your grandfather needs your warmth and that special touch to make him feel better as the medicines cannot work this way. Cancer patients at eHealth Forum can share about themselves, what they feel, their thoughts, their experience and their problems related to it. I think this will help your grandfather to be more relaxed and write and share the things he is concerned about.
