My husband was diagnosed late 2015, He is part way through his treatment, which has so far been interupted twice due to infections. He seems to find it hard to know when he is feeling poorly due to the Chemo, or because he actually is ill due to an infection. We do not talk about his treatment. He doesn't want to. I respect that, but feel pushed out and isolated. I know that this is "HIS CANCER" but how do I help
