Depends: We don't have expiration date marked on our body. How long one will live will depend on many factors. It will definitely depend on the biology of the cancer, the response to therapy, your husband's overall condition etc.At least from studies we know, on average, stage IV colon cancer's survival is approximately 36 months or so. One may be shorter while other may be longer. D/w your oncologist.
