The following year, about the same time, my sister suggested he go in for a check up, and so he went in for a check up and he came home and she said, "Well, did they check to see how your colon was doing?" He said, "no, no," and having a medical background she said, "eek, you need to go back in there, now." Actually, he should have gone several times throughout the year to be monitored but that hadn't been done so he went back in. They found the cancer was there, that it had spread.
