In addition to what everyone else has already said, you’re talking about grandparents. Some people are not healthy enough to undergo general anaesthesia or general anaesthesia for a long time for a long complicated surgery trying to remove all the bits while maintaining the organs. The liver is needed to recover from general anaesthesia, if they remove most of it he may never wake up.

You also don’t need a colon at all to live, some people have the whole thing just removed (and a colostomy bag instead). You do need a liver to live. The tumour could be on a key part of the liver that can’t be removed and have the liver still functional.
