Might want to leave that choice to the people having to decide. My friend had her whole lower body opened in an abdominal exenteration surgy. She had multiple abdominal organs removed, vagina, as well as vertebrae. She had to relearn how to walk, and now has an ostomy bag and catheter. Some people turn down the surgery because they would rather die. My friend is happy she did it. Some pain is worth getting to spend extra years on this planet. That's what most terminal cancer patients want. More time to get to the next treatment, to hopefully find a cure or long term solution. Living with stage 4 cancer is not all pain and suffering. Most people are just living their lives.
