Overall, he is relatively healthy with the exception of some mild cognitive impairment. He is scheduled to have surgery in 6 days for abdominal hernia repair. How can I know if this surgery is truly necessary at his age? I don't trust my mom to make this decision as she can be an "alarmist." A Gastroenterologist has recommended this surgery but how can I trust him with "medicine" being such a big business now? Thoughts please? Do the risks of surgery outweigh not having surgery at all? From what he has said, he's not in any kind of major pain. Couldn't this just wait until symptoms increase? I'm so concerned and need help figuring this out. Thank you!
