I’m a retired RN. Everyone should get a thorough physical every 1-3 years. When I worked on a medical floor, it was common to admit these tough old buzzards, often farmers, who hadn’t seen a doctor in decades, sewed up their own wounds, supposedly “never sick a day of my life” etc., but were now full of cancer. They’re tough alright, never complain, even of things they should, but if they’d just had a physical once in a while, they could have found the disease before it was terminal. And just for the record, I was a nurse for almost 30 years, and I couldn’t count on one hand the doctors I dealt with who were in it for the money. (Not saying you think that, but many people who avoid doctors, do.)
I confess, I don’t trust doctors. As for cancer... I have the sinking feeling that once you’ve got it, you’ve got it. Treatment may beat it back for a little while (at a very high cost, both financial and physical) but it’s coming back, probably soon, and this time it will get you. JMHO.
