My experience is similar. I was very healthy until I was diagnosed with stage III colon cancer earlier this year. (This was after a completely clean colonoscopy 3 years prior.) If I hadn't had insurance, I would be on the hook for $366,000, and that's with 5 more chemo cycles to go. The total will probably be about $450,000 by the end of the year.After reading several replies of folks saying they're healthy and aren't worried about insurance. My story, I'm healthy workout no issues and then one day simple blood test indicated possibility of cancer. Biopsy indicated stage 2 cancer and underwent surgery. Thankfully I had Insurance otherwise I would have been on the hook for about $70,000 worth of healthcare. Don't fool around. You can be going great and carefree one day and the next day your world falls apart. Get adequate insurance and get annual check-ups cuz if I hadn't gotten an annual check-up I wouldn't be posting this right now. BTW, I was just 50 when I was diagnosed.
