So many things 'set in' after you are retired. 1 in 2 men will deal with cancer as will 1 in 3 women. Now, I may have gotten those odds backwards, but either way, the odds are pretty good you'll get it.
The treatments would wipe you out without coverage. This is old info from 2007.....
"the average cost of treatment for individuals experiencing external beam radiation therapy is $24,204 during the first six months of treatment, with each additional six months of treatment past the first resulting in average extra costs of $3,222. This includes the cost of medications, outpatient visits and hospital stays incurred in connection with the treatment during the initial six-month time period."
Chemo can run $10-12,000 a round.........and when you are scheduled 16-18 rounds, you may find some time for fun in your retirement, but you'd have no money.
