Hi, Dan:
Congratulations on your retirement from your law enforcement position.
I retired from a desk job in 2005 at age 62, and a year later my AN was discovered. Surgery and radiation naturally followed. I always figured that in a sort of perverse way, that worked out rather well as I never had to deal with work issues or apply for Social Security Disability and the attendant hassles involved.
Best of luck pursuing Social Security Disability status. I expect you'll win an 'award' (benefits) but it takes time and determination. My wife has been on it for 10 years and it took well over two years for her to finally prevail, as it were. Fortunately, she also has disability coverage from her former employer and is still technically employed so we can retain her excellent medical coverage, allowing me, as a covered spouse, to avoid Medicare, even though I'll be 65 in 2008.
At 44, you may get bored with retirement but I haven't, yet, so go for it - and enjoy! You've earned it.
Jim
