"The prostate cancer finished toying with me on October 6, 2017. I was 66 and glad to be done with the damn disease," Mr Mooney wrote.
Surprisingly, his one lament was wishing he had been able to do more work as a journalist.
"I wish I had done more work as a news reporter. Written better stories. Made more and better contacts. Skipped some of the easier pieces and done more in-depth stories. Spent more time on foreign stories. Been a better editor," he wrote.
Mr Mooney's final wish: "In lieu of flowers, donate to a favorite cause."
