I find this news very interesting, and as I said in a recent thread about
melatonin, I've always suspected that my then-untreated sleep apnea had a lot to do with my developing prostate cancer. This study, reported today, indicates the likelihood of a link between fragmented sleep (e.g., sleep apnea) and the development of aggressive cancers.

A whole lot of men have untreated sleep apnea. They shrug it off as snoring or something else, but only a sleep study can really determine if it's apnea. Often, though, a spouse can tell if his/her mate has apnea by noticing that they hold their breath for extended periods of time while sleeping. They probably snore loudly, though that's not a given. My wife used to time me, and would tell me that I held my breath for over a minute frequently during the night. Occasionally, I would awake gasping for breath and in a panic. After a sleep study and with the use of a CPAP machine, I sleep great, don't snore, and wake up refreshed rather than exhausted from a night of tossing and turning.
Sleep apnea is serious. It puts stress on every organ. And now it appears that it may be a contributor to the development of cancer and cancerous tumors.
