The problem with this one is not TM, it's the person who reported the testing. I'm sorry but just because a person is an athlete doesn't mean personal information like being tested for cancer should be in the public domain.
Once in a while I have to run clinical trials. When conducting them, if I give away someone's personal medical information I can be arrested because of the hipaa violation. Someone in that hospital needs a lesson in not being a complete douchenozzle. The only way it is acceptable for this information to be out there is if Lester or one of his reps are the ones who gave out the information.
Two questions in my mind. First, where was the source? From TM's article, I infer that it was NOT the team. It sounds like the Red Sox are doing all they can to respect Jon's privacy. Certainly something you should not be sharing with anyone, never mind taking it to the media. Couldn't agree more with smastroyin's point in the second paragraph above.
Second, though, does TM have an obligation to report the reason for the tests? I don't think so. There are some stories that you sit on, and this feels like one of them. In my book, responsible reporting here draws the line at "undergoing an extensive battery of tests at a Boston hospital." I think that would convey that it's potentially something serious without sharing personal business.
Of course, in sports, we're conditioned to want the story - and frankly speculate a bit. Exactly why is this pitcher going to Dr. James Andrews? What is the prognosis? How long will that players leg injury take to heal? When can he get back on the field? And the media does a good job of getting those stories. To Seth's point above, if the Herald reported a trip to Dr. Andrews and the Globe did not, we'd wonder about the relationship between the Globe, the Times, and the Sox.
It seems it might be a little different when it's something that's not baseball-related. And it's definitely different when you're talking about tests to rule, admittedly big, things in or out. Once the test results come back one way, then I guess there's a story. Until then, I think speculating steps over the line.
Prayers are with Jon and his family. We all hope he gets the all-clear and they all can look back on this as a scary period from a health perspective - which turned out perfectly fine.
