This is a phenomenon that Tara Parker Pope takes on here. Overtesting and overtreating is a huge problem, and it's one that's finally getting some attention. Granted, some of it is negative attention from the oh-my-god-death-panels crowd, but it's a serious question. Multiple screening tests have fallen under fire for the possibility that they cause more harm than good; intervals have been lengthened, the ages at which screening begins have gone up, or the test is no longer recommended as a routine screening. These recommendations are politically contentious, to say the least.
I've had a couple of run-ins with overtesting in the last few years that have left me a skeptic. I found myself guilted into a mammogram at the age of 35 because my mother had breast cancer. After menopause. This means that there is no statistical increase in my risk, according to the doctor I saw. He wrote for it, though, and told me that it was the safest way to go. The nurse was horrified that I wasn't going to schedule it. So I went against my gut and did it anyway, because I can be a wimp like that. My insurance, of course, did not cover it and they shouldn't have. Completely unnecessary.
I'm a lot less wimpy about that sort of thing now.
I've had two clear episodes of a neurological problem that looks an awful lot like MS. The thing is, there is no evidence of MS on MRI, or at least there wasn't the last time I had one, which was about a year ago. Efforts to diagnose the problem involved 3 specialists, 7 MRIs, and countless panic attacks. SEVEN MRIs, in less than 3 years.Multiple rounds of bloodwork, too, some of which again the insurance rightly refused to pay for, given that they were duplicates of labs that would not have changed I went along with this because I trusted my neurologist. But when I went up to see a neurologist at Tufts, he asked me why all of this had been done. And I didn't have a good answer for him. He gave me permission to stop seeing doctors, and apart from the 6 month follow-ups with my regular neurologist, I have. And at the last check? I turned down yet another MRI, since my symptoms haven't changed significantly since the last one.
The question of where to stop is a thorny one, but very, very important, and I'm glad that we're starting to look at it. The skepticism is overdue.
