Why to be wary of even seemingly innocuous screening tests


A very telling study in the New England Journal of Medicine has concluded that people who are diagnosed with cancer have a markedly increased risk of suicide and cardiovascular death immediately after being given the diagnosis, a risk that stays up for several weeks.

Now, this study was done in Scandinavia so perhaps there’s something unique to the people up there – or with their doctors in how they communicate the diagnosis – that accounts for this rather worrisome result, but I doubt it.

I think the diagnosis of cancer is so scary that it can affect certain people (perhaps most of us) in a very adverse way, often more adversely than we may have thought when we weren’t as concerned that we might actually have cancer.

For me, the lesson from this is simply that even when people insist to you that there doesn’t seem to be a good reason against getting a particular screening test - PSA for prostate cancer, mammogram for breast cancer, whole body scans, etc etc – it always pays to ask yourself how you’d handle a result that indicated that – against the odds and certainly beyond your expectations - you had cancer.
