I saw that and clicked on the link. The font made it unreadable. I have also read that it was a very good study, 25 years long, 900+ subjects. The fact that it was done in Canada is meaningless. The fact that Canada has socialized medicine is meaningless.
Ok, well, the report at the link points out that the study relied on poor-quality, secondhand machines and the technicians weren’t trained properly.
So, assuming the report is true, then this Canadian study just tells us what happens when poor-quality, secondhand machines and poorly-trained technicians are used.
Believe me, I’d like to believe the study. Then I’d feel much better about my decision not to have a mammo. :-( Yes, there are many cases in which the mammo doesn’t catch anything. I might’ve been one of those cases, if I had one earlier, but who knows...
