You might think that screening for breast cancer by mammography is a slam-dunk. It was not the last time I wrote about it; and it is not now.
In a YouTube video sent to me recently, the head of the Nordic Cochrane Center makes an emphatic case against breast cancer screening. This is important, because Cochrane is among the leading sources of medical evidence assessment and synthesis in the world, and those who run their centers are highly qualified to judge such evidence. On the other hand, this particular expert is a rather inveterate contrarian, opposing much of what “Big Medicine” does. That doesn’t make him wrong, but it does highlight his penchant for staking out and defending extreme positions.
