That's a very good question. I am not exactly sure how they're all appointed, but some of them are appointed through The College of Family Physicians. There were other bodies as well, I think, that recommended individuals.
What I've noticed, though, is that there tends to be over time—how can I put it?—a concentration of people who are like-minded. The like-mindedness tends to be an attitude that less is more and that somehow, when a woman finds a cancer, treatment alone is adequate, even if the cancer is found at a relatively advanced point.
There's a mindset that has accumulated and has been concentrated within the membership of the task force that tends to be like-minded on the subject and demonstrates a fairly clear bias against screening.
