I have a little example that might help. A few years ago I went to my surgeon—it was post-surgery—and I asked him for supplemental screening because I have dense breasts. He said, “No, it's not recommended. The task force says you don't need that.” I told him that there were no oncologists on the task force, and his jaw dropped. He didn't know that. He had been telling all of his patients they didn't need supplemental screening. He said at the next appointment that ever since, he'd been recommending ultrasounds for all of his patients with dense breasts.
Doctors don't have time to be conspiracy theorists about the task force giving them bad advice. They just have to assume they're getting good advice because the Government of Canada stands behind it. This is the official word of the experts, and I don't think a lot of doctors know there aren't any oncology experts on the task force.
