As Dr. Gordon said, this has been done before. It can be done again. I think there are better ways to do these guidelines. As we've seen, the U.S. task force's model recommended screening women aged 40 to 49.
There are other guidelines. There are the National Comprehensive Cancer Network guideline and the provincial screening guidelines. Almost every other guideline you could throw a stick at recommends screening at 40. It's just the Canadian task force that is entrenched in this idea that women 40 to 49 shouldn't be screened, and I think that is a symptom of the more fundamental problems with the task force.
