It would be best if you formally move the amendment. It appears that the Conservatives have already made up their minds about it, or at least one of them has.
I'm going to take that to mean the motion is being amended. The amendment is to change the word “reversed” to “reconsidered”, and after that, the wording would be “that consideration be given to extending breast cancer screening” and so on. I think that's the essence of what you have suggested.
