- stareatgoats 3y agomany thanks - that's an interesting correlation! and the first I've heard of it. If there is a causal relationship here then that would surely account for a certain percentage of the change in cancer rate under discussion here, as women (in developed countries) tend to get their children ever later in life, and fewer of them.
