I tried to use the abortion - breast cancer link to advance the pro-life position with someone at a party, and that person countered with "what about China, where they have widespread abortion and even forced abortion... why doesn't China have the highest breast cancer rates in the world?"

I was not able to answer that.

They have a very different diet there, later onset of fertility on average, and lower life expectancy in general, so it's apples and oranges.

I think life expectancy in China for women is around age 54 or so. In that case, many aren't living long enough to get cancer anyway.

The obvious answer is that there is in fact no link.
