Actually, it is true. There was an in depth study done of Catholic nuns that showed the correlation.
However, I agree with you that this is not reason enough to reproduce. I know many people who cannot or chose not to have children.
Does it up their risk of getting breast cancer? Yes.
But then smoking ups one's chances of getting lung cancer and people do it all the time.
The abortion/breast cancer link has always brought to mind one question for me: What about women who've had miscarriages? It's pretty common. Does that up their chances of getting breast cancer as well?
Here's a link to the nun/cancer link:

True or not,(I don’t trust so-called “studies”, having kids should be up to the individuals or married couples. It is not mandatory or even necessary for loving, committed and healthy marriages.
Many people cannot have kids, many people should not have kids. That does make them any less valuable.
But, BTOS, I still don’t believe a word of this without hard physical proof. And no, so-called “studies” or testimonies do not count.
