(WZZM) - Daughters born to younger father's have a 35% increase chance of getting in breast cancer.
That's according to a study out of California of nearly 133,000 women.
It found that daughters born to father's under the age of 20 were most at risk. The study was presented at the American Association of Cancer Research.
Because breast cancer is a hormone-related cancer, City of Hope researchers wanted to look at a father's age at the time of conception to see how it affected the health of their children.
