In brief: Breast cancer risk
20 percent lower if the first birth was at age 20, 10 percent lower for first birth at age 25, and 5 percent higher if the first birth was at age 35 .
The risk for a nulliparous woman is similar to that of a woman with a first full term birth at age 30.

In brief: A little bit
The most important risk factors for breast cancer are being female and being older. Breast cancer is relatively common in women over 60 and very rare in women less than 30, for example.
The other important risk factor is having one or more immediate family members with bc. Not having children, or having them late in life increases your risk a little bit. Check out the gail model online.
