Although very slightly. For example, we can say that each year of breastfeeding reduces the risk by about 7%, and each childbirth by about 9% - all these "discounts' ' are summed up.

However, the relative risk is not the absolute one.

In terms of absolute risk, this "discount" does not look so much fun. For example, according to 2015 data, the risk reduction will be about 2.3%.

In addition, these numbers will no longer be relevant for those who have oncogenic mutations.
