“statistically it's true that those who have biopsies have a greater risk of developing breast cancer. The reason is because a certain percentage of women who have biopsies will end up with the discovery of a 'high risk' condition.  That's what increases the risk.  So it's not the simple fact that you've had the biopsy that increases the increase; it's the result of the biopsy that increases the risk. Let's say 100 women have biopsies and all start with a risk level of 4%, which is the starting risk level of someone with no other risk factors - basically it's our risk just for being women. The average risk level for that group of 100 women, prior to the biopsies, is 4%.  Of those 100 women, 20 are diagnosed with breast cancer.  Of the remaining 80 women, 10 are found to have a condition that increases risk, something like atypical ductal hyperplasia or LCIS. The lifetime breast cancer risk level of these 10 women jumps, let's say, from 4% to 20%.  Doing the math, this means that the average risk level of the group of 80 women (those not diagnosed with breast cancer) is now 6%. That's why all the websites talk about biopsies increase risk. Overall, on average, they do. But for those whose biopsies showed a totally benign, non-high risk condition (such as standard benign calcifications), the risk level remains 4%.
