For those of you who take comfort in the fact--and I hear this a lot--that "there is no breast cancer in my family:

We don't know why most women get breast cancer. Only one out of 10 or one out of 20 has inherited a germline mutation from her parents, so that means that 19 out of 20 women who get breast cancer get it because of something that happened after they were born.
