Is breast cancer a sex-linked trait or an autosomal trait


Is breast cancer a sex-linked trait or an autosomal trait?
I am trying to figure out if breast cancer is inherited and this is part of what I need to know.

Breast cancer isn't inherrited, but a higher risk of it is. If your relatives had cancer, you likely will as well.

In my family, our Oncologist all agreed that we inherited the gene. All of us, which is 7 of my sisters, some of my nieces, all had the testing at Dana Farber Cancer Hospital in Boston for the BRACA 1 & 11 gene. We all tested positive. That is so rare and though it may be rare, it shows that breast cancer can be inherited. My grandmother, (mom's mother) died of breast cancer. All of my mother's sisters got cancer, 5 if them, only 1 did not die. My mom was the only one who never got breast cancer or any kind of cancer. So I'm guessing we got the gene from our grandmother and my mother inherited her father's gene. What luck huh. Only one of the nieces tested negative. Her sister tested positive and she had breast cancer anyway, with a bi-lateral mastectomy, but she is the only one that tested negative. For her, I'm guessing she inherited her mom's gene, my sister-in-law who never got breast cancer. There is such controversy over family history. Is it inherited or not? The answers lies in the genes and unless one has the gene testing, they won't know. Blessings

Only 5-10% of all breast cancers are hereditary and they are not sex-linke
