What causes estrogen positive breast cancer?

I was reading about this because my aunt was diagnosed recently. From what I understood, normal breast cells have receptors for estrogen, but in this cancer, the cells have too many receptors and grow out of control when estrogen binds to them. It is mostly linked to genetics, age, and sometimes lifestyle factors.

Instead of spending hours reading confusing articles online, please consult an oncologist. Estrogen positive breast cancer is primarily caused when estrogen hormones fuel tumor growth, often due to genetic predisposition or hormonal imbalances. Get an official biopsy and IHC report analyzed by a professional.

My mother was diagnosed with ER-positive breast cancer back in 2021. The doctors told us her body was producing excess estrogen which was feeding the cells. She underwent hormone therapy after surgery, and touchwood, she is doing absolutely fine now.

Listen, don't let the internet scare you with worst-case scenarios. Estrogen-receptor positive is actually a very well-researched type of breast cancer, and the treatment targeting estrogen is highly effective. Just support whoever is going through this and stay strong, the medical field has advanced a lot.

We actually studied a bit about this in our biology class. It is basically when the tumor cells have receptors that lock onto estrogen to multiply. Don't stress too much about the term, doctors have really specific treatments designed just to block this hormone.
