It means the cancer doesn't have any of the receptors commonly found in other breast cancers. Basically, your cancer isn't being fed by hormones. That's a simplistic explanation. Sometimes after surgery, folk are told there is a receptor, so the diagnosis is changed. Not always, but sometimes.
My friend had grade 3 triple negative breast cancer last year she’s doing amazing now after chemo lunpectomy and radiotherapy she’s now back working full time
I also had breast cancer last year but not triple negative mine was her2 negative fed by hormone I now take a blocker tablet every day to hopefully prevent reoccurrence x
