What were the symptoms you originally experienced making you seek medical advice?

I was diagnosed in October 2016 after having pain in my armpit close to the wire in my bra. I thought it was the bra but after several new ones and no relief I called my obgyn he sent me for a mammogram. After my scan I was sent to have an ultrasound. Everyone I spoke to said breast cancer typically does not hurt at all. I’m not sure why mine did and no one could explain why but I am so grateful I did have pain other wise at 42 I would have never assumed it was cancer
