Is it possible for skin cancer that is located on the breast to cause micro-calcs within the breast? I have had micro-calcs for years. They have increased in number, and changed pattern slightly. I have had MRI's, mamo's, and ultrasounds that came back showing solid nodules and simple cysts, as well as dialated ducts. I have had fibrocystic breast disease most of my life. I have had a FNB, wedge biopsy of the aereola, and biopsy of breast discharge, all of which came back ok. That is pretty much my history. I was just curious as to whether skin cancer could cause the underlying calcs, as I just a had a biopsy and am awaiting the results oin Tuesday.
