I have recently been diagnosed with DCIS. I was sent for a breast check up on a lump as I was about to start HRT. This was benign, a collapsed cyst , but at the same time the physician suggested I have a mammogram to give them a base line in case I had any further issues. I received a call 2 days later to say I needed a core biopsy on my left breast. I have had that as I had a 6cm line of microcalcifications and have now been told I have DCIS in my left breast and need an operation. They think it’s low grade but how do they no for certain. I am so worried. I am normally a very level headed person but this has knocked me for six! I know I should feel lucky, as if I hadn’t had the mammogram I wouldn’t have known and they wouldn’t have caught it early, but I don’t. I am struggling to hold it together, my kids are sitting exams so have not said anything. I’m sorry as I know so many others are suffering with so much more but I just feel so alone.
