Recently diagnosed

Hi, i was recently diagnosed with Breast cancer, I'm already living eith cancer after being diagnosed with a rare cancer called Gist (Gastrointestinal Stromal Tumours) last May, to then be told i had breast cancer as well was a bit of a shock as you can imagine. I hadn't found a lump i just a have a pain in my left breast, the tumour is under my nipple and is nothing to do with the pain. I've been told i will lose my nipple but can have it tattoed back on after a while and wondered if anyone else had had this done and what it looked like afterwards.
