Hi. I’m slightly panicking. I have found a lump in my left breast. I check every month so this is new. It’s smooth and hard but behind my nipple and the nurse said she couldn’t move it. It seems to have appeared since mirena was removed and I started utrogestran (on HRT). At the breast clinic tomorrow late afternoon. Absolutely petrified it’s sinister because I can’t move it. Seems achy sometimes especially in the evenings. Anybody else experienced this? It’s that it’s not movable that’s worrying me and now I’m second guessing that I’ve not been checking correctly previously!
