I had mastitis approx 12 months ago, despite not breast feeding for 4 years. As part of that, I had a lump under the breast - imagine a mint humbug shoved under your boob. It was solely to do with the infection and was confirmed to be so after multiple scans and a biopsy.
I remember there being a "knot" in the boob after I had my biopsy.
Last night in bed i was itching myself and am sure i found a lump/knot. I asked DH to feel aswell and he says there's nothing there. I can feel it with my palm. Only just, but it's there. I am certain it's just the knot/scar tissue from the biopsy site. (The insertion was much further back from the biopsy site - they essentially inserted from the chest wall towards the nipple.)
Is it worth popping to the GP to be sure?
