FYI I won't be returning to this post this is just help if I can.
I have been breastfeeding for almost 2 years. I found a lump a year ago and my doctor said it was fluid filled.
After 3 visits they finally sent me for a scan. I ended up needing a biopsy as it was a solid lump. I KNEW it wasn't what the doctor said it was. It has ended up being benign but the point is I just listened and went along with the doctor.
Even if this post only helps ONE person. TRUST YOUR OWN JUDGEMENT. PUSH.
