Hi D.,
I found a hard area in my breast that I had my doctor take a look at at my six-month post-partum checkup. He thought it was just an enlarged blood vessel, but decided to send me in for an ultrasound anyway. I went to the Breast Center at Memorial Hospital in LB, and they decided to do a mammogram first. The radiologist reviewed the x-ray, said yes, there is a lump, and sent me to the ultrasound room. The doctor came in and did the ultrasound, and biopsied it while I was there. It turned out to be a cystic adenoma (non-cancerous tumor common in lactating women). I have continued to breastfeed and I have a follow-up mammogram in November.
Just be prepared to pump or nurse prior to going in for your mammogram, as having milk in there will make it more difficult to read the x-ray. Also, another FYI, after they did the biopsy they asked me not to nurse or pump for at least six hours that day to allow the breast time to heal and to stop bleeding. The milk I pumped was pink the first two days, and it took a few days of pumping and dumping before the blood was gone. Your daughter is old enough that she can have whole milk if you have to have a biopsy; you won't see any blood if your daughter is strictly nursing.
You can still nurse while having a mammogram, just try to have your breasts as empty as possible before you go in.
Good luck whatever you decide.
