I found a lump above the top of my implant towards my armpit on the right side back in October. At times I will have a dull pain deep within the breast are around the same area of the lump. The size has not changed to my knowledge. It is the size if two grapes sitting side by side. I had blood work and a chest xray the end of January results came back fine, with the exception of having a vitamin D deficiency. I then had a mammogram as well as a ultrasound, again was told things are fine. They were not able to visual see the lump via ultrasound though, A few days after I had these test done my gp called to schedule a breast MRI. I do not have insurance now and am unable to pay for the MRI anytime soon. What could this lump be?
