I have fibrocystic breasts and was told that I have a lump, that they should be symmetrical on both sides.I have a lump on my right breast, into my armpit, with an electric pulse that feels like it s shooting through the nipple on the same side (several times per day). I had a mammogram last year and they detected a mass, but said it was non-cancerous. This painful lump has been with me now for more than 4 months and it s getting worse, and it s getting bigger. I feel like having another mammogram seems redundant, since I just had one (late) last year. There are no other physical changes in appearance to my breasts. Your thoughts are very welcome!
