In June, 2009, my mammogram showed a lump in my right breast. A biopsy in July ruled it as fibroadenoma. In November, I found a lump in my left breast and left armpit with left nipple discharge and itching. Decembers mammogram showed that lump in my armpit was an enlarged lymphnode (which is still enlarged). In February, 2010, the itching was so severe that I had to go back to my specialist and they did a bunch biopsy on my left areola. It looked like Paget's Disease and/or Inflammatory Breast Cancer. Results said it was dermatitis, which even started on the right areola. NP also found a small lump around the 3 o'clock area on the left breast. Then, in April, I found another lump around 5:30 on the left breast. Went to regular doctor and he sent me back to specialist. NP, my doctor, and I all agree that it's probably just another fibroadenoma. Again, the NP felt the lump at the 3 o'clock area and said we need to be concerned about it. She had me go for another mammogram. The mammogram showed neither lump, even though all three of us felt both lumps. It did, however, see the tail end of the enlarged lymphnode in my left armpit. I am due to go back in June to my regular doctor, my yearly mammogram, and my 3 month check up with the Breast clinic.
I am 41 years old and have large and dense breast. My 1/2 niece on my fathers side had breast cancer in her left breast when we were 36 years old. We are only a week apart in age. She had to have her left breast removed. Can all of these different non-cancerous issues turn into cancer? Should I be concerned over all these different breast issues? Should I be worried or concerned about the two lumps felt, but not seen on the mammogram?
