Past few months, I notice an occasionally painful hard lump
at 5 o clock location in my right breast
. Mammogram, MRI, and Ultrasound rule out malignance and fat necrosis. What could be the cause for this hardness? My Breast Care Surgeon has no clue on why would this one will develop after ~ 10 years but plans to do a biopsy to rule out malignancy for sure.
Any suggestion as to what this lump could be due and should I remove it (even if it is benign?
