Hi, I have pain on my Left breast, itchy nipple and black heads on my left armpit. Ill be turning 59 y.o this coming April. My last mammogram said I have dense breast. The pain increases when I have menstruation, a week before menstruation or when I had too much coffee intake. Do I need to see a doctor? My last left breast ultrasound 5 years ago, they find a cyst that the size is still the same 6 months later after a repeat ultrasound? Please help me what to do.
