Hi. I have had a few issues with my breasts. First I noticed an indent in my right breast in December so was sent to the breast clinic. I had a mammogram on both breasts. Dr said not concerned but wanted ultrasound as saw some asymmetrical glands. They ultrasounded right breast. 
not long after I got a rash on my left nipple and a lump like spot. Gp said fungal as I was still breastfeeding my toddler. Gave me cream and rash went but I still had the spot like lump that's dermatologist and GP said was normal. 

4 weeks ago I noticed a lump in my left breast I went to a gp I didn't know and she just looked at breast and said no probelm( no exam) I went back a week later to my normal go and she said there was a lump and wasn't there in December when she examined me. 
i was then sent to breast clinic. The consultant sent me for ultrasound and I had a two needle aspirations and four core biopsies  of the lump. 
The radiologist said that it didn't look concerning on the image and thought it looked like a lipoma. The needle aspiration results come back after ten minutes as c2 which suggests it's benign. I'm still waiting on the biopsy results. Currently they have a back log so it's 3 week wait ( private hospital) I have appointment on the 11th April. 
im really worried even though consultant believes it to be benign. Why did the lump not show on the mamagram in December? I've been having aching in this breast since September last year. It's not constant so thought it hormones. 
Today my armpit on my left aches and I'm not sure if I feel a lump in the middle. 
I don't know what to do anymore. They believe the lump to be benign but I don't know why it's grown so fast and why my arpit is now sore. 
many breast is black and blue just now and still swollen where they took biopsies. 
anyone have experienced this and any advice. My auntie had breast cancer and said you don't really experience pain. My friend passed away in December from secondary breast cancer. 
I'm 41 and have three children. I stopped nursing in December.
