Mine was in the inner lower quadrant on left side.. about 8 o’clock area if my breast was a clock. It was invasive lobular carcinoma. It was not a round hard lump. When I was doing self exam it felt long and mushy kind of like a cigar. I knew it was not supposed to feel like that. Next day, in 2013, went to breast clinic and from there did Mamo, ultrasound, biopsy where I was diagnosed.
