I was diagnosed with Idiopathic Granulomatous
Mastitis just a month ago. I had a normal mammogram back in Sept.2010, in early April my left breast was sore (but I didn't think much of it because I exercise), then one day my left nipple was inverted (which is abnormal for me), and that's when I felt a hard mass. I had a biopsy with ultrasound, later biopsy to get samples, then an excisional biospy 3 days ago. I'm in no pain, feel great which is so weird about all this.
