I was doing self exam and felt a tiny little bump the size of a grain of Sand. I scheduled a screening mammogram but because I said I felt something they send me straight to a diagnostic mammogram. Radiologist said I was fine. Radiology technician told her she thought she saw something. She insisted I was ok and radiology tech told her to turn me over and then I heard radiologist says "oh" and kinda panic. Anyway was send for biopsy which proved I had extensive multi focal DCIS. The fun part. That little grain of Sand proved to be nothing !
