Don't know. My big lump on bottom of breast (under the overhang if you know what I mean) showed up on MRI but not on mammo or ultra sound. Think this is more common for lobular because that is what they thought it was. Also interesting how sizes of lumps seem to vary on different scans.
Can anyone tell me why my offending TNBC showed up on my mammogram but not my MRI scan ? Just awaiting surgery and is something that has popped into my mind.mis it because it is inner quadrant and so closer to chest wall so can't be seen as well? Just occurred to me, anyone know the answer
