Shocking Medical Mistakes

Molly says she went in for two mammograms, a breast ultrasound and an MRI, but doctors couldn't find a tumor. "I just remember being so scared and so confused about this because I had this cancer in me, and nobody could find it," she says.

Doctors diagnosed Molly with a rare form of breast cancer in which there are cancerous cells but no tumor. They recommended a mastectomy.

Molly had her right breast and 24 lymph nodes removed and then returned home to wait for more news. "I was at home waiting for the call. … How many lymph nodes have been affected? Where is it?" she says.

Eight days after the mastectomy, Molly got an urgent call from her surgeon asking her to come in. "At that point, I was thinking to myself, 'Okay, it's not going to be good,'" she says.
