Donna Pinto was 44 in January 2010 when she was diagnosed with ductal carcinoma insitu, or DCIS. It's also known as Stage 0 breast cancer. "I was numb and I was almost paralyzed and I really don't think I heard anything further other than that," Pinto says after hearing the news. DCIS refers to abnormal cells trapped in the milk ducts. She says she endured painful diagnostic tests and surgery. InsideEdition.com's Mara Montalbano (  / maramontalbano  ) has more. #InsideEdition
