When beginning chemotherapy earlier this year, Olympic gold medalist Shannon Miller says that her biggest fear wasn't the cancer or the aggressive treatment, but how her son Rocco would react to her appearance.
"For me, the toughest part was facing my son, Rocco," Miller, 34 tells People. "He was 15 months old at the time that I was going through my treatment. He has lots of hair. And I wasn't sure if he was going to be scared of Mommy ... being bald."
