When cancer strikes and doctors are required to remove a body part to cure the illness, it's not uncommon for patients to feel as if they have a defect. When a woman has a mastectomy and loses one or both breasts, feeling whole again can be especially difficult, Dr. Oz says.

"At the end of the day, one of the first questions you ask if you have been cured of your breast cancer is, 'Now what do I do? How do I look normal again? How do I keep the sexuality that is part of our existence intact?'"
