Andrea Ivory is a woman on a mission. Four years ago she wanted to find her purpose in life. Little did she know it would be wrapped-up in the life-changing diagnosis of cancer. She turned what some would view as a death sentence into an opportunity to save lives. In Miami, Florida, Ivory goes door-to-door three Saturdays each month, five months a year, to get uninsured women to sign up for free mammograms. ESSENCE.com talked with the recent CNN Heroes nominee about what she thinks about the new mammogram guidelines, how her organization helps women who have positive screenings when getting tested, and why it is so important for her to travel to low-income communities.
