DALLAS, TX -- The Catholic Medical Association (CMA) welcomes Senator Rick Santorum as this year's conference keynote speaker. The staunch pro-life leader will candidly share his family's personal story regarding his 7th and youngest child Bella's life-threatening condition. Now 10, Bella was born with Trisomy 18, a rare chromosomal abnormality. Only half of those born with it survive a week; fewer than 1 in 10 make it to their first birthday.
