Why do Black women have the highest death rate for most cancers? New study aims to find out.

NEW YORK - The American Cancer Society is trying to find out why Black women have the highest death rate for most cancers.  

For example, they are twice as likely as White women to get stomach cancer, and 2.3 times more likely to die from it. Scientists aren't sure why. 

That's why they want to follow at least 100,000 Black women for 30 years as part of a massive study, called Voices of Black Women.
