Blizzard sent out the following

 

As a brilliant scientist and the guardian angel of Overwatch, Dr. Angela Ziegler—codename Mercy—has dedicated her life to helping and healing others. From May 8th through May 21st, players can help Blizzard Entertainment and the Breast Cancer Research Foundation work toward a cure for breast cancer by purchasing the new PINK MERCY skin available now for a limited time on PC, PlayStation 4, and Xbox One.

But this isn’t the only way for players to show their support! We’ve also created a limited-edition Pink Mercy charity shirt, unleashed a unique collection of Pink Mercy sprays and player icons you can get as Twitch Drops, and rallied an epic team of Overwatch content creators to stream for the cause. Please see below for all the ways players can support:

This is a brilliant move to make and will help raise a lot of money to help the search for a cure for this disease.
