If you needed another reason to prove Offset is the best member of the Migos, here it is. Offset has teamed up with the American Cancer Society to give back in a major way, launching a $500,000 fundraising campaign for cancer research.

The death of Offset’s grandmother due to cancer was all the inspiration the rapper needed to participate in raising money for the organization. “It was really tough losing my grandma to cancer and one of the hardest things I have dealt with in my life,” he remembers. “She motivated me to do my best and go for it; one of my biggest coaches.”

The American Cancer Society made the official announcement on social media.

“Rapper Offset, of the chart-topping hip-hop trio Migos, is raising $500,000 for our organization,” their Instagram post read. “He is honoring his grandmother by raising funds to help promote cancer prevention and access to care in underserved communities. In addition, money raised through this effort will also help fund an ACS Research Grant focused on bladder cancer research.”

Fans can donate to the cause by texting OFFSET to 41444. They will also be entered for a chance to go on a shopping spree with Offset in Los Angeles.
