Five years ago, Offset lost his grandmother to bladder cancer. Now, the rapper, who's a member of the platinum-selling rap trio, Migos, is doing his part to combat the disease by launching a $500,000 cancer fundraising campaign in her memory.

Aligning himself with the American Cancer Society, Offset is raising funds to support cancer prevention and "access to care in underserved communities."

Before her death, Offset's grandmother Sallie Ann Smith acted as one of his most important mentors. "It was really tough losing my grandma to cancer and one of the hardest things I have dealt with in my life," the hit-making rapper wrote on the American Cancer Society's page for his campaign. "She motivated me to do my best and go for it; one of my biggest coaches.”

For her part, Offset's mother, Latabia Woodward, admires Offset's jump into the fight against cancer. “Losing a loved one to cancer is devastating, and we need to continue to help educate our communities about early detection and screening guidelines. I am incredibly proud of Offset’s desire to help save the lives of others, genuine heart, and talent as an artist," she wrote on American Cancer Society's page.

Offset is also incorporating a sweepstakes into his campaign. If you donate $10 or more, you will be entered for a chance to be flown to Los Angeles for a shopping trip with the Migos rapper. To donate to Offset's fundraiser, visit the American Cancer Society's donation page.
