 Sarcoma. Odds are you've never heard that word before. But for the 40 people diagnosed with sarcoma every day, it is a life-changing word. Life-changing and devastating because sarcoma is cancer. Sarcoma is a cancer of bone and soft tissue more prevalent in children than in adults. More than 6,000 people lose their lives to sarcoma each year. Treatment options for sarcoma are limited and new therapies are desperately needed.
