A wealthy California enclave blighted by a cluster of extremely rare childhood cancers is now grappling with a second uncommon diagnosis. Jessica Keetch, from Orange County, revealed her daughter Haven, 18, lost her leg after battling synovial sarcoma, an aggressive soft tissue cancer that often appears as a lump on the leg. The disease is extremely rare in the United States, impacting less than 1,000 people across the country every year.
