Sarcomas are cancerous tumors of connective tissue, such as fat, blood vessels, nerves, bones, muscles, deep skin tissues, and cartilage. Sarcomas can develop in children and adults. For children under 20 approx. 15% of cancers are sarcomas. Dr. Sujana Movva, Oncologist at Fox Chase Cancer Center, specializes in bone and soft tissue sarcomas. Her current research includes tumor molecular profiling, key to targeted treatment of this rare cancer and others.
