What is sarcoma?
A sarcoma is a bumpy tumor that occurs in the connective tissues (nerves, muscles and bones) anywhere in the body.
Sarcomas are rare, especially in young children. In kids between 10 and 20, sarcomas make up about 20-25% of childhood cancer diagnoses.
Sarcomas can start off being tiny lumps that you can’t feel. They can spread through the body, or metastasize, before they grow big enough to be seen.
