What is it?
Sarcomas are rare and affect the supporting tissues of the body such as bone and soft tissue (i.e. muscle or cartilage)
Ewings sarcoma can affect the long bones (like osteosarcoma), but also in the ribs, pelvis and spine. It can also occur in soft tissues, but this is rarer than in the bone. Primitive neuroectodermal tumour (PNET) is a type of Ewings Sarcoma that can occur in either the bone or soft tissue.
Exact causes of primary bone cancer are not entirely clear but the rapid growth of bones could be a factor, hence more commonly diagnosed in teenagers.
