You can get cancer in your bones
Osteosarcoma - cancer of the bone-forming cells
Osteosarcoma arises from the cells that normally make bones. Typical of osteosarcoma is that it produces immature bones (osteoid). It still forms the basic substance of the bone, but no lime. In this way, an osteosarcoma can also be easily distinguished from other bone tumors.
Osteosarcoma is the most common malignant bone tumor in children and adolescents. Every year around two to three in a million children and adolescents (around 40) develop it again, most frequently between the ages of 10 and 25.
Osteosarcomas mainly develop in the sections of the long tubular bones of the arms and legs near the joints. Doctors discover over 50 percent of all osteosarcomas in the knee joint.
Ewing sarcoma - cancer of the soft bone tissue
Ewing's sarcoma forms in the soft tissues of the bone: in the connective, fat and muscle tissue or in the tissue of the peripheral nerves. Ewing's sarcoma is the second most common malignant bone tumor in childhood and adolescence. In Germany about two out of a million children under 15 years of age (about 36) and 2.4 out of a million adolescents get it, preferably between 15 and 25 years.
In principle, Ewing's sarcoma can develop in any bone. It occurs particularly often in the pelvis, in the long tubular bones of the upper and lower legs (calf and shins), in the ribs or in the upper arm.
Chondrosarcoma - cancer of the cartilage
The chondrosarcoma has its origin in the cartilage of the bone. It makes up about ten to 20 percent of all malignant bone tumors. Most people with chondrosarcoma are between 40 and 60 years old. This bone cancer forms particularly often in the pelvis, trunk, shoulder girdle, in the upper area of the thigh and in the upper arm.
Bone cancer in children
Overall, bone cancer in children and adolescents is very rare, but it is more common than in adults. In adulthood, bone cancer only accounts for around one percent of all malignant tumor diseases. In the case of children, however, it is around five percent.
The osteosarcoma and Ewing's sarcoma are particularly difficult for children and adolescents. Some already have metastases in other organs when they are diagnosed with bone cancer. You have to undergo severe therapies from a young age and spend a lot of time in the hospital. Even in later years, they often suffer from the consequences of bone cancer and the treatments.
