Bone cancer is a type of malignant tumor that arises from the uncontrolled proliferation of cells forming bone tissue, leading to the destruction of bone structure. Tumors that originate in the bone itself are called primary bone cancer, while cancers that start in another part of the body and spread to the bones are known as metastatic (secondary) bone cancer. Osteosarcoma is the most common type of primary bone cancer seen in children and young adults. While this type of cancer is typically found in the bones of the legs and arms, it can less commonly occur in other bones such as the hip (pelvis), shoulder, or jaw.

Bone density is fundamental to bone health. Bone density, which depends on the amount of calcium minerals in the bones, generally reaches its highest level between the ages of 20 and 30. After this age range, taking specific measures to maintain optimal bone density is of great importance.

Among the primary causes of bone problems in young people are sports injuries, inadequate nutrition, and lack of physical activity. In older age, the prevalence of systemic diseases increases. These conditions can elevate the risk of bone tumor development and lead to bone pain. Since bone tumors can often progress without noticeable symptoms, it is crucial to consult a specialist immediately upon noticing any persistent bone pain.
