Symptoms

The most common symptom of bone tumors is pain, but many patients will not experience any symptoms, except for a painless mass. Bone cancer is also very rare. For other uses, see Pain (disambiguation). ...


Classification

Bone Tumors can be divided into primary and secondary tumors. Secondary tumors can be further subdivided into:

  • Metastatic tumors
  • Tumors resulting from contiguous spread of adjacent soft tissue neoplasms
  • Tumors representing malignant transformation of the pre-existing benign lesions.

Neoplasia (literally: new growth) is abnormal, disorganized growth in a tissue or organ, usually forming a distinct mass. ...

Primary tumors

Primary bone tumors are rare (less than 1% of all malignant tumors) and are most common in young men. The four most common types of primary bone tumors are:

Bone cancer was once prevalent among individuals who painted radium on watch faces (to produce glow-in-the-dark dials), a practice that was abandoned in the middle of the 20th century.
Musculo-Skeletal Tumor Orthopaedic Practice (MUSTOP) (2469 words)
Tumors arising from small tubular bones such as the ulna, metatarsal, or metacarpal are usually centrally located and produce symmetric expansion of the bone.
Histologically, the tumor consists of a cartilaginous tumor of low-grade malignancy and a noncartilaginous high-grade malignant component.
In the bone, the lesion is lytic and stippled with calcifications, cortical destruction, and soft tissue extension.
