What It Is

Tumors are lumps or masses of abnormal tissue that form when cells in a bone divide uncontrollably (AAOS, n.d.). A growing tumor, even a noncancerous one, can destroy healthy tissue and weaken the bone, making it more likely to break (fracture). Most bone tumors are noncancerous (benign), but some are cancerous (malignant). Benign tumors are not life-threatening and, in most cases, do not spread to other parts of the body. A malignant tumor can spread cancer cells to other parts of the body (metastasize) (AAOS, n.d.).

Cancer can also start somewhere else in the body, such as the breast, lung, prostate, kidney or thyroid, and spread to bone. This is called secondary bone cancer (or metastatic bone disease), and it is treated differently from cancer that starts in the bone (AAOS, n.d.; NHS, 2025b). Multiple myeloma, a cancer of the bone marrow, is the most common cancer that starts in bone, and is mostly seen in people aged 50 to 70 (AAOS, n.d.).

Bone Tumor Anatomy

To gain a better understanding of a bone tumor, it helps to understand bone anatomy. The skeleton is a living structure that supports the entire body. Bones are made of an outer shell of dense bone surrounding a honeycomb structure of softer bone.

Two sections make up the human skeleton (National Cancer Institute, n.d.)

  • Axial skeleton – The axial skeleton has 80 bones in total, including the skull, spine and chest.
  • Appendicular skeleton – This skeleton has 126 bones, including the limbs, hands and feet, and the shoulder and pelvic girdles that attach them.

How to Know if You Have a Bone Tumour?

Many benign bone tumors cause no symptoms at all and are found by chance on an X-ray taken for another reason; some people notice a painless lump (AAOS, n.d.). When a bone tumor does cause symptoms, the most common is pain in the area, usually a dull ache that can be present at rest and may be worse with activity. Pain at night or when you are resting is a concern and should be checked by a doctor (AAOS, n.d.). Bone tumors are not caused by injury, but an injury can make an existing tumor start to hurt (AAOS, n.d.).

See your family doctor or nurse practitioner if you have (NHS, 2025a)

  • pain or tenderness in a bone, particularly if it is worse at night
  • a lump or swelling, or weight loss you can't explain
  • pain in your bones or joints that is making it difficult to move around

Other symptoms can include feeling very tired, a high temperature (fever) and sweating (NHS, 2025a; AAOS, n.d.). You might not have a bone tumour, but it is important to get your symptoms checked, because finding bone cancer early can make it easier to treat (NHS, 2025a).
