Tumour Information

Tumour growth or behavior will vary according to the type of tumour and depending on whether the tumour is non-cancerous (benign) or cancerous (malignant).

Most bone tumours are benign. They tend to grow slowly and don't usually tend to reoccur once removed from surgery. Benign tumours tend to stay non-cancerous except in rare cases. 

The most common benign types of tumour include:

  • Non-ossifying fibromaunicameral (simple) bone cyst
  • Osteochondroma
  • Giant cell tumour
  • Enchondroma
  • Fibrous dysplasia


Malignant tumours are cancerous and vary in size and shape. They grow in an uncontrolled and abnormal ways, interfere with bodily functions and can be life-threatening if not treated.

A malignant tumour which begins in the bone (primary bone cancer) is different from a tumour that begins somewhere else in the body and spreads to bone (secondary bone cancer).


The four most common types of primary bone cancer occurring in the hip are:

  • Multiple Myeloma: Multiple myeloma is the most common primary bone cancer. It is a malignant tumor of bone marrow
  • Osteosarcoma: Osteosarcoma is the second most common bone cancer and is commonly found in teenagers
  • Chondrosarcoma: Chondrosarcoma occurs most commonly in middle aged to elderly patients



Most patients with a bone tumor will experience pain in the area where the tumour occurs. The pain is generally described as dull and achy and may get worse with activity but this is not always the case. The pain often keeps the patient awake at night. 

Tumours are not caused by trauma, however, in some cases an injury can cause the tumour to start hurting. Injury can also cause a bone that is already weakened by tumour to break or fracture.

In some cases patients will not experience any symptoms of pain but instead notice a mass or lump.

Depending on the type of tumour they can be treated either surgically or non-surgically.
