Diagnosis of Cancer of the bone

By feeling the warm, painful swelling in the bone, your GP can sometimes make an initial diagnosis of primary bone cancer, and you will be referred to a consultant for further tests.

Depending on the type of bone cancer, an X-ray of the affected area will show unusual bone. This may be a hole or holes in the bone, edges that are ragged rather than smooth, or a lump growing out from the bone. Sometimes a small amount of radioactive material is injected into your veins. This is absorbed more by abnormal bone than normal bone, so that when an X-ray is done, the abnormal areas show up more clearly. This type of bone scan is helpful for finding out if the cancer has spread to other bones.

A computerised tomography (CT) scan or magnetic resonance imaging (MRI) scan can be used to get a more detailed picture of the tumour, and to see if the cancer has spread to other organs.

A tiny sample of the tumour tissue (a biopsy) can be done using a needle. The cells can be examined under a microscope to check that the tumour is cancerous, and if so, what type of cancer is involved. If a needle biopsy does not give accurate results or is not possible in a particular part of the body, an open biopsy may be performed. This involves a minor operation to remove a small piece of bone.
