Multiple Myeloma Cancer 

Multiple myeloma, also known as myeloma, is a type of bone marrow cancer. Bone marrow is the spongy tissue at the centre of some bones that produces the body's blood cells.

It's called multiple myeloma as the cancer often affects several areas of the body, such as the spine, skull, pelvis and ribs.

 

Symptoms of multiple myeloma
 

In the early stages, myeloma may not cause any symptoms. It's often only suspected or diagnosed after a routine blood or urine test. 

Eventually, myeloma causes a wide range of problems, including:

  • a persistent bone pain, usually in the back, ribs or hips

  • tiredness, weakness and shortness of breath – caused by anaemia

  • high levels of calcium in the blood (hypercalcaemia) – which may cause symptoms including extreme thirst, stomach pain, needing to pee frequently, constipation or confusion

  • weight loss

  • blurred vision, dizziness or headaches – caused by thickened blood (hyperviscosity)

  • repeated infections

  • bruising and unusual bleeding – such as frequent nosebleeds, bleeding gums and heavy periods

  • weak bones that break (fracture) easily – if this affects the spine, it might cause symptoms such as pins and needles, numbness and weakness in the legs and feet, and problems controlling your bladder and bowels, which requires emergency investigation

  • kidney problems

 

Myeloma doesn't usually cause a lump or tumour. Instead, it damages the bones and affects the production of healthy blood cells.

 

 

When to see a GP
 

See a GP if you have any of the symptoms of multiple myeloma. While they're unlikely to be caused by cancer, it's best to get a proper diagnosis.

Your GP will examine you to check for bone tenderness, bleeding, signs of infection and any other symptoms that suggest you might have myeloma. They may also arrange blood and urine tests.  If myeloma is suspected, you'll be referred to a consultant haematologist (a specialist in blood conditions) for further tests and treatment.

Causes of multiple myeloma
 

It's not known exactly what causes multiple myeloma. However, there is a close link between multiple myeloma and a condition called monoclonal gammopathy of unknown significance (MGUS).

MGUS is where there is an excess of protein molecules, called immunoglobulins, in your blood. This doesn't cause any symptoms and doesn't need treatment.

Every year, around 1 in every 100 people with MGUS go on to develop multiple myeloma.  There is no known way to delay or prevent this, so people with MGUS will have regular tests to check for cancer.

Multiple myeloma is also more common in:

  • men

  • adults over 60 – most cases are diagnosed at around the age of 70, and cases affecting people under the age of 40 are rare

  • black people – multiple myeloma is about twice as common in black populations than white and Asian populations

  • people with a family history of MGUS or multiple myeloma

 
Treatment for multiple myeloma
 

Treatment can often help to control the condition for several years, but most cases of multiple myeloma can't be cured. Research is ongoing to try to find new treatments.

Treatment for multiple myeloma usually includes:

  • anti-myeloma medicines to destroy the myeloma cells or control the cancer when it comes back (relapses)

  • medicines and procedures to prevent and treat problems caused by myeloma – such as bone pain, fractures and anaemia
