There are certain things that can increase the chance of developing myeloma. These are called risk factors. Having a risk factor does not mean you will get cancer. And not having risk factors does not mean you will not develop it.
In the UK, around 5,800 people are diagnosed with myeloma each year. Doctors do not know what causes myeloma, but having MGUS (monoclonal gammopathy of unknown significance) increases the risk of developing it. MGUS is a non-cancerous condition where the body makes an abnormal protein, called a paraprotein.
Almost everyone with myeloma has had MGUS first, but it may not be detected. But only a small number of people who have MGUS develop myeloma.
Like other cancers, myeloma is not infectious and cannot be passed on to other people.
People who have a close family member (such as a parent, brother or sister) with myeloma may have a very small increase in their risk of developing it. If you are worried about this, your doctor can explain what the risk might be.
Some health conditions can weaken the immune system, or cause the immune system to attack healthy cells in the body by mistake (autoimmune disease). These types of conditions may slightly increase the risk of developing myeloma.

The language we use
We want everyone affected by cancer to feel our information is written for them.
We want our information to be as clear as possible. To do this, we try to:
- use plain English
- explain medical words
- use short sentences
- use illustrations to explain text
- structure the information clearly
- make sure important points are clear.
We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
