Causes and risk factors of myeloma
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.
A weak immune system increases the risk of developing myeloma. Some conditions, such as HIV, reduce immunity. People taking medicines to weaken (suppress) their immune system after an organ transplant are also at a higher risk.
Autoimmune diseases cause the body’s immune system to attack healthy cells in the body. These autoimmune disorders slightly increase the risk of myeloma:
- Pernicious anaemia
- Haemolytic anaemia
