Causes and risk factors of myeloma
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
