The causes of multiple myeloma are unknown but there are several factors that may increase your risk. They include age (most people are 50 or older), race (twice as many people people are African-American), being a man, being overweight, and having others in the family with multiple myeloma.
The only risk factor I have is being overweight. However I have an aunt who has a different blood cancer called Walden strums. So, we are beginning to think it could be genetic.
