The question of inheritability was raised at the Myeloma UK Patient Information Day last weekend. Professor Graham Jackson, clinical advisor to Myeloma UK, said it’s like having 3 or 4 tickets in the lottery, as opposed to a single ticket. Having family members with the disease does increase your chances of developing it, but you are still very unlikely to do so.
In USA there has been a study going for the past few years testing family members over 40. This may shed light on the most effective way to catch myeloma early.
The fact that you are aware of potential symptoms of myeloma will help you seek testing should any occur. The crucial test (which doesn’t catch everyone, but does the majority) is electrophoresis testing that shows a spike of Monoclonal protein.
