"My grandmother died of multiple myeloma and now my dad has been diagnosed with this disease. Is myeloma hereditary?

There is only a weak family tendency to develop myeloma. Approximately 3-5% of patients with myeloma give a history of myeloma or a related condition within the extended family. Thus far, no specific gene has been linked to this myeloma tendency. When family members get their annual check-ups, make sure that the physicians know about your family medical history. If standard laboratory blood work indicates an increase in protein, the doctor will have a note in the medical chart so that any protein increase is properly evaluated."
