Is Multiple Myeloma Hereditary?
Multiple myeloma is not considered hereditary, because the cause of multiple myeloma is not known. It is uncommon for myeloma to develop in more than one member of a family, as plasma cell changes are acquired, not inherited. This means that if you have myeloma, you probably do not need to worry about the disease developing in another family member. There is, however, a slightly increased risk of myeloma occurring in children or siblings of individuals who have the disease. This may be related to the genetic factors that are thought to be involved in the development of multiple myeloma.
