What is the typical life span of people with myeloma?

Variabe. In recent years there have been significant strides in the treatment of myeloma which have resulted in a significant prolongation of survival. There are now many long term survivors (5 yrs or more) although we don't believe the disease is truly curable at this point.
Variable. It depends on factors such as stage of disease, chromosome changes and other medical problems. Age may also impact survival as older patients may not be candidates for a stem cell transplant but the average is probably around 5-6 years. People surviving 10 or more years is not uncommon.
