The life expectancy for someone with multiple myeloma depends on the stage of the disease when diagnosed, according to the American Cancer Society. Stage I patients have a median survival rate of 62 months. Stage II patients have a life expectancy of 44 months, and stage III is 29 months.
Median survival refers to the amount of time it took for half of the people in a specific study group to die from the disease. Researchers use median survival as an average, but generally, patients can expect to have a better chance than the average median survival rate, according to the American Cancer Society.
