Myeloma, also known as multiple myeloma, has a typical life expectancy of 4 to 5 years after treatment, with some patients surviving longer. Multiple myeloma is a common malignant disease of the blood system, and patients usually suffer from anemia, weakness, and general wasting. 1. The average life expectancy of multiple myeloma patients after radiotherapy is usually around 4~5 years, but it depends on the condition. Drugs include bortezomib, cyclophosphamide, lenalidomide and so on. 2. If the patients themselves are in good physical condition, have high immunity and the degree of disease is mild and the treatment effect is good, the patients’ life expectancy may also be around 10 years. On the contrary, if the patient has poor physical condition, low immunity and severe disease, the treatment effect may be reduced, and the patient’s life expectancy will be less than the average, usually around 2 years. Patients with multiple myeloma should maintain a good state of mind, pay attention to nutritional supplements, and exercise appropriately. Treatment should be carried out under the guidance of a physician.
