Myeloma, also known as multiple myeloma, has a certain heredity, but the specific influence of hereditary factors on the incidence of this disease is still unclear, and this disease may also be related to viral infections, physicochemical factors, chronic inflammatory stimulation. 1. Genetic factors: studies show that the incidence of multiple myeloma in certain races and families is significantly higher than that in other populations, so this disease may have a certain relationship with genetic factors. 2. Viral infection: human herpes virus type 8 and EBV may lead to the development of multiple myeloma. 3. Physical and chemical factors: the incidence rate of multiple myeloma is significantly higher than that of other populations among those who receive radiation, and the higher the dose of radiation received, the higher the incidence rate, suggesting that this product is related to ionizing radiation. There are also long-term exposure to pesticides, asbestos, arsenic, petrochemical products and so on can also induce multiple myeloma. 4. Chronic inflammation stimulation: those who suffer from chronic inflammation such as cholecystitis, pyoderma, chronic osteomyelitis, etc. are more likely to develop multiple myeloma. Patients with multiple myeloma should actively cooperate with doctors for treatment so as to avoid delaying the condition.
