Core Tip

Core Tip: With age, the risk of monoclonal gammopathy of undetermined significance increases, ranging from 2% to 3% over the age of 50 and approximately 5% over the age of 70. In addition, obesity increases the risk relatively. The cause is unclear. Genetic factors, environmental factors, radiation and chemicals (such as pesticides, herbicides) may have a certain impact on the occurrence of this disease. The risk of infection is higher than normal, the risk of osteoporosis and fractures is increased, and the risk of thrombosis is increased. Tumors with monoclonal gammopathy of undetermined significance should be given more attention.
