Prevalence and Epidemiology Interpretation
Risk Factors and Demographics
- Lymphedema can develop immediately after surgery or radiation, or even years later
- The incidence of lymphedema increases with age, particularly in patients over 50 years old
- Chronic untreated lymphedema increases the risk of cellulitis and other infections by 15 times
