Study Notes
Lymphedema vs Peripheral Edema
- Lymphedema is distinguished from peripheral edema by its chronic and irreversible nature, whereas peripheral edema is reversible and can be treated with diuretics and elevation
Fluid Circulation
- 90% of fluid returns to the circulation via the bloodstream, while the remaining 10% is drained by the lymphatic system
- The remaining 10% of fluid in the circulatory system is drained by the lymphatic system, which plays a crucial role in maintaining tissue pressure and preventing edema
Lymphatic System Function
- The lymphatic system primarily serves to drain protein, excess fluids, and waste products from the interstitial space
- 90-95% of fluid returns to the circulation via entry into venous capillaries
Breast Cancer-Related Lymphedema (BCRL)
- BCRL is characterized by chronic swelling of the arm, shoulder, or chest wall on the affected side following breast cancer treatment
- BCRL can occur as a result of surgery, radiation, or chemotherapy, damaging the lymphatic vessels and nodes, leading to impaired lymphatic drainage
Learn about the recent advances in the treatment of breast cancer-related lymphedema, which is a significant complication for many breast cancer survivors. Understand the challenges and potential solutions for managing this condition.
