blockage in the veins

Answer 1

Lymphedema is primarily caused by a blockage in the lymphatic vessels. This blockage can result from various factors, including surgery, radiation treatment for cancer, infections, trauma, or congenital issues. While issues with veins and high blood pressure can affect fluid balance in the body, they are not direct causes of lymphedema. Lack of valves in the lymphatic system is not typically cited as a cause of lymphedema, as the lymphatic system is designed to manage fluid balance with its own mechanisms. Therefore, the most accurate response from your options is:

- **blockage in the lymphatic vessels**
