Lymphedema

If you have swelling that may be due to lymphedema, your healthcare provider may do several tests to determine if lymphedema is causing the swelling. Those tests may include:

• Doppler ultrasound: This test looks at blood flow by bouncing high-frequency sound waves (ultrasound) off red blood cells. It can help find obstructions and rule out other possible causes of swelling, like blood clots.
• Magnetic resonance imaging (MRI): This test uses a magnet, radio waves and a computer to make a series of detailed 3D (three-dimensional) pictures inside of your body. Healthcare providers may use this test to see if something, such as a tumor, is putting pressure on your lymphatic system.
• Computed tomography (CT) scan:This test uses X-rays to show detailed, cross-sectional images of your body’s structures. Like an MRI, healthcare providers may use this test to check for signs something is putting pressure on your lymphatic system.

Are there stages of lymphedema?

Yes, healthcare providers use the following staging system:

• Stage 0:The affected area may feel swollen, tight and heavy but without outside signs of swelling.
• Stage I: There may be occasional swelling that goes away when you elevate the affected area.
• Stage II: The affected area is almost always swollen and your skin in the area may feel firmer than the surrounding area.
• Stage III: The affected area has significant swelling with changes in your skin such as changes in its color and texture.
