Lymphatic system

Diagnosis If you're at risk of lymphedema — for instance, if you've recently had cancer surgery involving your lymph nodes — your doctor may diagnose lymphedema based on your signs and symptoms. If the cause of your lymphedema isn't as obvious, your doctor may order imaging tests to get a look at your lymph system. Tests may include: • MRI scan. Using a magnetic field and radio waves, an MRI produces 3D, high-resolution images of the involved tissue. • CT scan. This X-ray technique produces detailed, cross-sectional images of the body's structures. CT scans can reveal blockages in the lymphatic system. • Ultrasound. This test uses sound waves to produce images of internal structures. It can help find obstructions within the lymphatic system and vascular system. • Lymphoscintigraphy. During this test, the person is injected with a radioactive dye and then scanned by a machine. The resulting images show the dye moving through the lymph vessels, highlighting blockages. Treatment There's no cure for lymphedema. Treatment focuses on reducing the swelling and preventing complications. Medications Lymphedema greatly increases the risk of skin infections (cellulitis). Your doctor may prescribe antibiotics for you to keep on hand so that you can start taking them immediately once symptoms appear. Therapy Specialized lymphedema therapists can teach you about techniques and equipment that can help reduce lymphedema swelling. Examples include: • Exercises. Gentle contraction of the mu...

Hi. I'm Dr. Stephen Ansell. I'm a hematologist at Mayo Clinic. In this video, we're going to cover the basics of lymphoma. What is it? Who gets it? The symptoms. Diagnosis and treatment. Whether you're looking for answers for yourself or someone you love, we're here to give you the best information available. Lymphoma is an overarching term for a kind of cancer that starts in the lymphatic system. Cancer diagnosis of any kind can be very difficult to deal with. But recent advances in how we treat lymphoma and ongoing research means there's a lot of hope. Treatment is highly successful for the majority of patients. First, what exactly is the lymphatic system? Well, it's actually a crucial part of the immune system. The lymphatic system produces lymphocytes, or white blood cells, which fight off pathogens, bacteria and the like. There are two types of lymphocytes, T cells and B cells. And lymphoma occurs when one of these types of lymphocytes grow and multiply uncontrollably. Often, these abnormal cells will build up and cause tumors in the lymph nodes, which are actually present throughout your body. And so lymphoma cells can collect anywhere. There are different types of lymphoma, but really two main categories. Firstly, Hodgkin lymphoma. This is an uncommon form of lymphoma identified by the presence of rare large cells, which are called Reed- Sternberg cells. And it usually begins in lymph nodes of the neck, the chest, under the arms, and progresses in an orderly fashion...

What is the lymph system? The lymph (or lymphatic) system is a part of your body’s immune system. It includes a network of lymph vessels and lymph nodes.Lymph vessels are a lot like the veins that collect and carry blood through the body. But instead of carrying blood, these vessels carry the clear watery fluid called lymph.Lymph fluid also contains white blood cells, which help fight infections. Lymph fluid would build up and cause swelling if it were not drained in some way. Lymph vessels draw up the lymph fluid from around the cells to send it towards the chest. There, lymph fluid collects into a large vessel that drains into a blood vessel near the heart. Lymph nodes and what they do Lymph vessels send lymph fluid through nodes throughout the body. Lymph nodes are small struct...
