Lymphatic Health Glossary

Essential Terms & Definitions

Understanding lymphatic health terminology helps you communicate with healthcare providers, research conditions, and make informed decisions about your care.

A | B | C | D | E | F | I | L | M | P | S | V

A

Axillary Lymph Nodes

Cluster of lymph nodes in the armpit region. Commonly removed or damaged during breast cancer surgery, leading to arm lymphedema risk.

B

Bromelain

Enzyme derived from pineapple with anti-inflammatory properties. Used in lymphatic supplements to reduce swelling and accelerate healing.

C

CDT (Complete Decongestive Therapy)

Gold standard treatment for lymphedema combining manual lymphatic drainage, compression bandaging, exercises, and skin care. Requires certified therapist.

Cellulitis

Bacterial skin infection that can trigger or worsen lymphedema. Symptoms: redness, warmth, swelling, fever. Requires immediate antibiotic treatment.

Compression Garments

Medical-grade elastic sleeves or stockings that apply graduated pressure to reduce swelling and support lymphatic drainage. Must be professionally fitted.

D

Diuretic

Medication or substance that increases urine production to reduce fluid retention. Generally ineffective for lymphedema but can help regular edema.

Dry Brushing

Technique using natural bristle brush on dry skin to stimulate lymphatic flow. Brush toward heart before showering.

E

Edema

General term for swelling caused by excess fluid in tissues. Can be temporary (from salt, sitting) or chronic (from heart, kidney, liver disease).

Elevation

Positioning limb above heart level to use gravity assisting lymphatic drainage. Recommended 15-20 minutes, 3-4 times daily for swelling reduction.

F

Fibrosis

Thickening and hardening of tissue from chronic inflammation or lymphedema. Advanced stage showing permanent tissue changes.

I

Inguinal Lymph Nodes

Lymph nodes located in the groin area. Removal during cancer surgery increases leg lymphedema risk.

L

Lymph

Clear fluid containing white blood cells, proteins, fats, and waste products that circulates through lymphatic vessels. About 2-4 liters in adult body.

Lymphatic Drainage Massage (MLD)

Specialized gentle massage technique that manually moves lymph fluid toward drainage points. Must be performed by certified therapist for lymphedema.

Lymphatic System

Network of vessels, organs, and tissues that transport lymph, remove waste, and support immune function. Includes lymph vessels, nodes, spleen, thymus, tonsils.

Lymphatic Vessels

Thin-walled tubes carrying lymph fluid throughout body. Unlike blood vessels, they have no central pump—rely on muscle contractions and one-way valves.

Lymphedema

Chronic progressive swelling caused by damaged or dysfunctional lymphatic system. Primary (genetic) or secondary (acquired from surgery, radiation, infection). Requires lifelong management.

Lymph Nodes

Small bean-shaped organs (500-600 in body) that filter lymph and house immune cells. Clustered in neck, armpits, groin, chest, abdomen.

Lymphoscintigraphy

Diagnostic imaging test using radioactive tracer to visualize lymphatic flow and identify blockages. Gold standard for diagnosing lymphedema.

M

Manual Lymphatic Drainage (MLD)

See "Lymphatic Drainage Massage." Specialized hands-on technique moving lymph fluid through gentle rhythmic movements.

mmHg (Millimeters of Mercury)

Unit measuring compression garment pressure. Class 1: 15-20 mmHg (mild), Class 2: 20-30 mmHg (moderate), Class 3: 30-40 mmHg (strong).

P

Pitting Edema

Swelling where pressing thumb into tissue leaves indentation lasting 15+ seconds. Characteristic of regular edema; lymphedema usually non-pitting in advanced stages.

Primary Lymphedema

Rare genetic condition (1 in 6,000-10,000 births) where lymphatic system doesn't develop properly. Swelling present at birth or appears during childhood/puberty.

S

Secondary Lymphedema

Most common type of lymphedema. Develops after damage to previously normal lymphatic system—from cancer surgery, radiation, infection, trauma, or obesity.

Sentinel Lymph Node

First lymph node(s) where cancer is likely to spread. Often removed during cancer surgery and tested. Removal carries 5-10% lymphedema risk.

Stemmer's Sign

Diagnostic test for lymphedema. Inability to pinch/lift skin on top of second toe or finger indicates thickened tissue from lymphedema. Positive sign confirms diagnosis.

V

Venous Insufficiency

Condition where leg veins can't pump blood back to heart efficiently, causing pooling and swelling. Often coexists with lymphatic dysfunction. Causes varicose veins.
