Let’s End Cancer-Related Lymphedema Through Prevention

Help Prevent Cancer-Related Lymphedema with a 30-second Test

SOZO® with L-Dex® delivers a precise fluid measurement reading quickly at the point of care. With periodic testing following cancer treatment, high-risk patients may be placed on a compression treatment protocol at the earliest possible stage to prevent the condition from progressing.

Help Cancer Survivors Avoid Chronic Secondary Lymphedema

Nurse Practitioners

Introduce lymphedema prevention protocol immediately upon cancer diagnosis to prevent lymphedema progression and improve quality of life in cancer survivors.


Provide more effective lymphedema treatment solutions for patients in the subclinical and stage 1 levels of lymphedema.

Medical Assistants

Get reliable, accurate noninvasive fluid measurement results in about 30 seconds using SOZO® with L-Dex®.

Detect Lymphedema Early and Intervene to Avoid Progression

Accurately Measure & Monitor Patient Fluid Status with L-Dex

SOZO® incorporates L-Dex® technology and bioimpedance spectroscopy (BIS) to quickly and easily provide an accurate measurement of fluid status – the L-Dex score. The L-Dex score represents the difference in the amount of extracellular fluid in an at-risk limb compared to an unaffected limb.

Capture & Share a Patient L-Dex® Score in Seconds

SOZO® allows medical staff in hospitals and cancer clinics to test patients at any location and immediately share that information with surgeons, oncologists, nurse practitioners, therapists and other members of the care team.

Compression Garments Help Control Lymphedema Progression

L-Dex® Testing Paired with Compression Therapy Can Reduce Lymphedema Progression

Clinical data shows that prescribed compression therapy combined with periodic L-Dex® testing has been shown to reduce the progression of lymphedema by 95% in breast cancer patients1.

Guidelines for Lymphedema Prevention

A Lymphedema Prevention Program Gives Hope to Cancer Patients


Test Upon Diagnosis & Periodically after Cancer Surgery

Once a patient has been diagnosed with breast cancer, melanoma, or pelvic area cancers, they will be tested by a member of your staff to record a baseline L-Dex® score. The test itself takes less than 30 seconds and provides an ​immediate​ reading. After cancer surgery, patients should get tested every 3 months for the first 3 years, every 6 months for years 4 and 5, and annually thereafter2.


Evaluate Elevated L-Dex® Readings above the Baseline

Evidence shows that if a patient’s L-Dex® score increases 6.5 or more from the baseline, that’s a “trigger” to evaluate the patient and initiate intervention1.


Apply Treatment to Reduce Lymphedema Progression

Treatment for patients diagnosed with early lymphedema, including standard compression garments worn at home for 4 weeks, 12 hours per day, has been shown to reduce the progression of lymphedema by 95% in breast cancer patients​1.

Recommend a Lymphedema Prevention Program for Your Cancer Clinic or Private Practice

ImpediMed has created a step-by-step playbook for lymphedema prevention to help caregivers administer the SOZO® test and to escalate treatment if the L-Dex® score indicates lymphedema may be developing.
