You Can Save Patients from Lifelong Lymphedema

A 30-second test can help prevent cancer-related lymphedema

How You Can Help Patients Who Are At Risk

To actually prevent lymphedema, patients need to be identified early and placed on a compression garment protocol ​before​ they develop symptoms. By the time they experience swelling, the condition is typically irreversible. By following a proven prevention protocol, you can help your patients get prompt treatment and maintain a good quality of life.

Unfortunately, Most Tools Can't Reliably Detect Subclinical Lymphedema

Tools like tape measures and perometry lack the accuracy and objective data that are necessary to detect subclinical lymphedema consistently. These technologies rely on significant fluid accumulation to detect measurable increases in limb circumference, and increases in fat and soft tissue that may further complicate interpretation. And when you factor in human variability, these instruments become unreliable.

The ONLY Accurate and Reliable Test for Detecting Subclinical Lymphedema

Today, the only reliable tool we have to spot subclinical lymphedema is bioimpedance spectroscopy (L-Dex®), which measures extracellular fluid. The L-Dex score represents the difference in the amount of extracellular fluid in an at-risk limb compared to an unaffected limb. It uses noninvasive bioimpedance spectroscopy (BIS), which is capable of detecting fluid changes as small as 2.4 tablespoons (36ml).

Lymphedema Prevention Is As Simple As: Test, Trigger, Treat

It’s not possible to predict which patients will develop lymphedema. The L-Dex score, however, was shown in the PREVENT trial to detect lymphedema early enough to treat and prevent it1. That’s why every patient should be tested.



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.



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.



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.

Support a Prevention Program and Help End Cancer-Related Lymphedema

As your patient’s caregiver, you are uniquely positioned to administer the SOZO test and to escalate treatment if the L-Dex score indicates lymphedema is developing. The good news is, we’ve already created the step-by-step playbook for lymphedema prevention. All you need to do is follow it.
