How to Measure your Arm

The Cancer Exercise and Physiotherapy Lab (CEPL) has developed a short tutorial to assist people with breast cancer in measuring their arm. Measuring your arm after Breast Cancer treatment is important as it is an indication of whether an individual’s lymphedema self-management strategies are working effectively and helps track the onset of swelling.

Note: The original measuring tape used was the MyoTape Body Tape Measure made by AccuFitness (available on Amazon as of May 2020 at https://www.amazon.com/AccuFitness-MT05-MyoTape-Body-Measure/dp/B000G7YW7Y). We used another model that was less expensive in subsequent studies, but it is no longer available to order. You can find a similar tape using term “body measuring tape” or “body tape measure”.
