CLEVELAND, Ohio (WHDH)– There’s a new device that can better detect a common side effect of cancer treatments.

The condition, called lymphedema, causes painful swelling in the arms, legs and hands after undergoing surgery or radiation. The condition is usually detected using a tape measure, but research from Dr. Chirag Shah, the director of breast radiation oncology for Cleveland Clinic, shows a device that uses electrical currents to find it is more effective.

Doctors hope it will help catch more instances of the condition, which can have a significant impact if untreated.
