Sticky sensors could help cancer survivors detect arm swelling at home

This study tested new adhesive sensors that stick to the skin to see if they can detect early signs of lymphedema, a painful arm swelling that can happen after cancer treatment. Researchers compared readings from 76 people with and without lymphedema. The goal is to create a simple way for patients to check for lymphedema at home, so it can be treated early when it's more manageable.
