In the months, even years after surgery, patients still have to worry about developing a condition called lymphedema.
Fluid builds up in the arm after lymph nodes are removed -- restricting motion and causing painful swelling that can be extreme and very noticeable.
Now doctors at Montefiore Einstein Center for Cancer Care in New York are testing a new device that could pick up early signs of the condition.
The L-Dex uses pads like those used with an EKG. then a weak electrical current goes through the arm and measures any increases in fluid.
Doctors say it's the same current you would feel and perceive if you held a double-A battery between two fingers so it's minimal .
If the L-Dex shows there's extra fluid, doctors can begin early treatments to keep the condition under control. Treatments for lymphadema include massage and compression garments.
