Transcutaneous Electrical Nerve Stimulation in Chemotherapy Induced Peripheral Neuropathy in Patients With Stage I-III Early Stage Breast Cancer

This study is testing whether transcutaneous electrical nerve stimulation (TENS) — a gentle electrical stimulation applied to the skin — can relieve nerve pain in the hands and feet caused by taxane chemotherapy (paclitaxel or docetaxel) in breast cancer patients. This side effect is called chemotherapy-induced peripheral neuropathy (CIPN). **You may be eligible if...** - You have stage I–III breast cancer - You are currently receiving paclitaxel or docetaxel chemotherapy and plan to continue during the 2-week treatment - You have at least mild nerve pain (numbness, tingling, or pain) in your hands or feet from chemotherapy - You are 18 or older **You may NOT be eligible if...** - You have skin wounds, swelling, or breakdown where the TENS pads would be placed - You have a history of epilepsy - You have an implanted device such as a pacemaker or pain pump - You have pre-existing nerve damage unrelated to chemotherapy - You are pregnant - You have previously received TENS for this condition Talk to your doctor to see if this trial is right for you.
