Testing an abdominal pressure device to reduce lung tumor movement during radiation

This trial is testing whether a special abdominal pressure device can help keep lung tumors still during radiation therapy. When you breathe, your lungs move, which can make it harder for radiation beams to hit the tumor precisely. Researchers want to see if this device can reduce that breathing movement and improve the effectiveness of your treatment.

Lung tumors move with every breath you take, which can make radiation therapy less accurate and potentially less effective. This trial exists to find out whether using an abdominal pressure device during treatment can keep tumors steady, allowing doctors to deliver radiation more precisely to the cancer while protecting healthy tissue.
