A new study is casting doubt on a controversial lung cancer treatment for older patients called postoperative radiotherapy, or port.

It involves giving radiation with a certain type and stage of lung cancer.

It is thought to cut the chances that a tumor will return.

A new study finds it can damage the heart and lungs, which might cancel out any potential benefits, especially in seniors.

The findings in the journal Cancer Online fuel an ongoing debate over how much treatment older cancer patients should get.

Scientists were unable to find a survival benefit linked to this treatment after surgery.
