The diaphragm move so that the lungs can fill with air and empty. Diaphragmatic paralysis is a condition where this nerve is not working properly. In many instances the cause is never found. It can occur on its own. It can follow surgery, like you had to treat your cancer 6 months ago. During the surgery the nerve may have been irritated or cut or destroyed. This may be seen with a CT scan. If the nerve was just irritated by the surgery, over time your diaphragm may get better.
When the phrenic nerve doesn’t begin to work on its own, as long as it was not cut or destroyed, a surgery called diaphragmatic plication may fix your diaphragm so that it works better. After this surgery people have had less shortness of breath and better pulmonary function tests.
