On radiation therapy for tumor in bronchus, have shortness of breath, heart palpitations on physical exertion. Cause?

I am 3 weeks into radiation therapy to tx a tumor at my left main bronchus , 3 cm from the carina; now noticing shortness of breath accompanied by heart palpitations with physical exertion ie - walking on tread mill for more than 5 minutes at 2 mph. Could the radiation be causing some irritation to the vagus nerve to cause this sypmtom?

Thanks for writing.

It looks like you have had radiation therapy for your tumor in bronchus for a while. Radiation therapy, like other modes of treatment for cancer, has its side effects. It is a highly sophisticated treatment but patient may feel weak for sometime during and after radiation therapy. Looks like you are passing through this phase presently.
You may please take guidance from your doctor before starting any physical exertion.

Hope this helps.
