Should one have radiation when diagnosed with pneumonia?

I was diagnosed with pneumonia today and I've been getting radiation for my left breast for cancer for the last three weeks.  First, did the radiation weaken my lungs to make me getting pneumonia easier? Secondly should I continue with the radiation while taking antibiotics or wait until I'm over the medicine or just the 48 hours that the doctor said I would be contagious?

Dear Pizmo9, Treatment for cancer can put you at increased risk for conditions such as pneumonia.  The decision as to when to resume radiation therapy should be be made in consultation with your radiation oncologist who will advise based on your overall clinical condition.

I am not a doctor but I have Googled your question and this is what I found:
"Pneumonia in children and adults is caused by bacteria, virus, fungi or protozoa. Out of these, bacteria are the most common microorganisms, that have been found to cause pneumonia. These microorganisms usually enter the body through mouth, nose and eyes, and then infect the lungs, especially the air sacs or alveoli of the lungs. Pneumonia is more commonly found to affect the lower lobes of the lungs. Apart from microorganisms, pneumonia can also be caused by any injury or damage to the lungs, caused by the exposure to certain chemicals and radiation. So, many times, people receiving aspiration or radiation therapy can too get pneumonia". This is the link:

It is your doctor or Radiotherapist who should say what you are to do now, if you continue with radiation while on meds for pneumonia or if you do something else. Said doctors are the only ones who should tell you what to do. Please don't make any decisions on your own.

Take care and get well.
