pneumonia, is there a follow up protocol? - 1273387

Hi
I posted a few years ago with a concern about a tiny lesion that turned out to be benign and unchanged - whew!
so relieved. :)
I also mentioned my fears because my mom and dad both had lung cancers, my brother died from ARDS 2/1/14 and well, frankly, anything involving breathing scares me. {ETA: just confirmed with my sister- my mom's first lung cancer was diagnosed when she had a pneumonia one winter that would not go away. Neither of us know if she actually had pneumonia, or if it was "just' the cancer all along. My dad's lung cancer caused no symptoms, it was found on a routine xray}

I was just diagnosed with pneumonia in my left lung (xray was done) and given an antibiotic.I believe they called it "mild", which surprises me considering how awful I feel. After finishing the antibiotic, I have improved, which is a huge relief, of course!! I am still coughing a LOT and still have trouble breathing, but friends who have had pneumonia tell me this is normal (I myself have never had pneumonia before)
I had been sick since Feb11th, got the flu, then just as it seemed to be getting a tiny bit better, got hit with what felt like a second flu, and then just never got any better. Eventually I was having such a hard time breathing, that a friend insisted on taking me to Urgent care where they gave me a nebulizer treatment of some kind, took xrays and sent me home with an antibiotic (zithromax)

Some friends have asked when I will be having a follow up xray, but I was seen in urgent care (I do not currently have a PCP) and there was no mention of any follow up.

is this something that needs to be done? and if so, how long after treatment do you wait before having a second xray?

My initial response to the xray was relief, because to my thinking, anything that's big enough to be seen on an xray is highly unlikely to be cancer,
now, my well meaning friends have re activated my fears of lung cancer and got me wondering if I have any reason to be concerned.
