I'm going out my mind.. CANCER..Honestly..someone help. are there any other things that could happen that shows as a mass on someones chest xray?

It is ony small looking on the xray but theyre doing tests and stuff and I am breaking my heart. :'(

He's had a pain in his chest at the left side near his ribs for over a week and we have been trying to get him to go to docs and we only managed yesterday.

He was sick today apparantly in hospital and it was pinky and thick and yesterday he had been coughing up blood..

I tried asking him what they thought it could be and they said that he had been for a scan and more blood tests and that they were gonna put him on iv drip things and that it could be a few things like a clot or something but I think he is masking stuff

Me and my mum are besides ourselves.

He has emphasema also and asthma. :'(

I keep breaking down but trying not to infront of my dad. Trying to be positive etc but it's hard. I hope he is okay. I have forgot why I wrote this now.
