Eh, that doctor sounds like a moron. You don't look at a patient for a little while in the ER, conclude that they must have lung cancer based on the handful of tests you've done, ask the family if the guy was a smoker, and upon having your suspicions confirmed, saying "Yup. He has teh cancar."
Guess what. You don't suddenly "have trouble breathing" when lung cancer has "spread through both your lungs." It's a slow, debilitating process and your father would have been flat on his back weeks earlier. Nobody has woken up one day to suddenly discover that they have developed terminal cancer overnight throughout a major organ without experiencing some painful symptoms beforehand.
Pneumonia shows up as giant cloudy spots in x-rays, and it
can appear literally within hours. I saw my x-rays last year when I had pneumonia. What a coincidence that lung cancer appears similar.
Hooray to God for crappy doctors that jump the gun!
