I'm 50, male, ex-light smoker. I had chronic cough for 2 months, mucus, chest pain recently and fatigue. I went to Drs before and they gave me antibiotics but it didn't help. Went again last week and got a chest X-ray that found mass or something abnormal, and Dr gave me stronger antibiotics and said if it doesn't get better to get a CT. Antibiotics haven't worked but Dr is away this week, and I need some ease of mind. Can it be anything but cancer? Can't find any diseases online that match up and explain why the antibiotics haven't worked.
