Do these symptoms look like lung cancer?
I've been having a really dry cough for a few weeks at least (not that bad but the urge to cough is almost constant.) A bit more mucus is produced. I feel like I'm out of breath even when sitting down, and feel like there's something blocking the airway. There's sometimes a sharp pain at a specific point in my left shoulder or ribs.
I smoke about 12-20 cigarettes a day, but haven't smoked for more than five years, and I'm in my early twenties.
