5. Change in voice.
If over time your voice changes to become raspy or deeper, it could mean that lung cancer is effecting your lungs and voice-box. If the change in voice doesn’t go away after about half a month, or two weeks, then it could potentially be something more serious than a typical cold. Chances are that this symptom isn’t going to be too serious, since it often is not the result of lung cancer but it’s better to be safe than sorry.
