Shortness of breath
If you’re suffering from sudden shortness of breath, it might be a symptom of lung cancer. Shortness of breath is best described as difficulty in breathing or breathing heavier and faster, in an attempt to get enough air into your lungs.
You’re huffing and puffing as if you just had one hour of cardio. It can happen any time during the day. While shortness of breath may also occur in older people, or in people who are suffering from anxiety or hyperventilation, in 85% of the cases, it is a more worrisome sign. If you’re a smoker and you experience this symptom, it might be a signal of COPD or lung cancer.
