5. Shortness Of Breath
The inability to fill your lungs to capacity and take a normal breath may leave you feeling unnerved. It can affect you to such an extent that it leaves you gasping for air. This too is often palmed off as a symptom of prolonged smoking or a deeper condition like asthma. The last thought is of cancer. Shortness of breath can be caused by the thickening and scarring of the tissue in the lungs, however, the increase in the production of phlegm will also pose a threat.
In instances where the tumor itself blocks the airways or fluid from the tumor builds up in the chest cavity will also leave you feeling short of breath and somewhat winded. Pay attention to your body, notice when you feel this shortness of breath. If it is after doing tasks that you did with ease in the past, it is time to see the doctor.
