Cough lasts

We often experience colds and cough during that time. But if you have a cough that lasts for 3 consecutive weeks without a cold, this is probably an early sign of lung cancer.

Wheeze

When the airway is inflamed, you will wheeze or make a sound as soon as you breathe. The most common causes of wheezing are asthma and allergies.

Shortness of breath

Difficulty breathing, shortness of breath is a sign of lung cancer. 9/10 people with lung cancer will show this warning sign.

Shortness of breath can also be caused by arterial occlusion, anemia, respiratory infection, chronic bronchitis, overtraining or lack of oxygen to breathe in very high areas. Therefore, it is normal for you to feel short of breath when you do not have enough oxygen and your lungs try to make up for it, leading to difficulty breathing.

However, if breathing difficulties are caused by blockage in the airways or fluid builds up in a lung tumor, you have lung cancer. If you suddenly find it difficult to breathe when doing something that you used to do is too simple, go to the doctor immediately.
