Lung cancer is the most common cause of cancer-related deaths worldwide. It is called a “silent killer” because it often shows no symptoms until it has progressed to an advanced stage.

Early diagnosis can give you a greater chance of survival, so it’s important to know the signs and risk factors of lung cancer.

Risk Factors of Lung Cancer

Smoking is the primary cause of lung cancer, with smokers having a higher risk of developing lung cancer compared to non-smokers.

Exposure to second-hand smoke, radon, air pollution and workplace hazards such as asbestos and diesel exhaust can also increase your risk of lung cancer.

Signs of Lung Cancer

Here are seven common signs of lung cancer you should be aware of:.

1. Persistent Cough

A persistent cough that lasts for more than two weeks is a common symptom of lung cancer. The cough may be dry or produce mucus and may worsen over time.

You should consult your doctor if you have a persistent cough, especially if you are a smoker or have been exposed to other risk factors.

2. Shortness of Breath

Shortness of breath can be another sign of lung cancer. This occurs when a tumor blocks or narrows an airway, causing difficulty in breathing.

You may experience wheezing or feel out of breath even when performing simple tasks that you previously found easy.

3. Chest Pain

Lung cancer can cause pain in your chest, shoulder, or back. The pain may be sharp, dull, constant, or intermittent. It may also worsen with deep breathing, coughing, or laughing.

4. Unexplained Weight Loss

Unexplained weight loss can be a sign of lung cancer. It may be unintentional or occur despite eating a normal amount of food. If you have lost 10 pounds or more without trying, talk to your healthcare provider.

5. Fatigue

Fatigue or weakness can be a symptom of lung cancer. It may be caused by cancer itself, or the body’s immune response to it. If you feel tired all the time, even after rest, make an appointment with your doctor.

6. Hoarse Voice

Lung cancer can also affect your voice. A hoarse or raspy voice can occur when a tumor presses against or infiltrates the nerve that controls your vocal cords. If you have a hoarse voice that lasts for more than two weeks, see your healthcare provider.

7. Clubbing

Clubbing is a condition where the tip of your fingers become wider and the nails curve around your fingertips. It can occur due to decreased oxygen levels in your blood, which can be caused by lung cancer.

If you experience clubbing, see your healthcare provider.

Conclusion

Lung cancer is a serious illness that can be fatal if left undiagnosed or untreated. If you have any of the signs or symptoms listed above, make an appointment with your doctor to undergo further testing.

Early detection can help increase your chances of successful treatment and recovery.
