Lung cancer is one of the most lethal cancers, with a five-year survival rate of just 19%. In many cases, the cancer has already spread by the time it is diagnosed, making it harder to treat.

However, early detection can improve your chances of successfully treating lung cancer. Here are 7 signs of lung cancer that shouldn’t be overlooked:.

1. A persistent cough that doesn’t go away

One of the most common symptoms of lung cancer is a persistent cough that lasts for more than 2-3 weeks. The cough may produce sputum or blood, and it may feel like a chronic bronchitis.

If you notice any changes in your cough pattern, it’s best to consult your doctor.

2. Shortness of breath or wheezing

Shortness of breath or wheezing can be a sign of airflow obstruction, which may be caused by lung cancer. This symptom is often accompanied by a persistent cough.

3. Chest pain that worsens with deep breathing, laughing, or coughing

Chest pain that is dull or sharp and worsens when you take deep breaths, laugh, or cough can be a sign of lung cancer.

This symptom can also be caused by other conditions, such as bronchitis or pneumonia, but it’s important to get it checked out by your doctor to rule out cancer.

4. Unexplained weight loss

Unexplained weight loss may be a sign of cancer, including lung cancer. This symptom occurs because cancer cells can use up more of your body’s energy, leading to weight loss.

If you’ve lost weight without trying, it’s important to speak with your doctor.

5. Fatigue or weakness

Feeling tired or weak all the time can be a sign of many illnesses, including lung cancer. Cancer cells use up the body’s energy, making you feel fatigued or weak.

6. Hoarseness

If your voice becomes hoarse or if you experience sudden changes in your voice, this may be a symptom of lung cancer.

This symptom occurs because the tumor may press against the vocal cords or the nerve that controls the vocal cords, leading to vocal changes.

7. Bone pain or headache

In advanced stages of lung cancer, the cancer may spread to other parts of the body, causing bone pain or headache. This can be a sign that the cancer has metastasized and requires immediate treatment.

Conclusion

If you experience any of these symptoms, it’s important to see your doctor right away. Early detection can improve your chances of successfully treating lung cancer.

If you have a history of smoking or have been exposed to tobacco smoke, you may be at higher risk for lung cancer. Speak to your doctor about your risk and the best screening options for you.
