Lung cancer is one of the leading causes of cancer-related deaths worldwide. It is important to know the early warning signs of lung cancer, as early detection and treatment can increase the chance of survival.

Here are 10 early warning signs of lung cancer:.

Chest Pain

Chest pain can be caused by many things, but it is one of the common signs of lung cancer. The pain can be either sharp or dull, and may be constant or intermittent.

If you experience chest pain that is not related to coughing or breathing, consult your doctor.

Coughing that persists

A cough that lasts for more than three weeks could be a sign of lung cancer. It may worsen over time and is often accompanied by blood or rust-colored phlegm. If you are a smoker or have a history of lung cancer in your family, consult your doctor.

Shortness of Breath

Shortness of breath is a common symptom of lung cancer, particularly if it is persistent and worsens over time. It may be caused by a tumor blocking an airway or by fluid accumulating in the chest.

Wheezing

Wheezing is a high-pitched whistling sound that occurs when you breathe. It is often a sign of a respiratory problem, including lung cancer. If you experience wheezing that does not go away, consult your doctor.

Hoarseness

Hoarseness that persists for more than two weeks could also be a sign of lung cancer. It may be caused by a tumor pressing on the nerve that controls the voice box.

Unexplained Weight Loss

If you experience unexplained weight loss, it could be a sign of lung cancer. Weight loss may occur if the cancer causes a loss of appetite or if it affects the way the body metabolizes nutrients.

Weakness

Weakness, fatigue, and general feeling of being unwell could be a sign of lung cancer. These symptoms may be caused by the cancer itself or by the body’s response to it.

Repeated Respiratory Infections

If you experience frequent respiratory infections, such as bronchitis or pneumonia, it could be a sign of lung cancer. This is because the cancer may weaken the immune system, making it more difficult for the body to fight off infections.

Bone Pain

Lung cancer that spreads to the bones can cause pain in the back, hips, and other areas of the body. If you experience bone pain that is not related to injury or exercise, consult your doctor.

Headaches

Lung cancer that spreads to the brain can cause headaches that persist and do not respond to traditional headache remedies. If you experience persistent headaches, consult your doctor.
