11 Common Warning Signs of Lung Cancer

Lung cancer is one of the most common types of cancer, and it affects millions of people each year. It’s important to be aware of the warning signs of lung cancer, as early detection can greatly improve the chances of successful treatment. Here are 11 common warning signs that may indicate the presence of lung cancer.

A persistent cough that lingers for several weeks or worsens over time can be a sign of lung cancer. This cough may produce blood or a rusty-colored sputum.

Unexplained shortness of breath, especially if it occurs during normal daily activities, could be a symptom of lung cancer. This can be caused by a tumor obstructing the airway.

Chest pain that is constant and worsens with deep breathing, coughing, or laughing may be a symptom of lung cancer. This can occur when the cancer has spread to the chest wall, causing discomfort.

A persistent hoarse voice that does not improve over a few weeks could be a sign of lung cancer. This may be due to a tumor pressing on the nerve that controls the larynx.

Unintentional weight loss of more than 10 pounds can be a warning sign of various types of cancer, including lung cancer. This weight loss may occur despite eating the same amount or even more than usual.

Lung cancer that has spread to the bones can cause bone pain, especially in the back or hips. This pain may worsen at night and may be a sign that the cancer has metastasized.

Lung cancer that has spread to the brain may cause a variety of symptoms, including headaches. These headaches may be new, persistent, and are not relieved by over-the-counter medications.

Persistent fatigue or weakness that does not improve with rest can be a symptom of lung cancer. This fatigue may be caused by the cancer itself or by the body’s immune response to the cancer.

Frequent respiratory infections such as bronchitis or pneumonia may be a sign of lung cancer, especially if they do not fully resolve or if they recur frequently.

Wheezing that does not improve with asthma or other standard treatments may be a sign of lung cancer. This may be caused by a tumor obstructing the airway.

When a patient starts experiencing new chest pain, particularly if it is severe and does not resolve, it may be a symptom of lung cancer. Pain in the chest may occur when the cancer has spread to the lining of the lungs or chest wall.
