Lung Cancer Signs & Symptoms for a Heavy Smoker

Lung cancer kills nearly 162,000 Americans each year, according to the National Cancer Institute (NCI). The NCI estimates that the vast majority of lung cancer cases are directly caused by tobacco smoke. Like many other forms of cancer, lung cancer may not demonstrate many symptoms in its early stages, even in heavy smokers. As the cancer grows, some common symptoms may become apparent.

Coughing

• A constant, frequent cough is one of the most common symptoms of lung cancer. Many heavy smokers may dismiss this constant cough, but it can be a warning sign, especially if you ever cough up blood. Even the smallest amount of blood should be cause for alarm, according to the Mayo Clinic.

Difficulty Breathing

• Troubled breathing is another symptom of lung cancer, according to the NCI, and can be seen in heavy smokers and those who have already quit. You may have difficulty catching your breath on a regular basis or problems with wheezing.

Chest Pain

• Lung cancer may also cause a dull chest pain that does not go away. Dr. Howard Wayne has found that heavy smoking may exacerbate this symptom because smoking increases blood pressure and heart rate.

Lung Infections

• People with lung cancer, and especially heavy smokers, may get frequent lung infections. Numerous bouts of pneumonia or bronchitis can be a sign of lung cancer and the American Cancer Society recommends seeing your doctor if you develop frequent infections.

Weight Loss and Fatigue

• Numerous forms of cancer cause weight loss and fatigue, and lung cancer is no exception, according to the NCI. Heavy smokers may lose weight unexpectedly and have a sudden onset of severe fatigue and weakness that does not go away.
