Lung Cancer Symptoms & HealthyLifestyle Tips

Symptoms

In its early stages, lung cancer usually causes no symptoms. As a result, lung cancer is generally not diagnosed until the disease is relatively advanced. At the time of diagnosis, common symptoms of lung cancer are similar to those of some other respiratory diseases: cough, blood stained sputum, wheezing, and shortness of breath. Lung cancer is sometimes diagnosed from a chest x-ray done for another condition. Pneumonia lasting more than two months may indicate the presence of lung cancer and should be followed-up with further testing. Later symptoms of lung cancer generally result from spread to other parts of the body (metastasis). These symptoms may include chest or shoulder pain, unexplained weight loss, bone pain, hoarseness, headaches, seizures and swelling of the face or neck. Lung cancer is usually a fatal disease, except for the minority of patients diagnosed at the early stages of the disease.

Healthy Lifestyle Tips

The following lifestyle changes have been studied in connection with lung cancer.

Smoking

Cigarette smoking is universally acknowledged to be the leading cause of lung cancer, both in the United States and worldwide. By far the most important way to reduce the risk of lung cancer is to not smoke.¹

Passive smoke

Many studies now show that exposure to passive smoke—the cigarette smoke from others’ cigarettes—significantly increases the risk of lung cancer.² As non-smoking sections of restaurants have nearly the same level of smoke as do the smoking sections, it makes sense to seek restaurants that do not permit any smoking and to avoid bars unless they are also non-smoking establishments.

Other inhalant pollution

Inhalant exposure to diesel exhaust, pitch and tar, dioxin, arsenic, chromium, cadmium, and nickel compounds may also increase the risk of lung cancer.³ Exposure to asbestos is associated with an increased risk of lung cancer.
Radon exposure has been reported to contribute to the risk of lung cancer in the general population.⁴ Radon, a natural radioactive substance, can leak into basements from the surrounding soil. Radon exposure can also occur from the water system of houses, particularly when people take showers. Underground miners are also exposed to varying amounts of radioactivity from radon.
