Lung cancer is a disease caused by uncontrolled cell growth in the lungs. Smoking is the number one cause of lung cancer, accounting for about 87% of all lung cancer cases diagnosed.

In addition to smoking, there are other causes of this disease like radon gas from the earths crust, asbestos and various viruses like the human papillomavirus, JC virus, simian virus 40 (SV40), BK virus and cytomegalovirus.
The specific noticeable lung cancer symptoms include the dyspnea or shortness of breath, hemoptysis or coughing up blood, chronic coughing, wheezing, chest or abdominal pain, weight loss, fatigue, and difficulty in swallowing. Cancer cells may grow in our airway, obstructive airflow and cause dangerous breathing difficulties.

Surprisingly, lung cancer is often diagnosed after the patients going in thinking they have pneumonia.
There are also many non-specific symptoms of lung cancer as well. These symptoms include bone pain, fever and weight loss. Lung cancer often spread to other parts of the body as well, including the bone, spinal cord, liver and the brain. This act of the cancer spreading is known as metastasis.
