What is Lung Cancer?

Lung cancer is the most frequent cause of cancer-related death in both women and men. Smoking tobacco or breathing in substances like diesel exhaust, asbestos, and radon may cause lung cancer. Other risks include an ancestor with cancer, having an extended family history of lung cancer, and having had radiation therapy in the chest in the past.

Signs and Symptoms

Many people suffering from lung cancer do not experience any symptoms whatsoever. They are diagnosed when their doctor examines them or scans their body for another condition.

Adenocarcinoma for instance, may develop in the outer regions and cause back pain. Squamous cell cancer however grows in the middle lung and causes discomfort in the chest area. Cancer that has spread to bones may also produce bone pain, especially in the ribs and the spine.

If the cancer is restricted to one part of the lungs, radiation or surgery could be an alternative. If the cancer has spread to other parts of the body, chemotherapy is usually employed.

Diagnosis
