There are three main types of lung cancer: small cell, large cell, and adenocarcinoma. While each has unique hallmarks and treatments, all are alike in that they do not present with many early symptoms. This is unfortunate because the earlier medical practitioners can catch lung cancer, the more effective the treatment. Knowing what to look for and getting to a doctor early is essential for the best results.

1. Timing of Signs and Symptoms

Because most lung cancers do not have many early symptoms, it can be difficult for a doctor to catch the disease before it spreads. People who know they have risk factors for lung cancer should pay close attention to the warning signs. Risk factors include a history of smoking tobacco, exposure to second-hand smoke, exposure to toxic compounds such as arsenic and asbestos, and a family history of lung cancer.
