Lung cancer is one of the leading cancers that affect both men and women. The most common risk factor associated with lung cancer is smoking. As a matter of fact, smoking cigarettes, pipes, or cigars account for 90 percent of lung cancer cases.
Lung cancer can also be asymptomatic at first and when symptoms appear, the cancer is often in the advanced stage. An oncologist and pulmonologist usually work together in handling patients with lung cancer.
