Lung cancer is divided into two categories, small cell lung cancer and nonsmall cell lung cancer, depending on how the cells look under a microscope, explains WebMD. SCLC is more aggressive, though rarer, occurring in 10 to 15 percent of cases. Small cell lung cancers have a very strong correlation with smoking, with 99 percent of cases occurring in smokers. These cancers metastasize and spread rapidly, often only discovered after spreading throughout the body.

Nonsmall cell lung cancers are far more common and are divided into three categories: adenocarcinoma, squamous cell carcinoma and large cell carcinoma, WebMD reports. While these three types of lung cancers differ in the type of cell found in the cancer, they share the tendency to spread to the lymph nodes as well as occasionally to other regions of the body.

The symptoms of bronchogenic carcinoma include respiratory difficulties such as shortness of breath, chronic coughing and weakness, according to Loyola University Stritch School of Medicine.
