Types of lung cancer
Small cell lung cancer
Small cell lung cancer, which is often referred to as "oat cell" lung cancer because the cells resemble oats under the microscope, begins in the lung tissue. SCLC often spreads quickly, and accounts for less than 20 percent of lung cancers.
There are two stages of small cell lung cancer: limited and extensive. The stage of small cell lung cancer you have will be determined during the testing and staging process.
Non-small cell lung cancer
Non-small cell lung cancer accounts for nearly nine out of every 10 cases, and usually grows at a slower rate than SCLC.
