Lung cancer can spread to nearly any region of the body, but the most common areas are the lymph nodes, liver, bones, brain, and adrenal glands. Let's take a look at each of these areas separately. Most lung cancers first spread to lymph nodes in the chest near the tumor. As cancer progresses, cancer cells can travel to areas in the chest further from the initial tumor, and then on to other regions of the body.
Small cell lung cancer accounts for 10%â15% of all lung cancers. It usually starts in the bronchi in the centre of the lungs. Small cell lung cancer is the most aggressive of all types of lung cancer.In many cases, it has spread to other parts of the body by the time it is diagnosed. Small cell lung cancer is also known as oat cell carcinoma or small cell undifferentiated carcinoma. Stage is the most important prognostic factor for small cell lung cancer. 2  Limited stage cancers have a much better prognosis than extensive stage cancers. 3  Most people with small cell lung cancer are diagnosed with extensive stage cancer because the cancer spreads early and quickly, before it causes symptoms.
