Lung Cancer is a disease caused by uncontrolled malignant cell growth in the tissues of one or both lungs. The lung is the respiratory organ which has a left portion consisting of two lobes and a right portion with three lobes. Lung cancer is one of the most common forms of cancer (death related) to occur in men , and the second most common form in women. The two primary types of this cancer are small cell lung cancer (SCLC) and non-small lung cell cancer (NSCLC).

Small Cell Lung Cancer

SCLC is the least common form of the two and accounts for approximately 17% of all cases of lung cancer. SCLC may also be referred to by a physician as “oat cell carcinoma”. This form of cancer usually develops in the larger air passageways of the lung(s), and grows more rapidly then NSCLC. Their is a strong link between small cell lung cancer and smoking. While chemotherapy is more effective with SCLC (vs. NSCLC), this form is usually more agressive than non-small cell, and typically results in a worse prognosis.

Non-Small Cell Lung Cancer (NSCLC)

NSLC accounts for about 83% of all reported cases of lung cancer.
