Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
Non-Small Cell Lung Cancer
- Adenocarcinoma, the most common form of lung cancer in the United States among both men and women;
- Squamous cell carcinoma, which accounts for 25 percent of all lung cancers;
- Large cell carcinoma, which accounts for about 10 percent of NSCLC tumors.
STAGES OF NON-SMALL CELL LUNG CANCER
- If the cancer has spread only to lymph nodes on the same side of the chest where the cancer started, it is called stage IIIA.
- If the cancer has spread to the lymph nodes on the opposite side of the chest, or above the collar bone, it is called stage IIIB.
