Lung cancer

Lung cancer affects a huge number of population each year. Although cigarette smoking is the main cause, anyone can develop lung cancer. Lung cancer begins when cells in the lung change and grow uncontrollably, forming a mass called a tumor, a lesion or a nodule. A lung tumor can begin anywhere in the lung. A tumor can be cancerous or benign. Once a cancerous lung tumor grows, it may or may not shed cancer cells. These cells can be carried away in blood or float away in the fluid, called lymph, that surrounds lung tissue.The natural flow of lymph out of the lungs is toward the center of the chest which explains why lung cancer often spreads there first. When a cancer cell moves into a lymph node or to a distant part of the body through the bloodstream, it is called metastasis.
