Lung cancer or bronchogenic arcinoma, a life threatening disease, is the uncontrolled growth of abnormal
cells in one or both of the lungs. While normal lung tissue cells reproduce and
develop into healthy lung tissue, these abnormal cells reproduce rapidly and never
grow into normal lung tissue. As a result,
lump mass known as a tumor are formed, disrupting the lungs and making it difficult
to function properly. Tumors can be benign (non-cancerous) or malignant (cancerous).
Benign tumors may grow causing discomfort and bleeding, but they do not spread
to other parts of the body and can be removed.
Malignant tumors grow aggressively,
spread into other areas of the body and destroy normal tissue. The process of
spreading the tumor is called metastasis (secondary tumors) and the areas of tumor
growth at these distant sites are called metastases.
Usually
lung cancer, develops within the wall or epithelium of the bronchial tree. But
it can start anywhere in the lungs and affect any part of the respiratory system.
Lung cancer mostly affect people between the ages of 55 and 65 and often takes
many years to develop. Once it occurs, cancer cells can break away and may spread
to the lymph nodes or other tissues in the chest, including the lung opposite
to where it originated. It may also spread to other organs of the body, such as
the bones, brain or liver.
