LUNG CANCER DESCRIPTION
Lung cancer refers to the cancer of the lungs where the cells are subject to abnormal growth and division. The body always keeps a check on the normal growth of the cells. If there is disruption in this system, it may lead to cancer in the long run. As a result there is uncontrolled division and proliferation of cells in the lungs which may lead to tumor in the lungs.
Tumors in the lungs can be malignant or benign. The benign tumors can be removed surgically. The malignant tumors on the other hand grow very fast and may start spreading to and invading the other parts of the body. As a result the tumor cells enter into the blood stream as well. Lung cancer is a very life threatening type of cancer as the spread of cancer is very fast. Lung cancer, if left untreated can quickly pass on to other parts of the body such as glands, brain, liver and bone.
The lung is also a very common site of the tumor to spread from other parts of the body as well. Lung cancer can begin in any part of the lungs. Majority of the lung cancers arise from the lining of cells that connect the bronchi and the bronchioles. Lung cancers can also arise from the surrounding tissues as well as the blood vessels.
Lung cancer is one of the most common types of cancer found in men and women throughout the world. Lung cancer was not very common before the 1930s but the cases throughout the world increased at a brisk pace as people started to consume tobacco in different forms. Hence many countries are now publicly addressing the harmful effects of tobacco and tobacco related products. Lung cancer remains the most common type of cancer in men and the fifth common type of cancer in women.
Reasons for lung cancer
90% of all lung cancers happen due to smoking. The risk of a person getting lung cancer increases with the amount of cigarettes smoked as well as the years for which cigarettes are smoked. There are about 4,000 dangerous chemicals found in tobacco smoke including nicotine, tar and carbon monoxide.
Passive smoking refers to inhalation of tobacco smoke because of other people smoking nearby. Studies show that non smokers who are in close proximity with smokers regularly are very much subject to getting lung cancer.
People who are subject to air pollution are also susceptible to lung cancer. 1% of lung cancer deaths are due to air pollution.
