Lungs are one of the biggest organs in a human body. Separated into two sections, the left and right lungs, they perform THE most important task for life – breaking down the air we breathe to give every human the needed oxygen for survival. So what is lung cancer? The cells in each lung, and the whole body for that matter, go through the usual life cycle of living and dying. It is when old cells die that new cells should be formed to take their place. In the case of lung cancer, cells keep producing new cells when the other cells are perfectly normal, which means there is an excess of cells in a particular area of the lung. These cells would not have room to be present, and they also have no function as they would not be able to specialize into the different types of cells because there is no reason for them to. Because of this there is an influx of cells in the lung, which cause a mass of cells, better known as a tumor, to be formed. Tumors can be of two kinds – benign or malignant. Benign tumors pose no harm to the person as they do not spread and do not interfere with the usual processes of the body. Malignant tumors in the lung are what we call lung cancer. These malignant tumors can cause harm to the person, and could cause more harm by spreading throughout the body through the lymph system to other parts of the body. Tobacco use is said to be one of the biggest reasons for lung cancer. The worst part is that you do not have to be a smoker yourself to be affected. Second hand smoking can have the same effect. So if you live with someone who smokes a lot, work in an area where there are lots of smokers around, or are in any way in the presence of smoke from a cigarette, you are at the same risk that the person who is smoking is in. Tobacco is said to have carcinogens, which increase the chances of cells acting in the abnormal way to produce a tumor. There have been many lawsuits against tobacco companies as they are not said to have made the impact tobacco has in the causation of lung cancer clear for the public. It is now the law that every cigarette packet should have a warning in bold letters mentioning how ‘tobacco is harmful to health’. Treatment for lung cancer can vary according to how far the tumor has spread, or how much of an area is affected. Doctor’s would prescribe one or a combination of the following few as treatment methods, depending on each individual. Surgery, radiation therapy and chemotherapy are some of the most common treatments for lung cancer. But always remember, the fastest cure to lung cancer, or any other disease, is a positive frame of mind!
