Smoking and Lung Cancer Warning Signs

There are many different reasons why people get lung cancer. There are several people that get it through the natural aging process of their body and there are also many people that get it through different environmental factors such as contact with asbestos or cigarette smoke. The DNA in our bodies replicate to form new cells everyday. Sometimes those DNA cells mutate and create cancer cells that can be caused by the factors just mentioned.
According to LungCancer.org, Lung Cancer is the number one cause of death from cancer each year in both men and women. Out of the large variety of smoking facts and smoking statistics, this is one of the bold few that stand out the most. Though there are many forms of lung cancer, Primary Lung Cancer is the most common among smokers. It can also be easily avoided if a smoker decides to quit. Smoking a pack of cigarettes each day for an entire year is equal to pouring a cup of tar into your lungs. The potential damage is frightening and the chances of having cells in the lungs that will mutate is greater each year you smoke. The healthy cells in the lungs change dramatically from the effect of cigarette smoke as well. These cells will effect the airways over time. The lungs have a natural system called cilia that swiftly help the body clean the airways. With every inhalation of smoke, those cilia slow down deceasing their effectiveness of function. Every year heavy smokers slowly lose the amount of cilia they have in their lungs. Smoking also causes increased mucus production in the lungs. This is because the the body’s natural response is to increase the size of the lung’s cells. The mucus in a smokers lungs tends to be thicker than normal and when there is too much, infection can take place. Over time the healthy bronchi and bronchioles in the lungs have a harder time trying to deliver rich oxygen to the heart. Emphysema is a common sickness many smokers face as a result. According to the American Lung Association, a big reason why lung cancer is so serious is because it is very hard to detect in the early stages. It can take years for the cancer to grow and when it finally does grow to a large state is when the individual usually starts to experience symptoms.
Though Close to 90% of all Lung Cancers are smoking related, believe it or not their are thousands of smokers that think that smoking doesn’t harm them. Lung Cancer is very preventable. Quitting can save lives.
