Essay on Smoking and Lung Cancer
Essay on Smoking and Lung Cancer
Smoking has become a common habit for many people all over the world. It has become an addiction to some even if measures by the government to make cigarettes more expensive have already been implemented. What is ironic is that even if people are aware of the negative health effects of smoking, the smokers still do not seem to care. The feeling must be so great when smoking that it’s hard to stop it once a person starts to do it. However, what is also undeniable is that smoking is a direct cause of lung cancer, and lung cancer is one of the most common causes of deaths all over the world (Anderson, 2005). This fact must be more than enough for smokers to finally give up this deadly habit before it’s too late.
It is easy to understand as to why smoking causes lung cancer. It has been discovered that more than forty carcinogens are present in a cigarette. Thus, people who are heavy smokers also have a higher risk of getting lung cancer in the long run. What makes cigarettes very addicting is the substance known as nicotine. Once a cigarette is smoked, the nicotine helps to provide somewhat a calming and relaxing feeling to the smoker. The nicotine also sends a signal to the brain to urge the smoker to smoke another cigarette (Slovic, 2001). Over time, smokers do not realize that what used to be a habit of smoking just one cigarette per day has become one pack per day, and this steadily increases until addiction sets in. This is how addicting cigarettes can really be, and it is extremely hard to stop this habit once people have become heavy smokers. Sadly, the lungs can only absorb a certain level of damage, and once their defences fall apart the heavy smokers have to deal with lung cancer.
People with lung cancer because of heavy smoking usually are not able to breathe properly because their lungs have been extensively damaged already by the harmful substances found in the cigarette. These substances get deposited in the lungs and its alveoli and clog the airways, thus preventing effective breathing. Images of people with lung cancer show that the lungs look burned like charcoal. This indicates the heavy punishment that the lungs had to deal with just so the person can smoke cigarettes and feel better. Just like with any type of cancer, if the lung cancer is detected early, it can be possible that the situation can be reversed and cured eventually (Hyde, 2006). Chemotherapy can be done immediately to eliminate the cancer cells in the lungs. However, most heavy smokers usually ignore the warning signs that they already have lung cancer. They will refuse to consult the doctor even if they are already coughing blood and have difficulty in breathing. Once they finally decide to consult the doctor, it is already too late as the lung cancer is already in its serious stage and treatment is useless.
It is a pitiful sight to see people with lung cancer struggling to breath and looking pathetic when there was a time when they were so strong and lively. What makes this even more frustrating is that this was caused by a simple stick of cigarette that can be easily bought anywhere. These people knew the negative effects in health by cigarettes, but still they went on and smoked heavily (Keyishan, 2003). Thus, these people are merely paying the price for their lack of discipline and commitment to resist the temptation of smoking. For those who are planning to quit smoking but are still hesitating to do so, it’s about time that they find the courage to stop this habit because they will surely suffer the same fate as those people who died of lung cancer.
