Discuss the causes of lung cancer
Lung cancer is one of the most dangerous diseases which make most of the people suffer. Lung cancer has been noted by the Canadian cancer Society (2010) as the most leading one which affected both male and female in 2010 and out of 24,200 Canadians, 20,600 of them died of lung cancer. Like any other types of cancer, lung cancer is basically caused due to the abnormal growth of cells in one of the body parts, lungs. Although the role of genetics is not very popular in lung cancer but the history of lung cancer in families will lead to the high risk of getting lung cancer. Moreover if they were your parents, siblings or child then the chances of getting it is more. Genetics are becoming the most unpreventable factor that will lead to lung cancer. It is unpreventable but if it is detected early, it might help us to reduce the risk of developing cancer cells inside the body. There are three main causes of lung cancer besides genetics including lifestyle, environment and infections. Lifestyle has been carried by people in their life, in their activities, and environment. There is a good lifestyle and bad lifestyle that people practice in their lives. If people follow their good lifestyle then the disease will not happen, but the problem is that many people follow bad lifestyle just because of imitating other people like drinking alcohol, smoking and unhealthy diet. This lifestyle has a bad effect to health especially to lung cancer. Drinking alcohol, smoking and consuming unhealthy diet are the three main factors in lifestyle that leads to lung cancer. The foremost cause of the lung cancer depends on the lifestyle of the people. Drinking alcohol is one of the factors that usually we do not pay much attention. People think that drinking alcohol is one way to relieve stress and to socialize with friends. Drinking alcohol is usually practiced in different situations which are not limited to one event or activity. People usually do not realize that drinking too much alcohol will cause bad effect to the body especially to the lungs which will lead to cancer. Alcohol in here does not mean that pure alcohol or 100% pure; the percentage of alcohol which contains in the beer that people drinks. People usually do not directly drink alcohol but consume it with the other drinks like beer, vodka, etc. Each type of these will have a different amount of alcohol concentration. If you consume a great amount of alcohol then the risk of getting cancer also will be higher, if it is consumed continuously. According to Paolo Boffeta, on his research in American Journal of Clinical Nutrition, he states that if the consumption of alcohol is more than 30 ml per day, then, it will increase the risk of having lung cancer. It is even worse in the case of a bad smoker; it will increase the risk of having lung cancer, because of the chemical reaction in the body between the smoke and alcohol. So, by reducing this habit of drinking will generally help to reduce the risk of lung cancer. The lifestyle of smoking is also another factor of getting lung cancer. High intake of smoke results in a high risk of lung cancer to the people who do not smoke. Smokers can be categorized into two types; they are active smokers and passive smokers. An active smoker will have a higher risk of getting lung cancer than a passive smoker. Passive smokers will still have the possibility to get lung cancer and in addition to this if he inhales the smoke continuously, then he will face a higher risk of getting cancer. An active smoker has the possibility of getting lung cancer but it also depends on the time when he began smoking, how many cigarettes he consumes per day, and how long he has been smoking. The risk will increase if he continues to smoke, but the risk will eventually decrease little by little by the time he stops smoking. The risk of getting lung cancer for both man and woman are the same, although previously it has been said that...
