You Should Know about Overview of Lung Cancer.

By Antin. Do you know that lung cancer is still one of the most prevalent forms of cancer today? Even after all of quitsmoking campaigns and a huge decrease in the number of smokers, it is expected that there will be more than 215,000 new lung cancer cases diagnosed this year, and there will be nearly 162,000 deaths.

Smoking is one of the greatest risk factor of lung cancer. It is estimated that 9 out of 10 lung cancer cases are caused by smoking. The risk of developing lung cancer increases with the number of years they have smoked. The longer they have been smoking, the higher is their risk of developing lung cancer. But cigarette smoking is not the only cause. The risk of lung cancer is also increased for passive smokers who are exposed to tobacco smoke indirectly. Exposure to carcinogens like arsenic, asbestos, chloromethyl ether, radon gas and chromium compounds are another cause of lung cancer.

Women have greater risk to develop lung cancer because they are more prone to develop lung cancer than men are. One study shows that a gene correlate with abnormal cell growth was found to be more active in women than in men whether these women smoked or not. Women who experience oestrogen replacement may be at higher risk of developing lung cancer. As stated by researchers from the University of Pittsburg, the growth of non-small-cell lung cancer may be stimulated by estrogen.

Treatment of lung cancer that range from radiotherapy, chemotherapy to surgery is a painful process for the patient. So prevention is always better than cure. Prevention involves increasing protective factors and decreases risk factors. Protective factors are things that prevent lung cancer from developing such as having a healthy lifestyle.

It is also necessary for people to be aware of various symptoms of lung cancer because It is important to detect lung cancer in early stage. Early detection will affect treatment plan and result. Sometimes lung cancer is already late and cancer has already spread to other part of the body before diagnosis is being made. People that have good knowledge about the possibility and their risk of developing lung cancer will be able to ask for medical check-up and professional opinion early before the lung cancer spread.
