Lung Cancer Diagnosis - Symptoms, Stages and Treatment

Ninety per cent of lung cancer diagnosis is connected with smoking. The risk of lung cancer is 30 times greater in habitual smokers than in non-smokers and correlates with the total exposure to cigarettes, referred to as pack-years. One in seven people who smoke at least two packs a day will die of lung cancer. Cigar and pipe smoke double the risk of developing lung cancer, compared to nonsmokers. Exposure to air pollution, radiation and industrial chemicals, such as arsenic, nickel and asbestos also intensify the risk of lung cancer symptoms. Asbestos alone increases by four times the risk of getting the malady. The mixture of asbestos and smoking increase the risk 90 times.

Research workers continue to study the lung cancer diagnosis and to seek the ways to prevent it. They have found several lung cancer causes. Most of them are related to the use of tobacco.

Cigarettes - everybody knows that smoking cigarettes causes lung cancer. Carcinogens (are harmful substances in tobacco) damage the cells in the lungs. As time goes by, the damaged cells may become cancerous. The likelihood that a smoker will develop lung cancer is influenced by the age at which a person begin to smoke, how long a person has smoked, the number of cigarettes he smokes per day.

Environmental tobacco smoke - the chance of developing lung cancer is increased by exposure to so- called, environmental tobacco smoke (ETS) - the smoke in the air when someone else smokes. Such a situation is called involuntary or passive smoking.

Radon - radon is an invisible, odorless, and tasteless radioactive gas that takes place naturally in soil and rocks. It can inflict damage on the lungs that may lead to lung cancer. People who work in mines may be exposed to radon and sometimes radon is found even in houses. Smoking increases the risk of lung cancer diagnosis even more for those already at risk because of exposure to radon. Equipment for the homeowners allows to measure radon levels in their homes and is available at most hardware stores.

Asbestos - asbestos is the name of a group of minerals that happen naturally as fibers. Asbestos fibers tend to break easily into particles that can hold up in the air and stick to clothes. When the particles are drawn in, they can settle in the lungs, damaging cells and increasing the risk for lung cancer diagnosis.

Pollution - explorers have constituted a link between lung cancer and exposure to certain air pollutants, such as by-products of the combustion of diesel and other fossil fuels, though, this connection has not been clearly defined.

Lung diseases - some fixed lung diseases, such as tuberculosis, enlarge a person's chance of evolution lung cancer. Lung cancer tends to develop in are as of the lung that are scarred from TB.

Personal history - a person who has had lung cancer diagnosis once is more likely to develop the second lung cancer compared with a person who has never had lung cancer. Quitting smoking after the disease is diagnosed may avert the development of lung cancer secondly.

Researchers continue to study the causes of lung cancer diagnosis and to search for ways to prevent it. We already know that the best way to prevent lung cancer is to quit (or never start) smoking. The sooner a person quits smoking the better. Even if you have been smoking for many years, it's never too late to benefit from quitting.

The lung cancer symptoms may be as following: persistent chest pain, continued cough that gets worse over time, problems with breath (shortness or wheezing), poor appetite and weight loss, fatigue or even exhaustion, sometimes one can have coughing blood or swelling of the neck and face. But before giving oneself to despair one has to check with a doctor, because these symptoms may be caused not only by lung cancer.
