Causes of Lung Lancer Lung cancer is the major disease around every part of the country and this is increasing nowadays at greater speed. This is seen more common among men and women. There are only 2% of people surviving after diagnosing of cancer at its worst stage that is after spreading to most parts of the body through swelling. In the case of diagnosing at its early stage makes the people to survive for more than 5 years and more and the number of people survive in this case is 49%.

The best example for this kind of spreading in lungs is the prostrate lump which spreads through the bloodstream to the lungs but this is not a lung disease hence proper and well efficient scanning has to be done before treatment. The main reason for occurring of cancer is due to the transformation of cells which undergoes many changes in growth and also lacks in basic habitual reins. These cells which behave differently from others form a group of cells and look different from where it arises and the tumors formed because of this kind of unnecessary growth of cells are very dangerous as they take oxygen, and nutrients from the distant cells which are not affected. This will cause the other cells to die and makes the whole system to work improperly in short period. The main cause for cancer is the use of tobacco and cigarette smoking is one of the main reasons as it uses tobacco leaves. This makes the cells to grow in a rapid manner and this is proved with evidence through research in 1950s. A cigar normally contains 4,000 chemicals which are harmful and it is responsible for causing sarcoma. Also it has proofs that the occurrence of lung cancer to people who are smoking cigarettes in a continuous manner each day has the chance of developing lung disease 20-25 times more than normal people without smoking. But the good news in this developing disease is if a person develops the disease because of continuous smoking and if he quits the habit as a whole after occurring then there are many chances to getting cured off in a whole. Because quitting of smoking makes addition of infected cells to lungs decrease and thus restricts the growth of lungs and even minimize the growth

in a long time gap. Not only cigarette smoking is the cause for lung cancer but also exposure to cigar and channel smoking causes the same, but the percent of causing the lung cancer is more only with cigarette smoking.

This spreads the disease in a rapid way and thus results in more damages in short period. The spreading of tumors is done either by lymph nodes or by bloodstream. This kind of spreading is called as metastasis . This causes the lung melanoma to metastasize and this lump is called as the major lump whereas the tumors in other parts of the body are called as minor tumors or metastasis tumors.

This adenocarcinoma has a subtype and this is called as bronchoalveolar cubicle carcinoma and it creates an appearance like pneumonia in chest x-emission. Another type of NSCLC is squamous unit carcinoma which supports normal lung scourge and this causes nearly 30% of all lung cancers. There is also a large section of melanoma which is also a type of NSCLC responsible for nearly 10% of lung cancers and SCLC alone makes up to 20% of lung cancer cases. Credit: wikimedia.org The lung cancers caused by two groups such as NSCLC and SCLC are nearly 95% and this kind of grouping is done based on the type of cells responsible for the spreading of disease. The remaining 5% is based on the blood group types such as carcinoid growth, lymphoma and the other causes related to blood groups. The two groups that is NSCLC and SCLC are characterized under microscopic scanning and this is called as small faction lung growth and non-small cell lung blight. In this NSCLC have several subtypes of tumors which cause the disease in more number and cannot be diagnosed whereas SCLC type of cancer could be diagnosed. Credit: wikimedia.org Symptoms and Types of lung cancer includes cough , bloody coughing, binding of chest, and breath dumpiness and in case of metastatic lung tumor the symptoms are not predictable as it varies depending on the position and the extent to which it affects. By keen look at the symptoms and by the frequent check up this cancer could be identified. As this is most dangerous disease get into treatment as soon as you came to know about the disease.
