==== ====i just collected some highlights about the cancer disease i felt to put it as an article cause its mostimportant to underrated this disease and how to treat ithttp://googleta.com/what-is-cancer/==== ====General Information on Lung CancerLung cancer, or carcinoma of the lung, is one of the most common forms of cancer today. It is oneof the most frequent causes of cancer-related mortality in the United States today. In the UnitedStates, another form of cancer that is becoming increasingly common is breast cancer, which isthe development of malignant tissue in the breast. Breast cancer is seen mostly in women, thoughthis does not mean that men are immune to it. A small percentage of men too contract breastcancer. The numbers are small, 1 man with breast cancer against a 100 women with it, but itsthere. However, there is one major difference between breast cancer and lung cancer. One cansee the symptoms of breast cancer at an early stage, while in the case of lung cancer, thesymptoms are not detected early, primarily because they match the symptoms of other lesserailments. In this article, we will discuss lung cancer.A person is said to suffer from lung cancer when a growth of malignant cancer cells is detected inthe lungs. Depending on the stage at which lung cancer is detected, it can be classified as being inthe:oEarly stagesoMid-stagesoAdvanced stagesToday, there is a vast amount of information on lung cancer available. Patients or relatives ofpatients can access information over the Internet, which has an almost limitless number ofwebsites dedicated to different aspects of lung cancer - types, causes, symptoms, diagnosis,treatment, etc. For example, if you are from the United Kingdom and want to research informationon lung cancer treatment, facilities, etc in your country, you can simply log onto the website ofCancer Research UK, UKs leading cancer charity, and collect whatever information you want fromtheir site.Earlier on, treatment of lung cancer was not an easy thing to do, owing to the huge amount ofexpenses in the form of medical bills, hospital stays fees, etc. However, nowadays with theavailability of insurance, things have become easier. Lung cancer insurance is available easily, asis insurance covering other forms of cancer.Types of Lung Cancer
Two main types of lung cancer exist today. Both of these are seen in the epithelial cells of thelungs. They are:oSmall cell lung cancer (SLCC)oNon-small cell lung cancerThere is another type, called mixed small cell/large cell lung cancer. In this type you can find bothkinds of cells in the cancerous tissue.Besides these two types, there is another form of cancer of the lung area, called mesothelioma ormesothelioma cancer or cancer of the mesothelium. However, this is not considered a primaryform of lung cancer, as its target area is not the lobes of the lung, but the pleural membranecovering the lung.Small Cell Lung CancerThis is the rarer of the two basic forms of lung cancer. One out of every five lung cancer patientssuffer from small cell lung cancer.Non-Small Cell Lung CancerNon-small cell lung cancer, or non-small lung cancer, is the more common of the two basic formsof lung cancer. Four out of five lung cancer patients suffer from this type of cancer.Based on the cell type/area in which the carcinogenic cells proliferate in the lungs, non-small celllung cancer is further categorized into three types. They are:oSquamous cell carcinomaoAdenocarcinomaoLarge Cell CarcinomaoBronchioalveolar Carcinoma (BAC)Squamous Cell CarcinomaThis is the most common type of lung cancer. It occurs in the cells lining the airways inside thelungs. This form of cancer occurs mostly due to nicotine ingestion through smoking.AdenocarcinomaThis form of cancer is seen in the mucus cells within the airways in the lung.Large Cell CarcinomaThis is also called undifferentiated lung cancer. In large cell carcinoma, the proliferating cells are
round and much larger than the cells seen in adenocarcinoma or squamous cell carcinoma.Bronchioalveolar Carcinoma (BAC)This form of cancer is seen in the bronchioalveolar region of the lung.What Causes Lung Cancer?The main cause of lung cancer is exposure to tobacco. This is primarily through smoking. About80% of lung cancer patients are smokers. Smokers may be cigarette smokers, cigar smokers, orpipe smokers; it doesnt matter. The risk of contracting lung cancer is equal in all the three cases.A person may inhale smoke directly. A person can also inhale smoke passively or involuntarily.This smoke is also called secondhand smoke. Secondhand smoke is of two types:oMainstream - This is the smoke exhaled by the smoker, and amounts to more than 50% of allsecondhand smoke.oSidestream - This is the smoke emanating from the burning end of a cigarette/cigar/pipe/hookah.Passive smokers too stand a high chance of contracting lung cancer. The chances ofpassive/secondary smokers contracting lung cancer is 30% higher than people who do not inhalesmoke either actively or passively.However, there have been instances of even total non-smokers suffering from lung cancer. Thisindicates that smoking is not the only cause for lung cancer. It is the primary cause, yes, but notdefinitely the only cause. The following are some of the other causes of lung cancer:oAir pollutionoInhalation of asbestos fibersoExposure to radon, a radioactive substance formed by breaking down uraniumoInhalation of marijuana fumes by smokingoExposure of the chest area to radiation therapy during cancer treatmentoHereditary reasonsoPresence of arsenic in drinking wateroDiet with low fruit and vegetable content (this increases the risk of lung cancer in smokers)A combination of exposure to tobacco along with any of these causes greatly increases thechances of a person contracting lung cancer.Lung Cancer Symptoms
The following are some of the common symptoms of lung cancer. They do not usually manifest inthe early stages. Even if they do, they are usually mistaken for some other ailment. Thesesymptoms are:oPersistent coughingoReddish or muddy brown spitoLoss of breathoLoss of appetiteoPersistent or repetitive infections of the bronchial tractoHoarseness of voiceoRenewed wheezingIn its later advanced stages, when the lung cancer is said to be in metastasis, the symptoms are:oNumbness in the arms or legsoA jaundiced appearanceoTumorous growths near the skin surfaceoSeizuresoBone painoDizzinessLung Cancer Detection and DiagnosisIt is very rare to be able to detect lung cancer in its early stages. There are no specific symptomsof early stages of lung cancer. This is one of the reasons why lung cancer is usually detected in itslater stages.The use of a proper screening technique would greatly increase the chances of early lung cancerdetection. However, there is no such proper and totally effective screening technique yet.Research is on to see if one can be formulated soon. As of now, a new technique called spiral CTseems to be the best option for early detection.Once lung cancer is detected, the next step is to determine the stage it is in. This is done using theAJCC system. Roman numerals are used to mark the different stages of lung cancer, numeralsfrom 0 to IV. Sometimes the stages are further divided into substages, using denotations A and B.The general rule of thumb is that the lower the denomination, the less serious the condition.
Lung Cancer TreatmentLung cancer treatment options are usually the same as prostate cancer treatment options or coloncancer treatment options. What I mean is that all forms of cancer have the same treatmentoptions. However, lung cancer tests may be different from colon cancer tests. The standardtreatment options for lung cancer are:oSurgeryoRadiation TherapyoChemotherapyWhat matters is the combination of methods being used. The more serious the cancer, the morechances that different treatment options will be used in tandem, or one after the other.Referencesohttp://www.aacr.orgohttp://www.cancer.gov/cancertopics/types/colon-and-rectalohttp://www.cancerbackup.org.uk/Cancertype/Lung/General/Typesoflungcancerohttp://www.cancer.orgohttp://www.lungcanceronline.orgThe writer does freelance writing work.
