How smoking can cause lung cancer ? Symptoms - Diagnose - Biopsy Results

Lung cancer is one of the main causes of human death , both men and women. Although this condition is rare, but the danger remains will always be threatened . Before many brands of cigarettes were scattered on the earth , will the incidence of lung cancer is quite rare and infrequent . Today, smoking has caused nearly 9 out of 10 deaths from lung cancer . While pollution , radon gas , and other chemical exposure only plays a smaller role . A number of drugs have been developed to provide new hope for those who are diagnosed with lung cancer .

How smoking can cause lung cancer ?Cigarettes are not only packed with cancer-causing chemicals , but can also attack the natural defense system of the lung known as cilia . Airway cilia are coated with fine hairs . These feathers play a role in protecting the lungs by sweeping toxins , bacteria , and viruses . Tobacco smoke can paralyze cilia , making it unable to do his job well . This will lead to accumulation of carcinogens ( cancer causing substances ) in the lungs .

Symptoms of Lung CancerLung cancer starts in stealth mode . Usually there are no symptoms or warning signs in the early stages . Because of that , the symptoms of lung cancer are usually not specific , but the often encountered are as follows :1 . A cough that will not go away2 . Chest pain , especially when breathing deeply3 . shortness of breath4 . Coughing up phlegm with blood5 . fatigue 

Diagnose Lung CancerIn most cases , lung cancer is not suspected to cause symptoms such as chronic cough or wheezing ( shortness of breath ) . At that time , the doctor will most likely perform the chest X-ray . The doctor usually will ask the patient to test sputum ( sputum ) . If any of these tests indicate the presence of cancer , the patient will likely undergo a biopsy ( removal of tissue for the body for the purpose of laboratory examination ) . 

Lung Biopsy Results

If a tumor is suspected to have been seen in the X - ray ( X-ray ) , or cancer cells appear in the sputum test , the biopsy is used to diagnose the disease . The pathologist examines a small sample that has been suspected as a tumor through a microscope . By examining these samples , the pathologist can determine whether the tumor is lung cancer or not .Types of Lung CancerThere are two main types of lung cancer are distinguished from forms of cancer cells are examined under a microscope , namely small - cell lung carcinoma ( SCLC ) and non-small - cell lung carcinoma ( NSCLC ) . Carcinoma small cell lung ( SCLC ) is the most aggressive and can spread quickly to other parts of the body . It is strongly associated with smoking , and rarely occurs in nonsmokers . While lung carcinoma non-small cell ( NSCLC ) are known to be slow its spread and common, about 90 percent of all lung cancer incidence .Stage Lung Cancer

Stage or level is used to describe how far a patient's cancer has spread . There are different systems for two main types of lung cancer . Lung cancer small cell ( SCLC ) is divided into two levels namely : " Limited ( Limited ) " , meaning the cancer is limited to one lung and perhaps close to the lymph nodes . The second is " Wide ( Extensive ) " , meaning the cancer had spread to the other lung or outside it . As for lung cancer non-small cell given the extent ( stage ) of one to four , depending on how far it has spread .Figures Survival for Lung Cancer Patients

The survival rate of lung cancer diagnosis depends on the stage . The possibility of patients live at least five years after diagnosis ranged from 1 % to 49 % for patients with lung cancer non-small cell . However, the treatment of this cancer has been well developed over the last decade , so that prospects for the future will also be better . 

Treating Early Stage Lung CancerWhen non-small cell lung cancer was detected before it spread to more than one lung , usually surgery can be a cure . Surgeons can remove part of the lung containing the tumor , or if necessary , entirely . Some patients given radiation therapy and / or chemotherapy after surgery to kill any cancer cells remaining . The operation is usually not an option for cancer patients with small cell lung because it usually has spread at the time of diagnosis .Treating Lung Cancer AdvancedWhen lung cancer is too difficult to be cured , treatment can still help patients live longer and maintain a better quality of life . Radiation therapy and chemotherapy can shrink tumors and help control symptoms such as bone pain or blockage of the airways. Chemotherapy is usually the main treatment for lung cancer is small cell .

Life After Diagnosis
Diagnosed with lung cancer is very surprising , and if it is associated with smoking , there must be a feeling of guilt as well . But now is not the time to blame yourself . Instead , experts advise to look ahead . Not too late to make healthy lifestyle changes . There is evidence that patients who quit smoking after finding out they had cancer lung changes better condition than those who continued to smoke .Lung Cancer and Passive Smokers

Lung cancer is not only caused by smoking alone . Frequent inhalation of cigarette smoke in the home or public places can also be affected. Passive smoking can also risk developing lung cancer by 30 percent compared with those who rarely or exposure to cigarette smoke inhalation .Lung Cancer and Occupation Specific

Certain jobs may also increase the risk of lung cancer both in smokers and non . The people who work daily with uranium , arsenic , and other industrial chemicals must confine itself against exposure to these materials . Asbestos is also an industrial material that can cause lung cancer .Lung Cancer and Air Pollution

Air pollution can also contribute to the increased risk of lung cancer . Experts believe that air pollution from motor vehicles , factories , and power plants can affect the risk of lung cancer in a way that is almost the same like cigarette smoke . Around the world , air pollution is estimated to have caused approximately 5 % of deaths from lung cancer .Other risk factors

Other factors that may influence the occurrence of lung cancer is a family history who have had lung cancer . In addition , the high arsenic drinking water can also cause risk of lung cancer .Prevention of Lung Cancer

Lung cancer may be one of the most deadly forms of cancer , but also one of the most preventable . The trick is to not smoke . And if you are a smoker , then quit smoking immediately . Within five years of quitting , the risk of dying from lung cancer will drop to half of those who smoke as much as a pack a day . And 10 years after quitting , the risk of dying from lung cancer will be almost the same as those who had never smoked
