Causes of Lung Cancer | Asbestos Cancer

Causes of Lung Cancer - Smoking is a major cause of about 90% of cases of lung cancer in men and about 70% in women. The more cigarettes smoked, the greater the risk for lung cancer.

Only a small proportion of lung cancer (about 10% -15% in men and 5% in women) caused by or inhaled substances encountered at work. Working with asbestos, radiation, arsenic, chromate, nickel, chloromethyl ethers, mustard gas and coke oven emissions can cause lung cancer, although usually only occurs in workers who also smoked.

The role of air pollution as a cause of lung cancer is still unclear.
Some cases occur because of exposure by radon gas in the household.

Sometimes, lung cancer (particularly adenocarcinoma and alveolar cell carcinoma) occurred in people who already have lung scarring due to other lung diseases, such as tuberculosis and fibrosis.

Lung Cancer Due to Smoking

Lung Cancer Due to Smoking - The cells lining the mouth reflect the molecular damage caused by cigarettes in the lining of the lungs, U.S. researchers reported.

Examination of oral tissue lining the mouth to measure the molecular changes that cause lung cancer can save patients and people at risk of developing lung cancer from uncomfortable procedures used now, said the team of researchers.

Smoking is the leading cause of lung cancer, but only about 10% of smokers who attack the disease. The disease causes few symptoms until the developing world, which means patients are rarely diagnosed or treated until it is too late to treat.

Mao's team, wanted to find a way to monitor patients who use one drug, COX-2 inhibitor celecoxib, sold by Pfizer (PFE.N) under the name Celebrex, hoping to prevent lung cancer.

They studied two genes, known to help prevent cancer development, p16 and FHIT. There are fundamental damage (in both genes) long before the cancer struck, "said Mao.

When speaking at the meeting of the American Association for Research Center in San Diego, they said they were seeking special damages in both of these genes in lung samples and mouth of 125 older smokers.

"We talked about just checking in to obtain the same information that we get from brushing lungs obtained through bronchoscopy,"

said study presenter Dr. Manisha Bhutani who worked with Mao.

The team examined the oral tissues and the lung lining called the epithelium, in 125 chronic smokers enrolled in the study. The status of two important genes that suppress tumors analyzed. Gene, p16 and FHIT, are known to damage very early in the process of cancer development.

Causes and Prevention of Lung Cancer

Cause of lung cancer: Cancer has become a deadly disease, even lung cancer is the first killer than any other cancer. Tumor cells or cancer that grows in the lung experienced by patients with lung cancer. Cancer can grow in this tissue and can spread to other parts.

The main cause of lung cancer is cigarette smoke contains many toxic substances and inhaled into the lungs and has been accumulating for decades causing mutations in the airway cells and causes cancer cells.

Another cause is the radioactive radiation, toxic chemicals, stress or heredity.

Lung cancer symptoms: cough, chest pain, shortness of breath, coughing up blood, tiredness and weight loss. But as in other cancer types, symptoms are generally only visible when the cancer has grown large or has spread.

Prevention of lung cancer: Avoiding cigarettes and cigarette smoke are also more nutritious foods that contain lots of antioxidants to prevent cancer cells.

Because the disease in the lungs primarily caused by cigarette smoke, then you should immediately stop this habit, and do not try to start it for those of you who have never smoked. Avoid also to be passive smokers are even more dangerous than active smokers. Love the lung, avoid the lung disease, and you can breathe more easily.
