Cigarettes Can Damage Genes In Minute Counts

Info Update,Jakarta: It's a warning for smokers. Your Genes can be damaged in just minutes when smoked cigarettes. In fact, cigarettes can also be a serious threat to your cancer. Thus the results of the study a number of scientists in the United States study published in the journal Chemical Research in Toxicology, recently.

Researchers say the effects of smoking for health very quickly. Similar to inject something directly substances into the bloodstream. The study was conducted to track how the substances in tobacco can cause DNA damage.

DNA or deoxyribonucleic acid (deoxyribonucleic acid) is a type of nucleic acid biomolecules that are categorized as major constituent of dry weight of each organism. Inside the cell, DNA is generally located in the nucleus of cells.

Broadly speaking, the role of DNA in a cell is a genetic material. That is, DNA stores the blueprint for all the activities of the cell. This applies generally to any organism.

By using 12 smokers as volunteers, scientists trace pollutants called PAHs, or polycyclic aromatic hydrocarbons. This is contained in tobacco smoke and can also be found in power stations are coal-powered and in baked goods.

They follow the development of one particular type - phenanthrene, which is found in cigarette smoke - through blood and watch it form a toxic substance known untukmelacak DNA, causing mutations that can cause cancer, the study said.

"Smokers develop maximum levels of substances that in a time frame that even surprised the researchers, that is just within 15-30 minutes after the volunteers to end smoking," the study said.

These results are very important because PAH diol epoxides react with DNA, promote mutations, and is regarded as the leading cause of cancer of many PAHs in cigarette smoke.

Scientist who led the research said Stephen Hecht, a study was unique because it examines the impact of people inhale cigarette smoke, without interference from other sources such as pollution or harmful foods with poor nutrition. "The results reported here should be a clear warning for those considering to start smoking cigarettes," said Hecth.

Lung cancer killed some 3,000 people around the world every day. About 90 percent of the deaths were caused by cigarette smoke.

Lung cancer is one cancer that quite often occur. Among smokers in particular, malignant disease has become a major threat and has become a close friend.

Lung cancer is characterized by the presence of abnormal tissue growth in the lungs, which if left unchecked can spread to other organs, both close to the lungs and far such as bone, liver, or brain.

In the early stages, lung cancer is difficult to identify. If the size is still small, or roughly less than three centimeters. The disease generally does not cause significant complaints. When the size of the cancer is larger and spread to various other organs, only then will lead to complaints, such as coughing up coughing accompanied by blood. Not infrequently, resulting shortness of breath.

Shortness of breath usually arises gradually and increasingly severe. Shortness of breath occurs as a result of an accumulation of fluid in the pleural cavity (the cavity between the lung lining and chest wall). The volume of the liquid itself can achieve a liter more.

Imagine, a liquid which would have caused so much trouble in humans to draw and exhale.

Lung cancer can also be characterized by several other symptoms such as appetite disappeared accompanied by drastic weight loss, body weakness (malaise), and is easy to feel tired. Sometimes swelling also occurs in the face, neck, and chest. So let's quit smoking from now.
