Smoking and Increased Health Risks

Smoking increases the health risks & causes heart diseases, mouth cancer & lung cancer. When you smoke, the smoke damages the cell lining the coronary artery. Coronary artery is the major blood vessel that supply your heart with blood, oxygen and nutrients. When plaque builds up in, it narrows your coronary arteries, decreasing blood flow to your heart. Eventually, the decreased blood flow may cause chest pain (angina), shortness of breath, heart attack & heart failure. Furthermore, doctors believe, smoking causes lung cancer by damaging the cells that line the lungs. When you inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), changes in the lung tissue begin almost immediately. At first your body may be able to repair this damage. But with each repeated exposure, normal cells that line your lungs are increasingly damaged. Over time, the damage causes cells to act abnormally and eventually cancer may develop. In addition to that, some of the chemicals contained in tobacco smoke cause, initiate or promote mouth cancer. Tobacco in cigarette exposes the mouth to the carcinogenic chemicals during inhalation while smoking. These chemicals cause genetic changes in cells of the mouth cavity which can lead to the development of oral cancer. In a nutshell, we should must keep ourselves away from smoking for protecting ourselves from fatal diseases & to have a safe & sound health.
