The largest single cause of cancer deaths is lung cancer. It is a disease characterized by abnormality in the cell of the lungs. The body normally maintains a system of checks and balances on cell growth. Disturbance on this system results in an uncontrolled division and propagation of cells. This will form a mass known as tumor.
Tumor has 2 types, benign and malignant. Cancer is a malignant tumor. It grows assertively and attacks other tissues of the body. This will allow tumor cells to enter into the bloodstream or lymphatic system then to other parts of the body. This process is called metastasis. The lung is a common site of this process.
One on the common leading risk factor for lung cancer is smoking. Based on the lung cancer facts, more than 8 out of 10 cases of lung cancer are caused by tobacco smoke. A person who smokes longer and smoked more packs a day has the greatest risk of having lung cancer. The lung tissue will slowly return to normal if a person stops smoking before developing cancer.
Passive smoking or breathing second-hand smoke also has high risk of lung cancer. It is the third leading cause of preventable death. Non-smokers exposed to second-hand smoke raise their risk of developing lung cancer by 20 to 30 percent.
Air pollution is also a risk factor based of the lung cancer facts. Up to 1% of lung cancer deaths are caused by breathing polluted air. Prolonged exposure to highly polluted air can also carry the risk of getting lung cancer the same to that of passive smoking.
Asbestos is also a risk factor. Asbestos fibers are silicate fibers that can destroy lung tissue. People can be exposed to asbestos fibers in workplace. Asbestos was used as thermal or acoustic insulation. Other risk factors are diet, personal and family history and radiation therapy to the lung.
Once cancer has been diagnosed, radiation, different chemotherapies and surgery are treatment choices. According to facts about lung cancer, the survival rates have increased because of the development in radiation and chemotherapy treatment.
The key to a successful therapy is early detection. You should be evaluated by a physician immediately if you have history of chronic coughing, coughing up blood, shortness of breath, hoarseness and wheezing, chest paint, bronchitis or pneumonia, weight loss or loss of appetite, swelling of the neck and face, or fatigue.
Lung cancer facts say the best way to prevent lung cancer is to avoid smoking. Not smoking or stop smoking is the best way to avoid death caused by lung cancer. It is important also to avoid passive smoke, asbestos, radon, and pollution. They can also add to the risk of developing lung cancer. You should also need to control other lung diseases like tuberculosis. In some studies, it is found out that a lung cancer can also be developed in scarred areas of the lung. Lastly, eating healthy foods and good diet with plenty of fruits and vegetables can also be helpful in preventing lung cancer.
