|Lung Cancer is a Common Disease|
The lung is an important organ in the body. Lungs allow humans to breathe in oxygen and breathe out carbon dioxide. Sometimes lungs develop diseases such as asthma, emphysema and cancer.
Symptoms of Lung Cancer
Cancer of the lungs often does not have symptoms until the disease has progressed. Symptoms of this disease include: trouble breathing, shortness of breath, coughing up blood, a cough that will not go away and a hoarse voice. A person who has symptoms of lung cancer should visit a doctor. Symptoms of lung cancer are also symptoms of other various diseases or illness; therefore, a person with symptoms should visit a doctor.
Causes of Cancer of the Lungs
Many things cause cancer to develop in the lungs. Smoking cigarettes is a very common cause of developing this disease in the lungs. Tobacco smoke causes harm to cells in the lung. Tobacco smoke often causes a person to develop cancer. Individuals who are around tobacco smoke but do not smoke are also at a risk for developing cancer.
Air pollution, radon, asbestos, arsenic and other chemicals also cause cancer of the lungs. Family history also plays a role in developing this disease. A person who has a family history of lung cancer and smokes cigarettes is at an even greater risk for developing this disease. The more risks a person has for developing cancer of the lungs the more likely the person is to develop the disease.
