Asthma Lung Cancer

According to current researches, scientists have proved that the asthma patients are at high risk for developing lung cancer regardless of other risk factors of lung cancer like smoking or even secondary smoking. We all know that smoking is the major cause of lung cancer and the occurrence of disease depends on rate of smoking and its duration, if these smokers are asthmatic or suffers from emphysema chronic bronchitis the risk of developing asthma is even more. No other lung disease other than these has been found to be associated in developing lung cancer.

Emphysema is actually a chronic disease of the lower reparatory track it is a chronic obstructive pulmonary disease. The major symptom is difficulty in breathing. Smoking is the major cause for emphysema. Emphysema also gets induced due to the frequent exposure to other air pollutants like dust, fumes etc. Frequent and long term smoking or the exposure to various irritants may lead to destruction of membranes between the alveoli and also reduces the elasticity of the bronchioles and alveoli which makes breathing more difficult. The chronic respiratory disease may lead to lung cancer. Thus quitting smoking and avoiding exposure to irritants helps in reducing the chance of developing emphysema and thus the lung cancer.

Bronchitis is the inflammation of respiratory airway caused due to exposure to various irritants like smoke, dust, fumes etc. It is actually the disease of upper airways especially the bronchial tubes and the successive bronchi. The major symptom of bronchitis is severe coughing along with mucus production. These mucus acts as a barrier   in the bronchial tubes for the smooth flow of air during respiration.  The patient often feels tightness of chest and difficulty in breathing. There are two kinds of bronchitis acute bronchitis and chronic bronchitis.

The acute bronchitis can be cured easily on the other hand chronic bronchitis lasts for 2 - 3 months. Emphysema and chronic bronchitis together forms “Chronis Obstructive Pulmonary Disease” or COPD. Like emphysema, smoking is the most prominent cause of bronchitis. This irritant triggers the production of mucus and finally worsens the symptoms. According to some scientists the chronic bronchitis may lead to lung cancer in some patients but majority of the scientists disagree with this and they don’t believe that the chronic bronchitis may lead to lung cancer.

Since smoking is the major cause of emphysema, bronchitis and asthma there are chances for these patients getting infected with lung cancer. Lung cancer is the major cause of cancer death. In lung cancer the normal cells gets transformed to cancerous cell. The cancerous cells under go rapid proliferation in an uncontrollable manner and these cancerous cells utilize the oxygen, nutrients and space meant for the normal cell and thus the normal cells growth gets suppressed. The pathological test of tissue biopsy from lungs helps in the proper diagnosis of lung cancer. The major external symptom is severe coughing and chest pain. Smoking is the major factor that links asthma with the lung cancer. Studies have shown that females are more prone to lung cancer than males.
