The incidence of lung cancer is increasing across the country. Lung cancer is the leading cause of death among cancer patients. However, if this disease is diagnosed and treated early, the patient has a better chance of recovery. Six out of ten people with lung cancer survive more than five years with treatment. If the disease is not diagnosed early, this rate drops to less than one in ten. Therefore, periodic health check-ups are very important for lung cancer patients.
According to the World Health Organization, lung cancer is the leading cause of cancer-related deaths worldwide, with smokers being at the highest risk. However, lung cancer is also increasing among non-smokers, a condition known in medical terms as non-passive smoking. The lungs are part of the respiratory system and are located on each side of the chest. These two spongy organs help to inhale oxygen and release carbon dioxide. When cancer cells form in this organ and then spread to other parts of the body, it is called lung cancer. Lung cancer is mainly caused by smoking. 60-70 percent of patients who smoke develop lung cancer.
