Lungs Cancer is a disease of uncontrolled cell division in the tissues of the lungs. The cells continue to divide without any control and form tumours. The cellular growth may also invade adjacent tissues beyond the lungs. The most common symptoms are shortness of breath, coughing (including coughing up blood) and weight loss.
The lung is the most common cause of cancer-related deaths and is responsible for more than 1.3 million deaths worldwide annually.
Lungs Cancer Causes and Effects
The main causes of any lungs cancer include carcinogens ( such as those in cigarette smoke) ionizing radiation and viral infection. Smoking is the main cause of lung cancer. The risk of lung cancer is significantly lower in the non-smokers. Cigarette smoke contains over the 50 known carcinogens.
If a person stops smoking, the chance to develop cancer disease as damage to the lungs is repaired and contaminant particles are gradually removed.
Eliminating tobacco smoking is a primary goal in the prevention of lungs cancer. The World Health Organization has called the governments to stop tobacco advertising to prevent young people from taking up smoking.
