Lung Cancer starts in the cells that line the bronchi and parts of the lung such as the bronchioles or alveoli.
There are two main types of primary Lung Cancer:
The lungs form part of our respiratory (breathing) system, which includes:
The trachea, bronchi and lungs. As we breathe in, air passes from our nose or mouth, through the trachea, bronchi and bronchioles, before it reaches tiny air sacs called alveoli – this is where oxygen from the air passes into the bloodstream.
The most common symptoms of Lung Cancer are:
You should see your doctor if you experience any of these symptoms. However, it is important to remember that these symptoms are common in people who do not have lung cancer as well; they may also be caused by other conditions.
Cigarette smoking is the most common cause of lung cancer. In India, it is responsible for 70% of cases in men and 30% of cases in women (IPSOS data). The number of years that a person has been a smoker is more important than the number of cigarettes smoked per day; therefore, giving up smoking at any age can reduce the risk of developing lung cancer more than cutting down on the number of cigarettes smoked per day.
Passive smoking, also referred to as ‘second-hand smoke’ or ‘environmental tobacco smoke’, can be hazardous to adults and children. Secondhand smoke contains the same toxic substances as directly inhaled smoke. Secondhand smoke is an important cause of death from both lung cancer and heart disease.
Radon in homes and workplaces is recognized as an important risk factor for lung cancer. Radon is a radioactive gas that occurs naturally in the ground. Radon leaks out of the ground and into houses or buildings, where it is then inhaled. You cannot see or smell radon.
Some people are more likely to develop Lung Cancer based on their genetic makeup. Having a family history of Lung Cancer, or other types of cancer, increases the risk of developing lung cancer. In people who are genetically predisposed to Lung Cancer, smoking further increases the risk.
Asbestos and Arsenic exposure increases risk factors for the development of Lung cancer. It has also been suggested that indoor air pollution from the use of coal-fuelled stoves may be a factor.
Don’t start smoking if you haven’t already. Talk to your peers about smoking being the major cause of lung cancer. Begin conversations about the dangers of smoking with your loved ones.
If you’ve cultivated a habit of smoking, then now is the time to reduce. Quitting cigarettes lowers the risk of lung cancer, even if you've smoked for years. Talk to your doctor about strategies and stop-smoking aids that can help you quit. Nicotine replacement products, medications, and support groups are a good way to start.
If you spend time with a smoker, urge him or her to quit. At the very least, ask him or her not to smoke around you. Avoid areas where people smoke, such as bars and restaurants, and seek out smoke-free places/points for healthier lungs.
Exposure to toxic chemicals at work can also add to the risk of Lung Cancer. Use safety equipment such as a face mask for protection in case the workspace has chemicals involved. Furthermore, the risk of lung damage from workplace carcinogens increases if you smoke.
If exercising isn’t a part of your everyday schedule, then start out slowly. Try staying active most days of the week.
