Lung cancer tends to only show signs and symptoms in advanced stages. These include:
Smoking is one of the key causes of lung cancer, due to cigarette smoke containing numerous carcinogens that affect your lung tissue with prolonged exposure. Over time, the cells that line your lungs are increasingly damaged, causing them to act abnormally and give rise to cancer. For non-smokers, secondhand exposure to smoke as well as carcinogens such as asbestos and diesel exhaust can lead to the development of lung cancer as well. Doctors also theorise that inherited faulty DNA repair mechanisms can also lead to some NSCLCs.
Risk factors of lung cancer include:
The best way to avoid lung cancer is to stop smoking or avoid starting, as well as reduce exposure to secondhand smoke from others. In addition, do take precautions at work and wear protective gear to avoid unnecessary exposure to workplace carcinogens. Other ways to prevent it include eating a healthy and balanced diet, as well as including regular exercise into your lifestyle.

EBRT is a commonly utilised radiation treatment to kill cancer cells that are still localised to a region of the lung and within its lymph nodes.
Chemotherapy plays a key role in treating SCLCs, and is frequently used in combination with radiation treatment for later stages of lung cancer.
Surgery is more frequently used to treat earlier stages of lung cancer, such as stage I and II.
Targeted drug treatment helps treat patients whose cancer cells have certain abnormal genetic mutations that render them vulnerable.
