Lung Cancer

November 17, 2022

Lung cancer is the abnormal growth of tissues in the lungs. This type of cancer starts in the lungs, and develops due to the abnormal growth can pass to the other parts of the body.


So, what exactly are the risk factors for lung cancer? 



Smoking has been recognised as an important risk factor of lung cancer. The greater the amount of smoking, the longer the smoking period, the earlier the age of starting smoking, the higher the lung cancer mortality rate. In addition to active smoking, inhaling second-hand and third-hand smoke can also lead to lung cancer.

Kitchen fumes 

Kitchen fumes are 1.harmful gases generated during cooking. Studies have uncovered reasons such as overcooking, types of food cooked, and fumes from cooking oil. To reduce the toxic fumes, the kitchen must be kept ventilated, and a fume extractor can be used. 


Occupational hazards

Some work environments expose individuals to carcinogens – including asbestos, inorganic arsenic compounds, dichloromethyl ether, soot, and tar –  that can lead to lung cancer in the long term. 


Renovation-related pollution

Homes that are renovated, or newly renovated houses can emit a variety of carcinogens. Research results released by the World Health Organization show that indoor radon has become the second largest cause of lung cancer after smoking.


Many people are diagnosed with lung cancer at an advanced stage. This is mainly because symptoms of lung cancer are too common, and can often be overlooked as minor diseases. There are, however, some symptoms that can raise alerts which you should get checked as soon as you can. 

  • Chest pain
  • Coughing up blood 
  • Hoarse voice
  • Chest tightness and shortness of breath
  • A new cough that that doesn’t go away
  • Losing weight without trying
  • Bone pain 


As these symptoms can also be related to other health issues, should you experience any of the warning signs, do seek professional advice as soon as you can.
