Lungs cancer: Symptoms, Cause and Screening


Lung cancer is a type of cancer that starts in the lungs and spreads throughout the body. When you breathe in and out, your lungs are two spongy organs in your chest that take in oxygen and exhale carbon dioxide. Lung cancer is more common in smokers, although it can also strike nonsmokers. The risk of lung cancer increases when you smoke for longer periods of time and consume more cigarettes.


In the early stages of lung cancer, there are often no signs or symptoms. Lung cancer signs and symptoms usually appear after the disease has progressed

  • Coughing up blood, even if it’s only a little bit
  • Difficulties breathing
  • Discomfort in the chest
  • Hoarseness
  • Weight loss that is uncomplicated
  • Aches and pains in the bones
  • Headache

When should you consult a doctor?

If you have any persistent signs or symptoms that concern you, schedule an appointment with your doctor. Make an appointment with your doctor if you have not been able to quit smoking.


Lung cancer is the most common cause of death in both smokers and those who are exposed to secondhand smoking. People who have never smoked or been exposed to secondhand smoke for a long time can develop lung cancer. Lung cancer can have an etiology that is unclear in some cases.

Lung cancer is commonly caused by smoking.

Smoking, according to doctors, promotes lung cancer by harming the cells that lining the lungs. Lung tissue changes quickly when you inhale cigarette smoke, which is high in toxins.

Lung cancer has several different types.

On the basis of the appearance of cancer cells under a microscope, doctors divide lung cancer into two basic kinds. Non-small cell lung cancer and small cell lung cancer are the two forms of lung cancer.

Lung Cancer with Small Cells

Cancer of the lungs with a modest number of cells. Small cell lung cancer is rarer than non-small cell lung cancer, and it primarily affects heavy smokers.

Lung Cancer (Non-Small Cell)

Non-small cell lung cancer is a broad phrase that refers to a variety of lung malignancies. This type of lung cancers includes squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.

Factors at Risk

Stopping smoking, for example, is a risk factor that can be lowered. Other factors, such as your family history, are beyond your control.

Lung cancer can be caused by a number of things, including:


The number of cigarettes you smoke each day and the number of years you’ve smoked raise your risk of lung cancer. Quitting smoking at any age significantly reduces your risk of lung cancer.

Exposure to secondhand smoke

Secondhand smoke can increase your risk of lung cancer even if you don’t smoke.

In the past, radiation therapy was used.

You may be at a higher risk of developing  cancer if you have had chest radiation therapy for another type of cancer.

Radon Gas Inhalation

Radon poisoning is caused by inhaling radon gas. The natural breakdown of uranium in soil, rock, and water produces radon, which eventually enters your lungs.


Lung cancer complications include:

Shortness of breath

Patients with lung cancer may experience this if the malignancy has progressed to the point where it has clogged the major airways.

Blood was coughed up.

Airway bleeding caused by lung cancer can result in blood in your cough (hemoptysis). The bleeding can be rather severe at times. Medicines are available to aid in the control of bleeding.


Pain can be caused by advanced lung cancer that has progressed to the lungs’ lining or to another part of the body, such as a bone.

Lung Cancer Screening

Screening for lungs cancer is a method of diagnosing lung cancer in persons who are otherwise healthy but at high risk of developing the disease. Lungs cancer screening is advised for elderly persons who have smoked for a long time but have no symptoms or signs of lung cancer. Lungs cancer is more likely to be successfully treated if it is found early.

Lung cancer screening Singapore tries to detect lung cancer at an early stage when it is more likely to be cured. By the time signs and symptoms of lung cancer show, it is usually too late for curative therapy. Lung cancer screening, according to research, reduces the risk of death from the condition.

In Singapore, where can I find a lung cancer specialist?
