Overview of Lung Cancer screening Singapore


The lung cancer screening is a procedure which is used to identify whether there is lung cancer among healthy individuals with a high risk of developing lung cancer. The screening for lung cancer is suggested for those who smoke for a long time and do not have indications or signs for lung cancer.

Doctors make use of a low-dose, computed tomography (LDCT) scan of the lungs to search for signs of lung cancer. If cancer of the lung is discovered in its early stages it’s more likely be treated and cured.

Discuss the risks and benefits for lung cancer detection with LDCT with your physician. Working together, you will be able to decide if the screening is suitable for you.

The reason

The purpose of screening for lung cancer is to find out if you have lung cancer at an young stage — at which point it is more likely to be treated. At the point that the signs and symptoms of lung cancer appear the cancer is generally too advanced to be treated. Research has shown that screening for lung cancer lowers the chance of dying from lung cancer.

Who should screen

Screening for lung cancer is typically reserved for those who are at the highest risk of developing lung cancer, which includes:

Senior adults who are currently or ex-smokers. The screening for lung cancer is typically available to smokers and former smokers aged 50 or older.

Smokers who have been smoking heavily for a long time. It is possible to be able to consider a lung cancer screening test when you have a record of smoking cigarettes for more than 20 years in a pack. Pack years are determined by multiplying by the number of cigarettes you smoked in a day by the number of years in which you consumed cigarettes.


A person who has 20 pack and years of history could have smoked one pack of every day over 20 years or two packs per day for 10 years, or half of a pack daily for forty years. Although your smoking habits may have changed over time the information you have about your smoking history could serve as a basis for determining if lung cancer screening Singapore is beneficial to you.

Smokers who used to smoke regularly, but have since stopped. If you were a frequent smoking smoker over a lengthy period of time and have quit smoking within the fifteen years prior to that it is possible to consider smoking-related testing.

If you suffer from significant health issues then you are less likely to get Lung cancer screening as you are more likely to suffer from complications from the follow-up tests. Because of this, Lung Cancer screening is provided to people generally healthy.

Screening is usually not advised for patients with low lung function or grave conditions that make surgery challenging. It could be the case for people who require continuous supplemental oxygen or have experienced an unproven weight loss in the last year, or have coughed up blood recently, or been through the chest CT scan in the past year.

Patients with a background for lung cancer. If you’ve been treated for lung cancer for more than five years back, you should think about screening for lung cancer.

Other risk factors can increase the risk in the case of lung cancer. The risks for developing lung cancer might include people with chronic obstructive lung disease (COPD) or those with an ancestral background of cancer, and individuals who are exposed to asbestos in their work.

How long do you have to keep screening?

The medical community isn’t all in agreement on the time at which you can think about stopping screening for lung cancer. In general, you should continue with annual screening for lung cancer until a stage that you’re no longer likely to gain from the screening, for instance, if you develop other serious health issues which could make you fragile to undergo treatment for lung cancer.


Lung Cancer screening carries several risks, such as:

The exposure to a lower dose of radiation. What amount being exposed to when you undergo an LDCT is significantly lower than the standard CT scan. It’s about 50% of the radiation you’re exposed to in the natural environment over the course of one year.

Follow-up tests should be conducted. If your scan reveals an unusual spot on one of your lungs, you could require additional scans that expose you to more radiation or more invasive tests, like a biopsy that carry serious risk. If the additional tests prove that you do not have Lung cancer then you could be exposed to severe risk that you could have avoided if not take a screening.

Cancer that’s too advanced for treatment. Lung cancers that are advanced, like ones that have spread might not be able to respond to treatment, which is why identifying the cancers in an exam for lung cancer could not prolong or improve your lifespan.

A cancer diagnosis that isn’t likely to cause harm to you. Certain lung cancers progress slowly, and they don’t necessarily cause any symptoms or harm. It’s not easy to tell which cancers are unlikely to cause harm and which ones need to be removed as quickly as possible to avoid injury. In the event that you’ve been diagnosed with cancer of lung, your physician will most likely suggest treatment. The treatment for tumors which could remain small and untreated for throughout your life could not be beneficial to you, and could be unneeded.

Cancers that are not detected. There is a chance that Lung cancer could be overlooked or hidden during the Lung cancer screening test. In this case your results could suggest that you do not have lung cancer even though you actually have it.

The scan can reveal other health issues. Smokers for long periods have an increased risk of developing other ailments, including heart and lung diseases which can be identified on the lung CT scan. If your physician discovers a different health problem, you might undergo further tests, and perhaps, more invasive treatments that might not have been considered in the absence of the screening for lung cancer.

How to make?

In order to get ready for an LDCT scan you might need to:

Tell your lung surgeon Singapore if suffer from a respiratory tract illness. If you are currently showing symptoms or signs of an infection of the respiratory tract or if you have recently recuperated from an infection your doctor might suggest delay your test until one month after the symptoms have gone away. The respiratory tract infection can cause changes on CT scans which could require further scans or tests to determine. The additional tests could avoid them by waiting until the condition to heal.

Get rid of any metals that you’re wearing. Metals can affect the image, and you could be asked to take off any metal you may be wearing, like glasses, jewelry, aids, or dentures.
