The result of the examination
There are three possible results: Negative, positive and doubtful.
What is a negative screening result
This result means that no indications of lung cancer were found on the CT scan. This is the most commonly encountered result. Approximately 82 in every 100 people will receive a negative test result. A negative result for the first scan means that you will be invited for a CT scan again until you have completed all CT scans. The study group to which you have been assigned will determine when your next CT scan takes place.
What is a positive screening result
The CT scan shows abnormalities in the lung that point to lung cancer. Further examination by the lung specialist is needed to determine whether it actually involves lung cancer. The size and location of the deviation will determine which examinations are necessary. The lung specialist will discuss this with you when you are referred.
Approximately 8 in every 100 people receive a positive result. But not all people actually have lung cancer. Of every 2 people who are referred to the lung specialist, 1 person will effectively have lung cancer. The lung specialist will mention the treatment options if lung cancer is discovered.
What is a doubtful screening result
The CT scan showed a few minor abnormalities in the lungs, which do not immediately point to lung cancer but there are still doubts. This is often inflammation or scarring. To be on the safe side, an extra CT scan will be carried out after approximately 3 months. Approximately 10 in every 100 participants undergo a repeat CT scan. This is not the same as a referral to the lung specialist. A repeat CT scan makes it possible to compare the two CT scans with each other. This makes it possible to measure the speed with which the spot has grown.
Minor spots that have not, or have barely, grown require no further treatment. This will lead to a negative result. Spots that grow quickly are more suspicious. They will result in a positive result
