Other types of cancer screening
There is ongoing research also on other cancer screenings. So far no sufficient scientific evidence has been available to initiate them.
Finland has participated in a European joint study that found that PSA-based screening reduces the deaths from prostate cancer by one-fifth (1.). Despite this, prostate screening is still not recommended in any European country due to the disadvantages it has caused, including considerable overdiagnosis and overtreatment.
The screening of smokers using low dose computed tomography has cut lung cancer mortality by one-fifth (2.). However, such screening is currently not recommended due to the extent of unnecessary follow-up measures that are used. The screening of lung cancer is being studied through renewed testing methods in the Netherlands and other countries.
Ovarian cancer and gastric cancer
An extensive evaluation of ovarian cancer screening is currently underway and the mortality estimates will be completed in the next few years (3.). Gastric cancer screening has been studied in countries with high incidence of this cancer (4.). In countries with a low rate of gastric cancer such as Finland, screening is not considered necessary.
