[Testis cancer screening? Don't do it].

At the end of 2022, the Erasmus Medical Centre (Rotterdam) drew attention to testicular cancer with the 'Balls alarm' campaign. Testicular cancer is the most common cancer in young men. They were called upon to do a monthly self-examination. There are some caveats to this campaign. First, the alleged increase in the incidence of testicular cancer is not accurate. Second, on the basis of evidence-based research and the use of the criteria of Wilson and Jungner, testicular screening by self-examination appears to be ineffective. And thirdly, the opportunistic comparison with periodically self-examination of breasts does not hold true because this has proven to be ineffective as is stated by authoritative organizations in the Netherlands.
