MyPeBS (My Personal Breast Screening) is a clinical trial that is currently in progress.
This European trial, which is expected to last 6 years and enroll 80,000 women, is designed to assess the interest of individualized screening based on personal risk of developing breast cancer.

At first glance, this clinical trial appears to be of interest. Unfortunately, when we examine the protocol, we quickly notice that the trial's promoters have a clear pro-screening bias. And because of this bias, they made questionable decisions, resulting in serious flaws in MyPeBS.

Of course, these flaws are not mentioned on the official MyPeBS website. Nonetheless, it appears to me that both the doctors who are asked to be investigators and the women who are offered to participate in the trial have a right to complete information on MyPeBS's strengths and weaknesses.
We can rely on the MyPeBS official website for the strengths. This website's vocation is to address the flaws.

Furthermore, it is difficult to make an informed decision about MyPeBS without first understanding the current uncertainties surrounding the benefit/risk ratio of breast cancer screening as it is currently practiced. For this reason, a section of the site is dedicated to an overview of breast cancer screening.

This website is divided into three sections :

- a critical analysis of MyPeBS

- a critical analysis of current breast cancer screening methods

- updates on MyPeBS and breast cancer screening
