Prostate cancer is the most common type of cancer for Dutch males. 1 out 9 males is diagnosed with prostate cancer during his life. 48% Of the diagnosis is for men older than 70 (IKNL, 2014). Antoni van Leeuwenhoek hospital and Nederlands Kanker Instituut do research in cancer diagnostics. This graduation project focuses on the development of a device that should enable prostate cancer patients to collect their own blood sample within their home. The sample will be analyzed at the hospital for “prostate specific antigen” (PSA). The results of such measurements determine the patients treatment. The system should omit patient visits to the hospital for such PSA checks.
