Cancer screening tests offered as add-on services may cause harm without clear benefits. Healthcare providers must inform patients about potential risks and uncertain advantages for informed decision-making.
Area of Science:
- Oncology
- Health Services Research
- Medical Ethics
Context:
- Cancer screening tests like ultrasound, skin, and PSA tests are common out-of-pocket services in Germany.
- These services, known as Individuelle Gesundheitsleistungen (IGeL), supplement statutory health insurance coverage.
- Many cancer screenings are not covered by insurers due to unclear or unfavorable benefit-harm profiles.
Purpose:
- To outline the challenges and criteria for assessing the benefits of cancer screening tests.
- To highlight the importance of transparency regarding the benefits, harms, and uncertainties of cancer screening tests.
- To emphasize the ethical obligation of healthcare providers in informing patients about IGeL cancer screenings.
Summary:
- Cancer screening tests offered as individual out-of-pocket services carry potential harms.
- The benefits of these screenings are often unclear, contested, or non-existent.
- A thorough benefit assessment is crucial for determining the value of these tests.
Impact:
- Informed patient decision-making regarding cancer screening is paramount.
- Healthcare providers must disclose comprehensive information on benefits, harms, and uncertainties.
- This ensures ethical practice, particularly for supplementary health services like IGeL.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
