welche untersuchungen ab 50 — can a DNA test help?

From age 50, standard screenings in Germany include colorectal cancer screening (colonoscopy or stool test), mammography (women), skin cancer screening, and cardiovascular check-ups. A DNA test can provide additional risk information – for example, the rs7903146 variant in TCF7L2 is associated with type 2 diabetes risk, and skin DNA tests (like MyBody-X's skincare test) claim to predict aging traits. However, individual genetic variants usually have small effects, and the evidence is mixed: some markers have moderate human studies, others only mechanistic or marketing claims. DNA tests should never replace routine medical screenings. They can be a complementary tool, but always discuss results with a doctor. Caveat: Many direct-to-consumer tests overstate genetic influences.
