was kostet ein gentest für krebs — can a DNA test help?

Costs for a cancer genetic test vary widely: direct-to-consumer (DTC) tests often cost €100–300 but provide no medical diagnosis, only risk indications. Clinical tests (e.g., BRCA1/2) are more expensive (€500–2000+) and require a doctor's prescription. A DNA test can help identify hereditary risks, but most cancers are not monogenic. Evidence for DTC tests is weak; they do not replace screening. Safety note: false reassurance or unnecessary anxiety is possible. Consult a genetic counselor before testing.
