was kostet ein gentest für krebs — what does this mean exactly?

The cost of a genetic test for cancer varies widely depending on the type and provider. Direct-to-consumer (DTC) tests like 23andMe or MyHeritage typically cost between $100 and $300, but they only test for selected risk variants (e.g., BRCA1/2) and do not provide a full cancer diagnosis. Clinical tests ordered by a doctor (e.g., hereditary breast or colon cancer panels) usually cost $500 to $2000 or more, but are often covered by insurance if there is a family history. The question 'what does a genetic test for cancer cost?' is misleading because there is no single test. Importantly, a positive result from a DTC test does not mean you have or will get cancer; it only indicates a possibly elevated risk. The evidence is limited, and many variants have small effects. Genetic counseling is recommended before testing to understand risks and benefits. Evidence: mixed (practice and observational studies).
