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

The cost of a genetic test for cancer risk varies widely: single-gene tests (e.g., BRCA1/2) range from 200–500 €, while comprehensive panels or whole-genome sequencing can exceed 1000 €. MyBody-X does not offer diagnostic cancer genetic tests; its products focus on nutrigenetics and longevity. As for microbiome tests: current evidence does not support their use for cancer diagnosis or risk prediction. Some mechanistic studies suggest gut microbiota may influence colorectal cancer development, but human data are limited and controversial. A microbiome test cannot replace established screening methods (colonoscopy, mammography). Evidence level: mechanistic/unclear. Caveat: Do not rely on direct-to-consumer tests for cancer decisions; consult a physician for proper risk assessment and screening.
