Researchers from the Cleveland Clinic (OH, USA) found that the microbiome present in the breast tissue may be associated with breast cancer (Oncotarget 2017r 8.88122-68138-M005,3: 59) They hope to find a biomarker that will help diagnose faster and more easily breast cancer. Let's suppose that they have already found such an indicator and developed a diagnostic test to detect its presence. Using this test, they examined 100 women with breast cancer and 100 healthy women who were diagnosed with other methods. They received the following results:
| Sick women | Healthy women | |
| Positive test result | 93 | 11 |
| Negative test result | 7 | 89 |
| Altogether | 100 | 100 |
Indicate the incorrect interpretation of these results
