The accuracy of home cancer tests varies depending on the type of test and the specific cancer being tested. For example, the Cologuard test has shown high sensitivity for detecting colorectal cancer, but it can also produce false positives. Genetic tests for cancer risk, such as those for BRCA mutations, are highly reliable but can only indicate increased risk, not the presence of cancer itself. Users should always discuss the results with a healthcare professional for proper interpretation and follow-up.
