Oncologist's Take: Are At-Home Genetic Tests Worth It?

At-home genetic tests for cancer risk can provide insights into inherited genetic mutations linked to certain cancers, but they have limitations. Only 5-10% of cancers are associated with inherited variants, and commercial tests often detect a limited range of mutations. It's advisable to consult a doctor for comprehensive screening if there's a family history of cancer. Consider the emotional and practical implications of test results, as they may not always influence treatment decisions. Additionally, genetic mutations can occur with age, increasing cancer risk, but interventions are available to mitigate this risk.
