Genetic testing is a medical process that examines your DNA to identify changes or mutations that may lead to certain health conditions. This testing can help determine if you are at risk for inherited diseases, such as cystic fibrosis or Huntington's disease. It can also provide information about your ancestry and traits, making it a valuable tool for both health and personal curiosity. The results of genetic testing can guide decisions about medical care and lifestyle choices. For example, if a test shows a high risk for a condition like breast cancer, you might choose to undergo more frequent screenings or consider preventive measures.
