Family Health History

Families have many factors in common, including their genes, environment, and lifestyle. Looking at these factors can help decide whether you have a higher risk for certain health problems, such as heart disease, stroke, and cancer.

Your family health history is a cost-effective "genetic test." Start by talking to your relatives about their health conditions and habits. Then draw a family tree and add their health information, or use My Family Health Portrait to build a basic family health history online.

Save, print, and share your record with relatives and your health provider. When available, also share copies of your personal health records with your health professional.
