Health care professionals have known for a long time that common diseases - heart disease, cancer, and diabetes - and even rare diseases - like hemophilia, cystic fibrosis, and sickle cell anemia - can run in families. If one generation of a family has high blood pressure, it is not unusual for the next generation to have similarly high blood pressure.

Tracing the illnesses suffered by your parents, grandparents, and other blood relatives can help your doctor predict the disorders to which you may be at risk and take action to keep you and your family healthy.

Americans know that family history is important to health. A recent survey found that 96 percent of Americans believe that knowing their family history is important. Yet, the same survey found that only one-third of Americans have ever tried to gather and write down their family's health history.

Because family health history is such a powerful screening tool, the Surgeon General has created a new computerized tool to help make it fun and easy for anyone to create a sophisticated portrait of their family's health.

This new tool, called "My Family Health Portrait" can be downloaded for free and installed on your own computer.

The tool will help you organize your family tree and help you identify common diseases that may run in your family.

When you are finished, the tool will create and print out a graphical representation of your family's generations and the health disorders that may have moved from one generation to the next. That is a powerful tool for predicting any illnesses for which you should be checked.
