What is family history?
Family history refers to health information about you and your close relatives. Family history is one of the most important risk factors for health problems like heart disease, stroke, diabetes and cancer. (A risk factor is anything that increases your chance of getting a disease.) |

Q:
A: |
Why is knowing my family history important?
Family members share their genes, as well as their environment, lifestyles and habits. A family history helps identify people at increased risk for disease because it reflects both a person’s genes and these other shared risk factors. |

Q:
A: |
My mother had breast cancer. Does this mean I will get cancer, too?
Having a family member with a disease suggests that you may have a higher chance of developing that disease than someone without a similar family history. It does not mean that you will definitely develop the disease. Genes are only one of many factors that contribute to disease. Other factors  to consider include lifestyle habits, such as diet and physical activity.
If you are at risk for breast cancer, consider following national guidelines for a healthy diet and regular exercise. It is also important to talk with your physician about your risk and follow recommendations for screening tests (such as mammograms) that may help to detect disease early, when it is most treatable.

Q:
A: |
Because both of my parents had
heart disease, I know I have “bad” genes. Is there anything I can do to protect myself?
First of all, there are no “good” or “bad” genes. Most human diseases, especially common diseases such as heart disease, result from the interaction of genes with environmental and behavioral risk factors that can be changed. The best disease prevention strategy for anyone, especially for someone with a family history, includes reducing risky behaviors (such as smoking) and increasing healthy behaviors (such as regular exercise).

Q:
A: |
How can knowing my family history help lower my risk of disease?
You can’t change your genes, but you can change behaviors that affect your health, such as smoking, inactivity and poor eating habits. People with a family history of chronic disease may have the most to gain from making lifestyle changes . In many cases, making these changes can reduce your risk of disease even if the disease runs in your family.
Another change you can make is to participate in screening tests, such as
mammograms and
colorectal cancer screening, for early detection of disease. People who have a family history of a chronic disease may benefit the most from screening tests that look for risk factors or early signs of disease. Finding disease early, before symptoms appear, can mean better health in the long run. |

How do I learn about my family history if I'm adopted?
Learning about your family health history may be hard if you are adopted. Some adoption agencies collect medical information on birth relatives. This is becoming more common but is not routine. Laws concerning collection of information vary by state. Contact the health and social service agency in your state for information about how to access medical or legal records. The National Adoption Clearinghouse offers information on adoption and could be helpful if you decide to search for your birth parents. To learn more, visit http://www.childwelfare.gov/. |

Q:
A: |
What will my doctor do with the information?
Your doctor will assess your risk of disease based on your family history and other risk factors. Your doctor may also recommend things you can do to help prevent disease, such as exercising more, changing your diet, or using screening tests to detect disease early.

Q:
A: |
If I don’t have a family history of disease, does that mean I am not at risk?
Even if you don’t have a history of a particular health problem in your family, you could still be at risk. This is because you may be unaware of disease in some family members, or you could have family members who died young, before they had a chance to develop chronic conditions. Your risk of developing a chronic disease is also influenced by many other factors, including your habits and personal health history. |
