Before a primary-care visit, make a short list of health conditions among your relatives. Add the age when each condition was diagnosed, if you know it, and mark details you are unsure about. An incomplete family history can still help your provider decide which screenings to discuss and when.
Why family health history matters
Health conditions in a family can reflect shared genes, surroundings, or habits. That history may affect your own risk, but it cannot tell you on its own whether you will develop a condition. Your provider considers it alongside your health and other factors.
Family history can help guide a conversation about screening. If a condition concerns you, tell your provider what you know and ask how it may affect your care. You do not have to interpret the history by yourself.
What to record
Start with close blood relatives on both sides of your family: parents, siblings and half-siblings, children, grandparents, aunts, uncles, nieces, and nephews. For each person, note their relationship to you and any major health conditions you know about. Heart disease, diabetes, cancer, stroke, high blood pressure, and high cholesterol are examples worth asking about. If you know the specific type of a condition, include it. For cancer, record the type rather than writing only “cancer.”
Add the age when each condition was diagnosed. An approximate age or decade is useful when no one remembers the exact age. For relatives who have died, note their age at death and cause of death if you know them. Leave unknown details blank. If you have heard something but cannot confirm it, label it as uncertain so it is not mistaken for a confirmed fact.
A short conversation with a relative who is willing to share may fill in a few gaps. You could ask, “What condition did you have?” “How old were you when it was diagnosed?” and “Did anyone else in the family have it?” Write down the answers on paper or in a private digital note. The free My Family Health Portrait tool is another way to organize the information.
Some relatives may prefer not to discuss their health. Respect that choice and record what you know from other sources.
Bring it to your provider and update it
Take your notes to your appointment or share them through the method your care team recommends. Point out the conditions or ages that concern you, then ask whether the information changes which screenings to discuss or when to start them. Your provider can consider the history with the rest of your health information.
Relatives may receive new diagnoses, or you may learn more after your appointment. Add details when you can confirm them, and share relevant updates at future visits. Keep the list somewhere you can find it.
