Planning tool
Map what runs in your family
Family health history can add useful context to a clinical conversation. This tool turns what you know into a simple tree you can print, without scoring it, saving it, or drawing conclusions about anyone in the family.

Clinicians may ask which relatives had a condition, the age at diagnosis, and whether a pattern appears across close relatives or one side of a family. The meaning differs by condition and family. This tool deliberately draws no conclusions.

Why doctors keep asking about your family
Relatives share genes, and usually also environments, habits, and food. That is why conditions such as heart disease, type 2 diabetes, and some cancers cluster in families, and why public health agencies recommend collecting your family health history and sharing it with your care team.
Public-health guidance suggests collecting which relatives had which conditions and, when known, their age at diagnosis. A clinician can decide whether a pattern is relevant to assessment, testing, or screening.
Ask relatives only what they are comfortable sharing. This page keeps entries in memory for the current page session, clears them on refresh or navigation, and sends nothing to the server.
Before the appointment
Pair your printed tree with clear expectations about what risk information can and cannot tell you, and how screening decisions are actually weighed.
