Drawing a Family Tree or Pedigree
There are different ways of recording your family health information. Pictured are two examples: a pedigree drawing and a family history questionnaire.
A pedigree is the term given by genetic counsellors and genetic specialist for a family tree. It gives a visual overview of the family’s cancer history.
The easiest way to record your family cancer history is to download the Sydney Cancer Genetics Family History Questionnaire.
What Information Do I Need?
The key things you need for each relative are:
- Their full Name and Date of Birth (or approximate age)
- If they had cancer, record how old they were they when diagnosed and what type it was
- For relatives who have died, record their age and cause of death
If you don't have a lot of information about your relatives, don't worry. Just record what you know and give an estimate of how old relatives were when they died.
Some documents that can be helpful regarding any cancer in your family are:
- Doctors’ letters describing the type of cancer and any treatment
- Pathology reports about the type of cancer
- Death certificates
