Family History Collection Tips and Tools

Family History Collection Tips

Use the attached forms to capture family cancer history. First determine who is in the family. Include at least parents, children, siblings, grandparents, aunts/uncles and first cousins. Expand to more distant relatives when it will help clarify patterns, or when there is an exceptional cancer history, such as very early age of onset or rare cancers. Once you have determined family structure, ask about cancer history. When time permits, consider including other notable family history, such as birth defects, distinctive physical features, and intellectual disability or autism. 

Family structure: 

  • Verify relationships, including half and step siblings, adopted individuals, and assisted reproduction with donor gamete.
  • Ask about both paternal and maternal sides of the family 
  • Include unaffected and deceased relatives which can modify risk calculations by a genetics professional
  • Don’t forget to ask about ancestry

Disease expression: 

  • When possible, clarify the location and type of cancer
  • Ask about the presence of bilateral disease or multiple primary tumors 
  • Indicate approximate ages of diagnosis and death 
  • Indicate whether significant environmental risk factors are present. 
  • Assess the family’s level of certainty about the diagnosis (ie. are they sure it was ovarian cancer and not cervical or another female cancer?)

Family History Collection Resources

There are many different approaches to collecting family history information. Recording information in a pedigree can help you visualize patterns of disease more easily, which is one reason genetics experts prefer them. There are also online tools available that allow patients to input their family history information at home and print it out for you to review. Find a tool that helps you collect sufficient information and update it, as family history information changes over time.
