- Your medical records. This includes doctors' notes and pathology reports. Pathology reports are your laboratory test results from any biopsies, surgeries, or screening examinations, such as colonoscopies.
- A list of family members that includes each person’s current age or age at the time of death and cause of death. This list should include parents, siblings, children, aunts, uncles, nieces, nephews, grandparents, and cousins.
- Information on specific types of cancer that have been diagnosed in the family. This should include the age at which family members were diagnosed with cancer. Pathology reports are often helpful.
Although having this information is very helpful, it is not necessary. You should not avoid genetic counseling just because you do not know a lot about your family history.
When going to the appointment, consider taking someone with you. This may or may not be a family member, depending on your preference. The genetic counselor will discuss a lot of information. Another person can help you listen and think of questions. If you choose to bring a family member, that person may also be able to provide information about your family history.

What to expect after the appointment
Your genetic counselor will usually give you written information relevant to your family history and any genetic testing options discussed.

When the test results are available, your genetic counselor can review them with you and help you understand them.
