3. Your family medical history.
A roadmap of your genetic background is crucial information to have for yourself so you know what signs to look for in yourself. Did your grandmother have breast cancer? Did your uncle have a substance use disorder? Any knowledge is useful knowledge. This is especially true if you're seeking a new doctor. Health care providers will likely ask if there's a history of cancer, heart disease and mental health problems at your first appointment, so it's best to be prepared.
