It can be useful for both the patient and doctor to be aware of the families medical history because testings for and illnesses or medical injuries can be brought down to ensure the bloodline doesn't receive those same issues as well. For example, if the patients grandparents and parents have a history of cancer it is best to screen for cancer in the patient to make sure it hasn't passed down through generations. This is the same for allergies and age.
