title: Importance of follow-up of family history for understanding the genetic background of cancer.
abstract: The details of family histories naturally change as time passes. Thus, the family histories at the time of first consultation are incomplete, particularly in the cases of younger cancer patients whose disease is indicated as having a genetic background on the basis of epidemiological studies. The necessity for follow-up of the family history is illustrated by presenting some clinical cases as examples.
