One possible...: Risk factor. Family history of breast cancer in mother, sister or daughter is a higher breast cancer risk factor. Other factiros can be young age at first menses, late age at first childbirth, prolonged use of female hormone medication, etc. By itself, young age at fist menses is only a minor factor.
