Abstract:
A prospective epidemiologic study found a threshold level for serum vitamin B12, below which an increased risk of breast cancer among postmeno-pausal women was observed. This is the first observation to suggest that B12 status may influence breast carcinogenesis and therefore may be a modifiable risk factor for breast cancer prevention.
