Abstract
Each year approximately one million women are newly diagnoses with breast cancer (BC), in Germany 65 new cases per 100.000 inhabitants are registered, yearly. In Egypt , another 100.000subjects are registered also , of whom , 6% are in the pediatric age in addition to 150,000 patients from the year before as reported by the headmaster of tumor’s institute , (October 2004)
The fact that incidence has been rising in parallel with economic development indicates that environmental factors might play an important role in causation of BC. Migrational data have pointed to nutrition ads one of the more relevant external factors involved. Preventive dietary advice often includes a reduction of alcohol, red meat and animal fat and increasing the intake of vegetables, fruits, and fiber, and lately, photo – estrogens from various sources . Clearly, the scientific basis for these recommendations appears sparse. The available prospective data from epidemiological studies and interventional trails do not support the overall hypothesis that higher fat-intakes are a relevant risk factor for BC development.
