7. CONCLUSION It is becoming quite clear that the etiology of human breast cancer is exceedingly complex, with probable multiple factors involved in its etiology. Molecular epidemiology and the use of markers of susceptibility, internal dose, and early effects may elucidate not only mechanisms, but also clarify relationships between risk factors and disease among subsets of the population who are specifically at risk. For the public, however, lifestyle modification to maintain normal weight, eat a diet high in fruits and vegetables, and refraining from tobacco use and alcohol consumption, should be advised for all women, regardless of genetic makeup.
