Nearly one in four breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. This study follows the literature review methods and format. Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies …

While there is evidence that breast cancer risk is positively associated with body mass index (in postmenopausal women) and energy intake and inversely associated with physical activity, few studies have examined breast cancer risk in association with energy balance, the balance between energy intake and expenditure. Therefore, in the cohort study reported here, we studied the independent and combined associations of vigorous physical activity, energy consumption, and body mass index (BMI), with breast cancer risk. The investigation was conducted in 49,613 Canadian women who were participants in the National Breast Screening Study (NBSS) and who completed self- administered lifestyle and …

It is thought that oxidative stress resulting to repeated ovulation may increase the risk of ovarian cancer by inducing DNA damage (1). Consumption of antioxidants may, therefore, decrease ovarian cancer risk by counteracting oxidative stress and the resultant DNA damage (2, 3). Currently, the epidemiologic evidence regarding associations between antioxidants and risk of ovarian cancer is mixed (4-12). Of the two prospective studies, Kushi et al. (4) and Fairfield et al. (7) both reported no association between β-carotene and ovarian cancer risk. In addition, Fairfield et al. …
