To date, studies investigating the association between dairy consumption and breast cancer in women have produced conflicting results. As diet is an important, modifiable factor affecting cancer development, the aim of this study was to examine the association between dairy consumption and breast cancer risk. PubMed, Embase, and Cochrane Library databases were searched with a priority for prospective cohort studies. Case-control studies were also considered in case of the absence of a cohort study. We analyzed 22 prospective cohort studies 1,, participants and five case-control studies 33, participants. A significant linear relationship between dairy consumption and breast cancer risk was found on dose-response analysis.
Breast Cancer Research Results and Study Updates
Targeted Therapy for Breast Cancer
Health outcomes in developed countries differ substantially for mothers and infants who formula feed compared with those who breastfeed. For infants, not being breastfed is associated with an increased incidence of infectious morbidity, as well as elevated risks of childhood obesity, type 1 and type 2 diabetes, leukemia, and sudden infant death syndrome. For mothers, failure to breastfeed is associated with an increased incidence of premenopausal breast cancer, ovarian cancer, retained gestational weight gain, type 2 diabetes, myocardial infarction, and the metabolic syndrome. Obstetricians are uniquely positioned to counsel mothers about the health impact of breastfeeding and to ensure that mothers and infants receive appropriate, evidence-based care, starting at birth. Health outcomes differ substantially for mothers and infants who formula feed compared with those who breastfeed, even in developed countries such as the United States. A recent meta-analysis by the Agency for Healthcare Research and Quality reviewed this evidence in detail 1 :. For infants, not being breastfed is associated with an increased incidence of infectious morbidity, including otitis media, gastroenteritis, and pneumonia, as well as elevated risks of childhood obesity, type 1 and type 2 diabetes, leukemia, and sudden infant death syndrome SIDS.
Factors with Unclear Effects on Breast Cancer Risk
Men with breast cancer may be more likely to die of the disease than women, particularly during the first 5 years after diagnosis, a new study suggests. The higher likelihood of death was linked in part to undertreatment and later diagnosis. In a survey of nearly breast cancer survivors, researchers found that the cost of care factored into the decisions the women made about what type of surgery to get. Many women also reported never discussing costs with their physicians.
However, you may have some long-term side effects. New side effects may occur months or even years after treatment ends. Talk with your health care provider about any health issues you have. Although some conditions such as early menopause cannot be reversed, the symptoms can be treated.
