“… 2 In a survey of 5554 women in the United States, only 38.5% were aware that breastfeeding is associated with a reduced risk for maternal breast cancer. 45 Moreover, it has been demonstrated that awareness of the World Health Organization breastfeeding recommendations was associated with adhering to them. 46 , 47 , 48 Consequently, there is room for improvement in raising awareness of breastfeeding recommendations and communicating positive effects of lactation not only on children but also on their mothers.…”

Background Breastfeeding has been robustly linked to reduced maternal risk of breast cancer, ovarian cancer, and type 2 diabetes. We herein systematically reviewed the published evidence on the association of breastfeeding with maternal risk of cardiovascular disease (CVD) outcomes. Methods and Results Our systematic search of PubMed and Web of Science of articles published up to April 16, 2021, identified 8 relevant prospective studies involving 1 192 700 parous women (weighted mean age: 51.3 years at study entry, 24.6 years at first birth; weighted mean number of births: 2.3). A total of 982 566 women (82%) reported having ever breastfed (weighted mean lifetime duration of breastfeeding: 15.6 months). During a weighted median follow‐up of 10.3 years, 54 226 CVD, 26 913 coronary heart disease, 30 843 stroke, and 10 766 fatal CVD events were recorded. In a random‐effects meta‐analysis, the pooled multivariable‐adjusted hazard ratios comparing parous women who ever breastfed to those who never breastfed were 0.89 for CVD (95% CI, 0.83–0.95; I 2 =79.4%), 0.86 for coronary heart disease (95% CI, 0.78–0.95; I 2 =79.7%), 0.88 for stroke (95% CI, 0.79–0.99; I 2 =79.6%), and 0.83 for fatal CVD (95% CI, 0.76–0.92; I 2 =47.7%). The quality of the evidence assessed with the Grading of Recommendations Assessment, Development, and Evaluation tool ranged from very low to moderate, which was mainly driven by high between‐studies heterogeneity. Strengths of associations did not differ by mean age at study entry, median follow‐up duration, mean parity, level of adjustment, study quality, or geographical region. A progressive risk reduction of all CVD outcomes with lifetime durations of breastfeeding from 0 up to 12 months was found, with some uncertainty about shapes of associations for longer durations. Conclusions Breastfeeding was associated with reduced maternal risk of CVD outcomes.

“…Accordingly, nurses, as health educators, should foment healthy life styles and make women aware of the important role of a balanced diet in the prevention of obesity. Moreover, as another means of prevention breast cancer, especially if it is considered the scarce awareness of the breastfeeding protective effects on breast cancer (Hoyt-Austin et al, 2020;Sly et al, 2020), nursing professionals should also encourage women to breastfeed their children for as long as possible and avoid the consumption of harmful, addictive toxins, such those found in cigarettes (Lee et al, 2014) Breast cancer risk factors from patient medical records are a limitation of great importance associated with retrospective chart review studies and can endanger the credibility of the research results. However, most retrospective chart review studies do not discuss medical records deficiencies or the methods implemented to lessen these limitations (Gregory & Radovinsky, 2012;Yawn & Wollan, 2005).…”

Currently, there is controversy concerning potential factors that contribute to the development of breast cancer. Our study analyzed the possible association between weight status, cigarette consumption, lactation period, serum estrogen levels, family history of breast cancer, and age at breast cancer diagnosis. We conducted a retrospective study at a University Hospital in Granada (Spain) by consulting the medical records of 524 women aged 19 to 91 years, all of them diagnosed and treated for breast cancer from 2011 to 2019. Our findings indicated that in non-morbidly obese females who were also non-smokers, a maternal lactation period of more than 3 months ( p = .013) and the absence of family antecedents of cancer ( p = .025) were statistically significant factors that led to a more advanced age at breast cancer diagnosis. Thus, maternal lactation seems to have a potential protective effect on breast cancer.

“…35 In addition, it is well documented that prolonged breastfeeding decreases the relative risk of breast cancer, especially for TNBC. [36][37][38][39] . However, the link between breastfeeding and breast cancer prognosis has been scarcely explored, with conflicting results.…”
