 Findings from POSITIVE, the largest known study evaluating "breastfeeding frequency, patterns, and relation to breast cancer outcomes in women previously diagnosed with early, hormone receptor-positive breast cancer" were recently unveiled in the Journal of Clinical Oncology.  According to data reported in the POSITIVE study, breastfeeding was not shown to be associated with a higher short-term rate of breast cancer related events, news particularly relevant to women planning pregnancy and breastfeeding after receiving a breast cancer diagnosis.
