Romanos-Nanclares A, et al. - Given that sugar-sweetened beverages (SSB) are an acknowledged dietary factor that increases insulin resistance, which may potentially lead to an increased risk of breast cancer (BC), researchers examined the link between baseline consumption of SSB and the incidence of BC among 10,713 Spanish female university graduates (median age: 33 years) from the Seguimiento Universidad de Navarra cohort who were initially free of BC. Trained oncologists confirmed the incidence of BC using medical records, and Cox regression models were used to assess the relationship between SSD consumption categories and the incidence of BC during follow-up. Analyses were stratified by menopausal status. A total of 100 incident cases of BC were confirmed during 106,189 person-years follow-up. Findings demonstrated a direct link between SSB consumption and BC risk among postmenopausal women.
