PI3K protein is abnormally high in breast precancerous lesions. This preclinical study demonstrates that the FDA-approved anti-PI3K inhibitor alpelisib can prevent breast cancer and thus warrant future clinical trials in high-risk women.

The findings of this study do not support a major role for the metabolic gut hormones ghrelin and PYY in colorectal cancer development but suggest the possibility of an involvement for ghrelin in specific tumor subtypes. Elucidating subtype-specific risk factors and mechanisms of carcinogenesis may have implications for precision prevention.

Understanding the 3-year yield of mt-sDNA for colorectal cancer and advanced precancerous polyps is required to ensure the clinical appropriateness of the 3-year interval and to optimize mt-sDNA's screening effectiveness.

This study documents the concerns of the age-based changes in screening guidelines on the identification of higher grades of cervical intraepithelial neoplasia and their determinants in women diagnosed with abnormal Pap smear and emphasize the need for targeted screening of younger women to prevent cervical cancer.

Neither vulvovaginal candidiasis nor bacterial vaginosis was found to increase the incidence of cervical cytologic abnormalities with or without the presence of HPV. On the contrary, bacterial vaginosis may play a role in preventing cytologic abnormalities in women with HPV coinfection.

F. nucleatum is well known as a colorectal cancer–associated bacterium. Dietary habits alter the composition and function of the intestinal microbiota. A high intake of dairy products in healthy adults may reduce F. nucleatum and prevent colorectal cancer.
