GLP-1 medications linked to lower breast cancer risk in women

A retrospective analysis of more than 110,000 women between the ages of 45 and 80 found that those who took GLP-1 medications were about 30 percent less likely to develop breast cancer than those who did not take GLP-1 medications, according to research presented today at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract 10506) by Elizabeth McDonald, MD, PhD, a professor of Radiology in the University of Pennsylvania Perelman School of Medicine and a practicing breast radiologist at Penn's Abramson Cancer Center.

Genetic testing finds breast cancer risks that standard screening models miss

Population-based pathogenic variant testing identified breast cancer susceptibility gene carriers who would often be missed by clinical risk models, even when polygenic risk scores were added. In the WISDOM Study analysis, fewer than 1% of high-penetrance variant carriers would have received the same high-risk screening recommendation using clinical plus polygenic risk alone.

Study evaluates statistical models for estimating breast cancer risk

Researchers from Trinity College Dublin, St James's Hospital, and collaborating institutions have carried out the most comprehensive review to date of tools used to estimate breast cancer risk in women with a family history of the disease.

Gene test helps many breast cancer patients avoid chemotherapy

Many people with breast cancer can safely avoid chemotherapy with the use of a gene test, potentially sparing them unnecessary side effects without increasing the risk of the cancer returning, a large international clinical trial led by UCL has found.

Survey reveals critical knowledge gaps in maternal health recommendations

Most Americans know that how well a mother takes care of herself before and during pregnancy affects the health of a baby, but many people remain unclear about some specific maternal health recommendations, including when to start avoiding alcohol, according to a new nationally representative survey from the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

Researchers link surgical weight loss to reduced female cancer mortality rates

Substantial and sustained weight-loss has been linked to a reduced risk of cancer and cancer-related death, mainly in women. Two new studies now provide clues to why the risk is reduced - and suggest that gender, metabolism and genetics may play a crucial role.

Explainable AI could make breast cancer drug predictions safer and clearer

AI-driven genomic analysis could help researchers identify existing drugs that may be repurposed for subtype-specific breast cancer treatment. The review proposes an interpretability-driven framework that links multi-omics data, mechanistic validation, and clinical translation to make AI predictions more transparent and clinically useful.
