On November 14, 2026, Dr. Paola Marignani gave a talk at the 3rd International Conference on Young Women’s Breast Cancer and Health (YWBCH 2026) in Tokyo, Japan.

Her talk, “Chronic Low Dose Exposure to Endocrine Disruptors and the Rise of Early-Onset Breast Cancer,” examined how long-term exposure to low doses of endocrine-disrupting chemicals may contribute to the increase in breast cancer among young women.

Dr. Marignani spoke in the Basic Science & Biology session, chaired by Dr. Takayuki Ueno of The Cancer Institute Hospital of JFCR and Dr. Rakesh Kumar of the Breast Cancer in Young Women Foundation. The session also included talks by Dr. Kouya Shiraishi of the National Cancer Center Research Institute, Japan, on the genomics of early-onset breast cancer, and Dr. Kousuke Kawaguchi of Mie University on the tumour immune environment.

The conference is organized by the Breast Cancer in Young Women Foundation, a network of clinicians, researchers, advocates, and survivors in 29 countries, and hosted by the Japan Breast Cancer Research Group. The program brought together specialists in basic science, clinical care, fertility, survivorship, and patient advocacy.
