Pregnancy and Sweeteners: A Risk for Breast Cancer?

Although some risk factors for breast cancer are known, they do not fully explain the increase observed among young women. Researchers are therefore increasingly looking at other potential influences from our environment, including diet and certain products that are consumed on a daily basis.

With the financial support of the Cancer Research Society (CRS), Julianna Blagih, a researcher at Maisonneuve-Rosemont Hospital, is studying the role of artificial sweeteners, which are often used to replace sugar in foods and beverages. Her project aims to better understand whether exposure to these products during pregnancy and after childbirth could influence the development of postpartum breast cancer.

Using preclinical models and cutting-edge imaging technologies that allow precise analysis of tumors, her team is investigating how these substances may affect interactions between cancer cells and the immune system. This research could help identify new mechanisms involved in disease development and open new avenues for improving breast cancer prevention and protecting as many women as possible.

Thanks to the support of CRS and its donors, innovative projects can come to life. By funding this research, you help advance knowledge about postpartum breast cancer and gain a better understanding of lifestyle-related risk factors. These discoveries are essential for preventing cancer, guiding future recommendations on diet and the environment, and laying the groundwork for strategies that protect women and reduce their risk of developing cancer.
