Cancer on the Rise in Younger Women

Written by 9News | May 22, 2025

The American Cancer Society reports a troubling increase in breast, colon and lung cancers among women under 50. CU professor Ashley Cartun’s diagnosis at 39—after years of proactive screenings—underscores the importance of knowing your risk and staying on top of your health.

CU Cancer Center Member Virginia Borges, MD, a specialist in young women’s breast cancer, notes a surge in aggressive cases among women under 45. While the exact cause remains unclear, lifestyle changes like reduced alcohol intake, regular exercise and a balanced diet can help lower risk.
