An increase in breast cancer rates in women under 40, described as ‘alarming’, has been reported across the United States. Research conducted by experts from Columbia University’s Mailman School of Public Health has revealed a concerning surge of up to 32% in some regions. The study examined data from all 50 states, indicating a general upward trend in breast cancer cases among women under the age of 40. The Northeast region showed the most significant rise in rates between 2001 and 2020, with the highest absolute rate of breast cancer in this age group.

Dr. Rebecca Kehm, the study’s first author and assistant professor of Epidemiology at Columbia Mailman School, highlighted the significance of these findings. She expressed that while breast cancer incidence is on the rise in young American women, it was previously unclear whether these trends varied geographically within the US. The study aims to shed light on whether different environmental exposures prevalent across various regions may contribute to the heightened risk of breast cancer in younger women.
Among the states with the highest early-onset breast cancer incidence during the period from 2001 to 2020 are Maryland, New York, New Jersey, Hawaii, and Connecticut. These states exhibited rates that were 32% higher compared to those with the lowest incidence. Dr. Kehm emphasised that the escalating incidence of breast cancer in this demographic is concerning and cannot be solely attributed to genetic factors or changes in screening practices. Notably, women under 40 are generally not recommended for routine mammography screenings.
The recommendation for women to begin mammogram screenings at age 40 is a relatively recent development, with the U.S. Preventive Services Task Force advising all women to undergo screenings starting at this age, irrespective of their family history. While most insurance plans cover routine mammograms, the CDC’s National Breast and Cervical Cancer Early Detection Program offers screenings and services to uninsured women or those falling below the federal poverty limit. Access to screening providers can be found through their online directory.
Breast cancer awareness and early detection are crucial in combating the disease. The findings from this research underscore the importance of understanding regional variations in breast cancer incidence among young women. Through continued research and awareness, initiatives can be developed to address the rising rates and promote proactive measures for early detection and intervention.
This alarming rise in breast cancer rates among women under 40 serves as a stark reminder of the importance of regular health screenings and awareness. By staying informed and proactive, individuals can take steps towards early detection and treatment, ultimately improving outcomes in the fight against breast cancer.
