A new report from the American Cancer Society paints a complex picture of cancer trends, revealing both strides in mortality reduction and alarming increases in cancer diagnoses among younger women.
While overall cancer death rates have fallen by an impressive 34% between 1991 and 2022, diagnoses of certain cancers are rising, particularly among women under the age of 65. This trend highlights a concerning shift in the burden of cancer toward younger and middle-aged women, a demographic historically considered lower-risk.
The Rising Cancer Burden Among Women
According to the report, cancer incidence rates among women under 50 were 82% higher than their male counterparts in 2021, up from 51% in 2002. Women aged 50-64 are also being diagnosed with cancer at higher rates than men in the same age group.
Breast cancer, in particular, is driving much of this increase. For women under 50, breast cancer diagnoses have been rising at a rate of 1.4% annually since the mid-2000s, compared to a 0.7% yearly increase in older women.
The reasons behind these rising rates remain unclear, though experts suggest factors such as environmental exposures, lifestyle changes, hormonal influences, and delayed childbirth may play a role.
Rebecca Siegel, Senior Scientific Director of Surveillance Research at the American Cancer Society, highlighted the societal implications of these findings:“While reductions in cancer mortality due to better treatments and early detection are encouraging, rising cancer rates in young and middle-aged women, who are often family caregivers, represent a significant shift in the cancer burden from men to women,” Siegel said.
Advances in Treatment and Early Detection
The decline in cancer deaths is a testament to advancements in medical technology and public health efforts. Enhanced screening techniques, early detection, and improved treatments have all contributed to better survival rates. For example, innovations in breast cancer screening, such as 3D mammography, have allowed for earlier diagnosis and intervention.
However, the rise in early-onset cancers raises questions about current screening guidelines. Younger women, who may not meet the age criteria for routine screenings, could benefit from earlier or more personalised screening strategies based on risk factors.
Racial Disparities in Cancer Outcomes
The report also highlights significant racial inequities in cancer incidence and mortality. Black and Native American women face much higher death rates from certain cancers than their white counterparts.
Cervical cancer, for instance, is considered highly treatable with routine pap smears and HPV vaccination. Yet, it disproportionately impacts Black and Native American women, who die from the disease at rates two to three times higher than white women. These disparities often stem from unequal access to preventive care, screenings, and treatment.
The Importance of Women-Centric Research
The rising cancer rates among younger women underscore the need for more women-focused cancer research. Historically, medical studies have centred on men, leaving gaps in our understanding of how certain cancers uniquely affect women.
Additionally, addressing lifestyle factors and systemic barriers to care—such as access to screenings, financial constraints, and workplace accommodations for women undergoing treatment—will be critical in reversing these trends.
A Call to Action
With over 2 million new cancer cases projected in 2025 and more than 600,000 deaths expected, urgent action is needed to address these shifting trends. Women, particularly younger and middle-aged, must be empowered with education, access to early screenings, and tailored treatment options.
As cancer’s burden increasingly shifts toward women, particularly those under 65, this challenge must be met with heightened awareness, equitable healthcare access, and continued research focused on women’s unique needs.
