According to the latest report from the American Cancer Society (ACS), over 310,000 women in the United States are expected to receive an invasive breast cancer diagnosis this year. Alarmingly, there has been a notable increase in breast cancer cases among women aged 50 and younger, highlighting a pressing public health concern.
Understanding the statistics
The report titled “Breast Cancer Statistics, 2024,” published in CA: A Cancer Journal for Clinicians, reveals that while breast cancer mortality rates have decreased by 44% since 1989, the incidence of breast cancer in younger women has risen by 1% annually from 2012 to 2021. This trend is particularly concerning as it suggests that future advancements in reducing mortality could be hindered by the increasing number of diagnoses.
In 2024, it is estimated that approximately 310,720 women will be diagnosed with invasive breast cancer, and around 42,250 will succumb to the disease. Angela Giaquinto, the lead author of the report and an ACS associate scientist, emphasizes that the progress made in reducing mortality rates could be compromised by the rising incidence, especially among younger demographics, compounded by the impacts of the COVID-19 pandemic, which has led to delays in screening and diagnosis.
Disparities in breast cancer outcomes
Breast cancer is the second most common cancer among women in the U.S., following skin cancer. However, significant disparities persist, particularly among Asian American, Pacific Islander, Native American and Black women. Dr. William Dahut, ACS chief scientific officer, points out that Black women experience a 38% higher breast cancer mortality rate compared to their white counterparts. This alarming statistic underscores the urgent need for systemic changes to ensure equitable access to high-quality screening and treatment for all women.
In response to these disparities, the ACS launched the VOICES of Black Women study in May, which aims to investigate cancer and health disparities affecting Black women in the U.S. This groundbreaking study, the largest of its kind, will span a minimum of 30 years and involve a diverse team of researchers who will engage participants through biannual surveys, gathering valuable insights throughout the study’s duration.
Factors contributing to increased diagnoses
The reasons behind the rising prevalence of breast cancer in younger women are complex and multifaceted. Dr. Christopher McGreevy, an associate chief of breast surgery at Hackensack University Medical Center, notes that factors such as obesity, delayed childbearing, environmental toxins and genetics may contribute to this trend. Additionally, some researchers attribute the increase to systemic racism, which can lead to delays in diagnosis and inadequate access to timely cancer treatment.
The ACS report utilized data from reputable sources, including the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program, the Centers for Disease Control and Prevention’s National Program of Cancer Registries (NPCR), and the National Center for Health Statistics. This comprehensive analysis underscores the importance of ongoing research and data collection to better understand and address the rising rates of breast cancer.
A call for action
The rising incidence of breast cancer among younger women is a critical issue that demands immediate attention. As we continue to make strides in cancer research and treatment, it is essential to address the disparities that exist within our healthcare system. Ensuring access to quality screening and treatment for all women, particularly those in marginalized communities, is vital in the fight against breast cancer.
