More women are hearing the words ‘late-stage, invasive breast cancer’ when they’re initially diagnosed, a new study finds.
Late-stage breast cancer, which has metastasized or spread to other parts of the body, is much harder to treat.
The five-year survival rate is 31% compared to 99% for localized breast cancer and 86% for regional invasive disease.
Researchers used data from the National Cancer Institute to evaluate late-stage diagnosis trends between 2004 and 2021.
The results showed women 20-39 years of age experienced the largest annual increase in late-stage breast cancer diagnosis at initial presentation (2.9%). But worrisome upward trends were also seen in women 40-74 years of age and 75+.
The lead author says, “The significant increase in metastatic disease at diagnosis among all U.S. women and across all age groups is an alarming new finding.”
And the results show women of all ethnicities are being impacted.
The researchers say inconsistent screening guidelines, which discourage attendance, may be one driving force.
“Fewer than 50% of U.S. women participate in annual breast cancer screening,” according to another author.
The U.S. Preventive Services Task Force (USPSTF) currently recommends women between 40 and 74 undergo a screening mammogram every two years.
The National Comprehensive Cancer Network recommends screening every single year starting at 40 if you’re at average risk.
Other factors that may be impacting the increase in late-stage diagnosis include obesity, reproductive trends, a lack of access to quality health care and environmental factors.
The researchers say more study is needed, especially among Black women, who face a higher risk of advanced breast disease at a younger age.
