Processed Food Linked to Poorer Cancer Outcomes

Despite having similar or lower breast cancer rates compared to White women, Black women in the United States continue to die from the disease at significantly higher rates. According to Rutgers University, a new study suggests that diet, specifically the intake of processed meat, may play a larger role in these outcomes than previously recognized.

The research, published in The Lancet Regional Health, Americas, followed Black women with breast cancer and tracked the relationship between food choices and survival. According to lead author Dr. Tengteng Wang, greater consumption of ultra-processed foods was associated with a higher risk of death, both from any cause and from breast cancer itself. Processed meats like bacon, hot dogs and deli slices were identified as the strongest contributors to this risk.

These foods are high in sodium and saturated fat and contain preservatives and additives known to promote inflammation and oxidative stress, factors that may worsen cancer progression. According to Dr. Wang, even though the overall diet of the women studied was similar to that of other Western populations, processed meat stood out as a consistent problem.

The findings could help explain part of the survival gap. Black women are more likely to be diagnosed with aggressive subtypes of breast cancer and may also face higher rates of metabolic and inflammatory conditions at the time of diagnosis.

While no single change will close the disparity, Dr. Wang suggests that patients focus on one simple takeaway: limit or avoid processed meat. “If you can’t do everything,” she said, “at least limit this one thing.”

Other experts echoed the importance of culturally grounded guidance. According to Dr. Elisa Bandera, also with Rutgers, returning to traditional home-cooked meals could be both cost-effective and protective.

As this research gains traction, providers, including pharmacists and care coordinators, may begin to incorporate basic nutrition messages into survivorship plans. According to Rutgers University, even small changes in food choices may support long-term health in a meaningful way.
