A multidisciplinary team of researchers at Princeton University conducted a study to find out what patients diagnosed with breast cancer should eat to ensure the best prognosis. "We took the approach of building identical engineered tumors and culturing them in conditions that mimic the blood composition of patients under different dietary states," author Celeste M. Nelson said. "We were hoping to identify dietary conditions that would slow tumor growth. Instead, we found one dietary condition—a high-fat diet—that sped up tumor growth."
