🚨 New research shows fructose, helps cancerous tumors spread. When chemotherapy damages ovarian cancer cells without completely destroying them, some enter a state known as senescence, where they stop dividing but remain biologically active. A new preclinical study from The Wistar Institute has revealed that these surviving cells produce and release fructose, which neighboring cancer cells readily absorb. This absorption alters the way target cells process energy and dramatically lowers cholesterol in their outer membranes. Since cholesterol acts as a vital cellular glue keeping cells anchored together, this depletion allows neighboring cancer cells to detach and easily spread throughout the abdominal cavity. In animal trials, mice given high levels of fructose in their drinking water developed significantly more metastatic nodules than those given glucose. Furthermore, clinical samples from patients with high-grade serous ovarian cancer showed a correlation between elevated circulating fructose levels and advanced stages of the disease. While researchers caution that these preclinical findings do not mean eating fresh fruit causes cancer to spread—as whole fruit contains fiber and other vital nutrients—the discovery opens a promising new avenue. Scientists are already investigating if this fructose-driven mechanism also fuels the progression of pancreatic, colon, and liver cancers. source: Cole, A. R., et al. (2026).
