Scientists have identified a potentially significant mechanism by which fructose, a sugar widely present in sweetened foods and beverages, may promote the spread of aggressive ovarian cancer. According to the research, cancer cells that survive chemotherapy release fructose, which weakens the bonds holding neighboring tumor cells together and thereby facilitates the spread of the disease. The findings add to a growing body of evidence linking dietary sugar to cancer progression and raise questions about nutritional guidance for patients undergoing treatment.
Preclinical experiments further indicated concerning effects associated with high dietary fructose levels and with cholesterol-lowering statins, though the researchers caution that the results require validation in human studies before clinical recommendations can be made. The study does not establish that fructose directly causes cancer spread in patients, and experts stress that patients should not alter prescribed statin regimens without medical advice. The team says the work could inform future strategies for limiting cancer metastasis, and independent scientists have called for follow-up research to clarify the biological pathways involved and their relevance to human disease.
