The connection between cancer and metabolic disorders is becoming increasingly apparent, as cancer can alter the body’s metabolism in complex ways. For example, many cancer cells exhibit altered metabolic pathways, which allow them to thrive in hostile environments. These changes often lead to weight loss, cachexia, and insulin resistance, complicating treatment and recovery. Research is focusing on understanding how metabolic disruptions contribute to cancer progression and how targeting these pathways can offer new therapeutic options. Metabolic therapies, such as those that restore normal glucose metabolism or address mitochondrial dysfunction, are being explored in clinical trials. Additionally, lifestyle interventions, including diet and exercise, are being investigated to support cancer patients' overall metabolic health and improve treatment outcomes.
