In a study that could help explain the connections between depression and cancer, researchers have used an animal model to find, for the first time, a biological link between tumors and negative mood changes. The team determined that substances associated with depression are produced in increased quantities by tumors and are transmitted to the brain. Additionally, pathways that normally moderate the impact of depression-causing substances are disrupted when a tumor develops.
