Animal Research Minute – Could anxiety-prone people have an increased cancer risk?
Well, researchers at Stanford University say cancer spreads more rapidly and is more aggressive in mice with anxiety. Consistent anxiety also makes mice more sensitive to chronic stress and lowers their immune systems. Other studies have linked chronic stress to higher risks for cancer, but this is the first study to biologically connect the high anxiety personality trait to greater cancer threats. This study with mice could have important implications for people who are prone to anxiety.
