Scientists have discovered that breast cancer can disrupt the brain’s internal clock almost immediately after the onset of cancer, without anyone noticing. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the feedback loop between the brain and body that regulates stress, sleep, and immunity. Remarkably, when the researchers restored the correct […]

The study points to the internal clock as a […]
