Cancer treatments based on the internal clock could improve outcomes
Every cell in the human body operates on an intricate internal schedule, governed by circadian rhythms that synchronize our biological processes with the 24-hour cycle of day and night. Coordinated by a master clock in the brain called the suprachiasmatic nucleus, these cellular clocks control essential bodily functions including sleep-wake cycles, hormone production, immune function, and metabolism. When these internal clocks are disrupted, the consequences can be profound, potentially increasing our vulnerability to diseases including cancer.
