Circadian rhythms, our internal biological clocks, play a crucial role in regulating various physiological processes. Disruptions to these rhythms have been increasingly linked to the development of several types of cancer, including lung, breast, colorectal, leukemia, hepatocellular carcinoma and glioblastoma.

The causes of circadian disruption are multifaceted, often stemming from the modern lifestyle. Factors such as sleep deprivation, nighttime light exposure and irregular eating habits may all lead to disturbances in our internal clocks. These disruptions may impact the cell cycle, genomic stability and immune function—for instance, in colorectal cancer (CRC), lower levels of these clock genes are associated with reduced overall survival rates, highlighting the critical importance of maintaining a healthy circadian rhythm.

To address this pressing issue, healthcare professionals must explore novel strategies for the early detection and prevention of cancer linked to circadian disturbances. Biomarkers, such as the expression levels of core clock genes, may hold the key to identifying individuals at higher risk and implementing targeted interventions. Additionally, the development of precise diagnostic tools and the implementation of effective lifestyle modifications, such as optimizing sleep patterns, managing light exposure and maintaining regular eating habits, can potentially reduce the risk of cancer development and improve patient outcomes.

In conclusion, the emerging field of research on the connection between circadian disruption and cancer highlights the critical importance of maintaining a healthy internal clock for overall well-being. As scientists continue to unravel the complex mechanisms underlying this relationship, we must take proactive steps to promote a healthier lifestyle and optimize cancer management approaches, ultimately safeguarding the health and well-being of individuals and communities worldwide.
