Researchers are investigating the link between disrupted circadian rhythms and cancer progression,with early findings suggesting that restoring these rhythms may enhance the effectiveness of cancer treatments and reduce thier side effects. This research builds on studies showing a correlation between chronic circadian disruption and increased cancer risk.
Circadian rhythms and Cancer
Table of Contents
Circadian rhythms are approximately 24-hour cycles that regulate various physiological processes in the body,including sleep,hormone release,and immune function. Disruptions to these rhythms, frequently enough caused by shift work, jet lag, or irregular sleep schedules, can negatively impact health and potentially contribute to cancer development and progression.

Research at the University of Texas Southwestern Medical Center
Researchers at the University of Texas Southwestern Medical Center, led by Dr. John Borniger, are focusing on understanding how tumors disrupt the body’s natural rhythms, rather than directly targeting the cancer cells themselves. Their approach centers on optimizing the patient’s overall physiological health to bolster the body’s natural defenses against cancer.
Dr. Borniger’s team found that simply restoring normal circadian rhythms in mice with cancer slowed tumor growth without the use of traditional anti-cancer drugs. This suggests that a healthy circadian rhythm can, in itself, be a powerful anti-cancer mechanism.
“What’s really cool is that we didn’t treat the mice with anti-cancer drugs,” Borniger stated in a UT Southwestern news release. “we’re focused on making sure the patient is physiologically as healthy as possible. That itself fights the cancer.”
Potential Impact on Cancer Therapies
The research suggests that optimizing circadian rhythms could enhance the effectiveness of existing cancer treatments and reduce their toxicity. Many chemotherapy drugs are most effective when administered at specific times of day, aligning with the body’s natural rhythms.
By improving a patient’s circadian health,doctors may be able to increase the efficacy of these drugs while minimizing harmful side effects. The Food and Drug Administration (FDA) approves drug schedules based on clinical trials, and future trials may incorporate circadian rhythm considerations.
