New Study Links Obesity and Stress to Aggressive Pancreatic Cancer Risk

Obesity alongside heightened stress levels could significantly increase the likelihood of developing one of the most aggressive forms of cancer, findings from a recent study reveal.

Researchers at the University of California, Los Angeles, have uncovered that neurotransmitters associated with stress and hormones linked to obesity can activate CREB, a protein known to promote pancreatic cancer cell growth.

Impact of Diet and Stress on Cancer Development

The research team observed that mice on a high-fat diet had a heightened risk of developing precancerous lesions. The situation worsened for those subjected to additional stress through social isolation, leading to even larger lesion growth.

Notably, the risk associated with stress appeared to be more pronounced in female mice, raising questions about gender-specific vulnerabilities in cancer risk.

Potential for Existing Medications

Based on their results, the researchers suggested investigating the potential of repurposing existing medications aimed at reducing the risks tied to obesity and stress-induced cancer. For example, beta-blockers, which are typically prescribed for high blood pressure, may offer benefits in addressing the mechanisms underlying stress-related cancer growth.

In a recent press release, it was stated that since the beta-adrenergic receptors are pivotal in promoting stress-related cancer, this class of drugs could serve as a preventive measure against obesity- and stress-related cancer risks.

Understanding the Seriousness of Pancreatic Cancer

Pancreatic cancer stands out as one of the deadliest cancer types in the United States, with a disheartening five-year survival rate of only 13 percent. This particularly grim outlook is exacerbated by the disease’s tendency to be diagnosed at more advanced stages.

Dr. Robert Den, a radiation oncologist, professor, and chief medical officer at Alpha Tau Medical in Israel, pointed out that unlike many other cancers, pancreatic cancer lacks effective early screening tools, leaving patients with few treatment options by the time they receive a diagnosis.

The Connection Between Mind and Body

This study underscores the profound connection between mental and physical health as it pertains to cancer development, according to Dr. Den.

He emphasized that stress and its related pathways can accelerate the progression of disease, while obesity can adversely affect a patient’s treatment response.

Furthermore, Dr. Den added that the evidence suggests that stress and obesity may worsen pancreatic cancer outcomes, leading to crucial implications for both preventive strategies and treatment protocols.

Healthy Lifestyle Choices

To combat cancer risks, maintaining a heart-healthy diet and practicing moderation in eating habits are essential. Dr. Den stressed that these measures are vital not only for preventing cancer but also for overall well-being.

He also highlighted the importance of regular exercise in managing both obesity and stress levels. Engaging in physical activity is beneficial for one’s physical health while providing an excellent method to mitigate stress.

Additionally, Dr. Den pointed out that mindfulness techniques can play a significant role in reducing cancer risk. Spending time outdoors, for instance, can enhance both mental and physical health, encouraging patients to remain active and connected to nature.

Current Advances and Challenges in Treatment

Despite the gravity of pancreatic cancer, Dr. Den noted that there have been some advancements in chemotherapy and surgical techniques. However, he also indicated that a major breakthrough in treatment has yet to occur.

While immunotherapies have revolutionized treatment for other types of cancer, they have not shown the same effectiveness for pancreatic cancer. The key challenge continues to be finding solutions for patients unsuitable for surgery, as surgery remains the most effective form of treatment.

Call for Further Research

The research team at UCLA aims to deepen the understanding of how stress and obesity synergistically influence the risk of developing pancreatic cancer. As the study highlights the urgent need for further investigation, it may pave the way for innovative treatment approaches.
