Deadly Cancer Type Linked to Obesity and High Stress Levels
Healthy diet, exercise and mindfulness could reduce pancreatic cancer risk, study finds
Obesity and stress could magnify the risk of one of the most aggressive types of cancer, a new study suggests.
Researchers at University of California Los Angeles (UCLA) found that stress-related neurotransmitters and obesity-related hormones activated CREB (cyclic AMP response element-binding protein), which was shown to promote the growth of cancer cells in the pancreas.
In the study, mice that ate a high-fat diet were more likely to develop precancerous lesions. When stress levels were also raised through social isolation, the lesions grew even more.
The stress-related cancer risk was more pronounced in female mice.
Based on these findings, the researchers suggested exploring the use of existing medications to reduce the risk of obesity- and stress-related cancers.
"Since β-adrenergic receptors play a crucial role in stress-related cancer growth, commonly used beta-blockers, which are drugs prescribed for high blood pressure, could be repurposed to help mitigate these effects," a press release stated.
Pancreatic cancer is one of the deadliest types in the U.S., with a five-year survival rate of just 13%.
