Brain aging may accelerate after cancer treatment, study suggests
A study suggests that surviving cancer during childhood or young adulthood may accelerate biological aging, leading to cognitive issues later in life.
Recent research from the University of Rochester Medical Center indicates that life-saving treatments for cancer, such as chemotherapy and radiation, might accelerate biological aging in survivors who were treated as children or young adults. The study specifically aimed to assess whether this acceleration in biological age correlates with cognitive impairments in memory, focus, and learning, which are critical areas of mental function. By analyzing blood samples from over 1,400 long-term cancer survivors, researchers employed epigenetic clocks to evaluate biological age based on cellular damage rather than chronological age.
The findings reveal that biological age can diverge significantly from chronological age, with implications for individuals who have undergone cancer treatment during crucial developmental years. Epigenetic clocks measure the chemical changes on DNA that accumulate due to environmental factors and health conditions. This divergence may be particularly relevant for cognitive functions, as it has been previously established that aging-related biomarkers are linked to neurocognitive decline.
These insights could influence future healthcare strategies for childhood cancer survivors, as they highlight the need for ongoing monitoring and potential interventions aimed at mitigating cognitive decline. Understanding the relationship between cancer treatments and accelerated aging is vital not only for improving the quality of life for cancer survivors but also for integrating these findings into preventative measures and treatment protocols.
