Study Links Accelerated Aging to Early Onset Cancer in Younger Generations

A recent study presented at the American Association for Cancer Research Annual Meeting 2024 suggests that accelerated biological aging may be contributing to the rise in early onset cancers among individuals under the age of 55. Researchers from Washington University in St. Louis analyzed data from the UK Biobank and found that those born after 1965 had a higher likelihood of experiencing accelerated aging compared to previous generations.

The study indicates that common pathways such as chronic inflammation and cellular senescence could link accelerated aging to the development of early onset cancers, particularly in the lung, gastrointestinal system, and uterus. While the exact factors contributing to accelerated aging were not identified, experts have suggested potential influences such as increased air travel, more exposure to radiation, and the presence of 'forever chemicals' like PFAS.

According to the study, each standard deviation increase in accelerated aging was associated with a 42% increased risk of early onset lung cancer, a 22% increased risk of early onset gastrointestinal cancer, and a 36% increased risk of early onset uterine cancer. Accelerated aging was also linked to a 16% increased risk of late onset gastrointestinal cancer and a 23% increased risk of late onset uterine cancer.

Why this matters: The findings highlight the importance of understanding the underlying causes of accelerated aging and its potential impact on cancer development in younger generations. Identifying the environmental and lifestyle factors contributing to this trend could lead to new strategies for cancer prevention and early detection.

Researchers highlight that lifestyle factors like smoking, poor diet, and lack of exercise account for 90% of cancers, and addressing the causes of accelerated aging may help reduce cancer risk. They also suggest that interventions to slow biological aging could be a new avenue for cancer prevention, and screening efforts tailored to younger individuals with signs of accelerated aging could help detect cancers early.

Dr. Patricia LoRusso, the new president of the American Association for Cancer Research, stressed the need to advocate for increased funding to support cancer research and education. "More research is needed to fully understand the implications of accelerated biological aging and its impact on early onset cancer development," LoRusso said. "By identifying the environmental triggers driving this trend, we can work towards developing targeted prevention and screening strategies to reduce cancer burden in younger generations."

Key Takeaways

  • Accelerated aging may contribute to rise in early-onset cancers under 55.
  • Chronic inflammation and cellular senescence link aging to lung, GI, uterine cancers.
  • Each SD increase in accelerated aging raises early-onset cancer risk by 22-42%.
  • Lifestyle factors account for 90% of cancers; interventions to slow aging needed.
  • More research required to understand environmental triggers of accelerated aging.
