Millennials are experiencing a concerning trend: an increased risk of cancer at younger ages. Scientists now believe that environmental toxins and exposure to carcinogens may be the main culprits.
For decades, researchers have focused on genetics and lifestyle choices as primary causes of cancer. However, recent studies suggest that environmental factors play a significant role in the development of cancer in young people.
Gary Patti’s team at Washington University School of Medicine is studying how different chemicals affect zebrafish to understand potential human health risks. They’re particularly interested in microplastics and their impact on DNA damage and inflammation.
Ultra-processed foods, which account for over half of daily calorie intake, have also been linked to increased cancer risk. A study published in 2023 found that heavy consumption of ultra-processed foods was associated with a significantly elevated risk of developing certain cancers.
Disruptions to the body’s natural circadian rhythm, caused by late-night work and constant screen time, can also lead to chronic inflammation and increase cancer risk. Some researchers have linked this to the development of breast, colorectal, lung, liver, and pancreatic cancers.
The Centers for Disease Control and Prevention estimate that 97% of Americans have some level of toxic “forever chemicals” in their blood, which are known to persist in the environment and human bodies. This exposure is a concern as it can increase cancer risk.
Researchers are working to understand how these environmental toxins interact with the body’s biology and identify potential testable hypotheses for preventing or treating cancer.
