People diagnosed with colorectal cancer before age 50 show different DNA methylation patterns linked to picloram herbicide exposure compared to those diagnosed at age 70 or older, suggesting a possible environmental association with earlier disease onset.

People exposed to the herbicide picloram have a higher statistical likelihood of developing colorectal cancer before age 50 compared to those who develop it after age 70, based on patterns of DNA methylation observed in patient samples.

Higher use of the herbicide picloram in a geographic area is linked to higher rates of early-onset colorectal cancer, based on molecular changes in tumor tissue and population data adjusted for other factors.

People exposed to the herbicide picloram may show distinct patterns of DNA methylation in colorectal tumors that develop at an early age.

In U.S. counties where more picloram pesticide is used, there is a higher rate of colorectal cancer diagnosed in people under 50, even when accounting for income, education, and exposure to other pesticides.

People who develop colorectal cancer at a younger age show different DNA methylation patterns than those who develop it later in life, suggesting that environmental factors may play a larger role in cancer development among younger people.
