You might be surprised to hear that certain pesticides could raise your risk of getting prostate cancer. A team from Stanford University looked into this over many years, as prostate cancer takes a long time to develop. They found that 22 specific pesticides were linked to a higher chance of getting this disease.

Scientists checked how much and which pesticides were used in counties across the U. S. from 1997 to 2001. They compared this to prostate cancer rates from 2016 to 2020. The delay between exposure to a harmful substance and cancer growth is around 10 to 18 years, so they needed to look back in time.

Among these 22 pesticides, three were already known to be linked to prostate cancer. One of them, 2-4-D, is very commonly used. But there were also 19 others, including herbicides, fungicides, insecticides, and a soil fumigant.

Four of these pesticides were especially dangerous. They were linked to both getting prostate cancer and dying from it. These included trifluralin, cloransulam-methyl, diflufenzopyr, and an insecticide called thiamethoxam. Out of these, only trifluralin is considered a possible human carcinogen by the Environmental Protection Agency (EPA). The others have been deemed not likely to cause cancer.

The study shows that understanding the environment, like pesticide use, can help us figure out why prostate cancer rates vary across the U. S. This could help us find ways to lower the number of men affected by this disease.
