If you use Roundup weed killer on a frequent basis, you could be at an increased risk of developing cancer. Researchers worldwide have conducted studies on a chemical called glyphosate that’s found in Roundup. Their findings suggest glyphosate is associated with an increased cancer risk.

This volume of research recently prompted the World Health Organization (WHO)’s International Agency for Research on Cancer (IARC) to call glyphosate out as a “probable human carcinogen.” This means the organization finds the chemical likely to be dangerous and to cause cancer.

What Research Says About a Link Between Glyphosate and Cancer

For decades, safety organizations have wavered on their stances on how safe glyphosate really is. The substance first found use as a pesticide in the United States in the 1970s. By the 1980s, the Environmental Protection Agency (EPA) warned that glyphosate could be dangerous.

However, this warning was short-lived. In the early 1990s, the EPA had changed its mind, citing a “lack of convincing evidence” that the chemical caused cancer. Workers in the agriculture industry continue to use glyphosate as an herbicide.

Since then, a number of studies conducted across the globe have suggested that the EPA’s original fear was correct. A Canadian study published in 2001 first showed that the number of glyphosate exposures a person has determines how much their cancer risk increases.
