Roundup and Cancer: Analyzing the Link and Recent Legal Developments

Roundup, a popular herbicide containing glyphosate, has been at the center of a heated controversy due to its potential link to cancer. Over the past few years, numerous legal cases have emerged, alleging that Roundup exposure contributed to the development of various types of cancer.

According to Forbes, as of May 2022, Monsanto, now owned by Bayer, has reached settlements in excess of 100,000 Roundup lawsuits, amounting to approximately $11 billion. However, there are still around 30,000 pending lawsuits, including 4,000 cases consolidated under multidistrict litigation (MDL) in California.

According to legal experts specializing in Roundup cases, the average Roundup lawsuit payout and settlement amounts in these cases could range from $5,000 to $200,000 or more, reflecting the varying circumstances and severity of the issues.

In this article, we will delve into the scientific evidence behind the Roundup-cancer connection and explore the latest legal developments surrounding the issue.

The Glyphosate-Cancer Debate

Glyphosate, the active ingredient in Roundup, is a broad-spectrum herbicide widely used around the world to control unwanted vegetation. Developed by Monsanto (now owned by Bayer), Roundup has become one of the most extensively used herbicides in agricultural and non-agricultural settings.

The potential link between glyphosate and cancer has been a topic of intense scientific research and public debate. According to TorHoerman Law, in 2015, the International Agency for Research on Cancer (IARC) designated glyphosate as a substance with a high probability of causing cancer in humans.

This classification was primarily based on studies showing an association between glyphosate exposure and an increased risk of non-Hodgkin lymphoma (NHL).

Scientific Studies and Conflicting Findings

Multiple epidemiological studies have examined the potential relationship between glyphosate exposure and cancer, with a specific focus on non-Hodgkin lymphoma (NHL).

In a noteworthy study conducted in 2019 by researchers at the University of Washington, it was concluded that the use of glyphosate increases the risk of non-Hodgkin lymphoma by 41 percent.

The study, published in the scientific journal Mutation Research, analyzed human epidemiological studies and found compelling evidence suggesting a connection between exposures to glyphosate-based herbicides and an elevated risk of non-Hodgkin lymphoma.

This research adds to the body of evidence surrounding the potential health risks associated with glyphosate, specifically in relation to non-Hodgkin lymphoma.

However, it is important to note that scientific studies in this area have yielded conflicting results. For example, regulatory agencies like the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA) have thoroughly examined glyphosate and determined that when used as instructed, it is unlikely to cause cancer in humans.

Therefore, additional research is necessary to achieve a more comprehensive understanding of the potential connection between glyphosate exposure and cancer.

Roundup Lawsuits and Legal Developments

The Roundup controversy has led to an influx of lawsuits against Monsanto and Bayer, with plaintiffs claiming that Roundup exposure caused their cancer and that the companies failed to warn about the potential risks.

In August 2018, a landmark case resulted in a jury verdict awarding a significant amount of $289 million in damages to a groundskeeper who claimed that his terminal cancer was caused by Roundup. Subsequently, many more cases followed, leading to substantial legal and financial implications for Bayer.

Settlements and Future Implications

In recent years, Bayer has been engaged in settlement negotiations to resolve a substantial portion of the Roundup lawsuits. These settlements aim to compensate those who have been affected by alleged Roundup-related cancers. However, the outcome and scope of these settlements are still evolving, as more cases are being brought to court.

Regulatory Responses and Public Perception

The Roundup controversy has also spurred discussions about the role of regulatory agencies and their evaluation of glyphosate. While some argue for more stringent regulations or even an outright ban, others contend that the scientific evidence does not conclusively establish a causal link between Roundup and cancer.

The public perception of Roundup has shifted, and consumers increasingly demand alternatives and greater transparency regarding the potential risks associated with the herbicide.


The debate surrounding Roundup’s potential link to cancer continues to be complex and contentious. The scientific research conducted so far has yielded conflicting results, and regulatory agencies differ in their conclusions.

The legal landscape has seen significant developments, with lawsuits against Monsanto and Bayer resulting in substantial settlements. As the Roundup saga unfolds, it is crucial to stay informed about the latest scientific studies, legal outcomes, and regulatory decisions to fully grasp the implications of Roundup’s alleged association with cancer.
