Roundup and Non-Hodgkin Lymphoma
Last updated: June 9, 2026
Non-Hodgkin lymphoma is the illness at the center of Roundup and glyphosate litigation. It is the condition most plaintiffs allege, and it is the focus of the scientific debate over whether long-term glyphosate exposure raises cancer risk. This page explains what non-Hodgkin lymphoma is, what the research and the alleged link involve, and why diagnosis, exposure history, and timing matter so much in these cases.

- Non-Hodgkin lymphoma is the condition most often alleged in Roundup litigation.
- The alleged link rests largely on the IARC classification and certain epidemiological studies; other regulators disagree.
- Cases commonly involve heavy, long-term exposure among agricultural and grounds workers.
- Diagnosis subtype, exposure history, and timing are typically central to how a claim is evaluated.
What Non-Hodgkin Lymphoma Is
Non-Hodgkin lymphoma (NHL) is a group of cancers that begin in the lymphatic system, the network of vessels and nodes that is part of the body's immune system. It includes many subtypes, such as diffuse large B-cell lymphoma and follicular lymphoma. Early signs can be non-specific, including swollen lymph nodes, fatigue, unexplained weight loss, fever, and night sweats. Because those signs overlap with many other conditions, diagnosis requires medical testing.
The Alleged Link to Glyphosate
The connection people research traces back largely to the 2015 decision by the International Agency for Research on Cancer (IARC) to classify glyphosate as "probably carcinogenic to humans," a conclusion that drew in part on studies of agricultural workers and non-Hodgkin lymphoma. Other regulators, including the U.S. EPA, have reviewed the evidence and not reached the same conclusion. This unresolved scientific disagreement is the backdrop for the litigation. For more on that split, see Is Roundup Dangerous? and the regulatory analysis in Glyphosate Lawsuits: EPA, Bayer and the Supreme Court.
Why Exposure History and Timing Matter
The cases that move through the courts typically involve heavy, repeated, long-term exposure rather than occasional home use — agricultural workers, commercial landscapers, and groundskeepers who handled the product regularly over years. Because cancers like NHL can develop long after exposure, the timeline between use and diagnosis, the products used, and the documentation of that history often become central questions. None of those facts decide a claim on their own, but together they shape how a case is evaluated.
How This Fits Into the Litigation
Roundup non-Hodgkin lymphoma claims generally allege failure to warn and product liability — that manufacturers did not adequately disclose alleged cancer risks.

If You Have Been Diagnosed
A non-Hodgkin lymphoma diagnosis is first and foremost a medical matter to be managed with your care team. If you also have a history of long-term glyphosate or Roundup exposure and are wondering whether your situation fits into the litigation, the documentation discussed above — product use, work history, and diagnosis records — is the kind of information a case review would look at.
