Roundup Diffuse Large B-Cell Lymphoma Lawsuit | 2026 Latest Updates

Roundup, the glyphosate-based weedkiller made by Monsanto, is the subject of lawsuits from people who developed non-Hodgkin lymphoma, including diffuse large B-cell lymphoma (DLBCL). Plaintiffs allege Roundup caused their cancer, and Monsanto denies the claims. The cases sit in federal MDL No. 2741, in state courts and in a proposed class settlement worth up to $7.25 billion. The settlement names DLBCL as a covered type and awaits final approval. The Supreme Court ruled on June 25, 2026 that federal law blocks a state-law claim that Roundup needed a cancer warning on its label.

March 20, 2015: IARC Classifies Glyphosate as Probably Carcinogenic

The International Agency for Research on Cancer announced that a Working Group of 17 experts from 11 countries classified glyphosate as “probably carcinogenic to humans” (Group 2A) [11]. The Working Group met March 3 to 10, 2015. It based the classification on “limited” evidence in humans, “sufficient” evidence in experimental animals and “strong” evidence for genotoxicity. The human evidence concerned non-Hodgkin lymphoma.

What Is Diffuse Large B-Cell Lymphoma?

According to the National Cancer Institute (NCI), diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. It grows quickly in the lymph nodes, and other organs are often also affected [12]. The California Court of Appeal’s Pilliod opinion calls DLBCL “a common type of non-Hodgkin’s lymphoma” that “is considered an aggressive cancer.”

Who May Be Affected?

People diagnosed with DLBCL may fall within the proposed class settlement. They need U.S. contact with Roundup Products before February 17, 2026, and must have been a U.S. citizen or lived in the U.S. on March 4, 2026. The official settlement FAQs name DLBCL as a covered condition [13]. The List of NHL Subtypes includes “Diffuse large B-cell lymphoma (DLBCL), NOS” and other variants [14]. Hodgkin’s lymphoma and multiple myeloma are not covered. The settlement site separates Occupational Claimants from Residential Claimants. Occupational Claimants need documents such as employment, payroll or tax records. People who opted out by June 4, 2026 keep the right to file their own lawsuit. Someone with a claim pending in MDL No. 2741 on February 17, 2026 must ask to be included and dismiss that claim. In Pilliod, both plaintiffs had sprayed Roundup on four residential properties, starting in 1982. Only an individual legal review can say whether a claim applies to you. Our Roundup lawsuit overview explains the wider litigation.

Reported Injuries or Damages

Plaintiffs allege that Roundup, particularly its active ingredient glyphosate, caused their non-Hodgkin lymphoma. Monsanto denies that Roundup causes NHL and denies any wrongdoing. NCI says DLBCL signs may include fever, drenching night sweats and weight loss. In the Pilliod record, Alva Pilliod’s stage IV DLBCL appeared in his bones. Alberta Pilliod’s appeared in her central nervous system. The IARC Monographs Volume 112 summary says glyphosate “also caused DNA and chromosomal damage in human cells” [15]. EPA’s glyphosate page says EPA concluded glyphosate is “not likely to be carcinogenic to humans” [16]. The Agricultural Health Study followed 54,251 pesticide applicators. Andreotti and colleagues found no association with non-Hodgkin lymphoma or its subtypes [17]. A 2019 meta-analysis by Zhang and colleagues reported a meta-relative risk of 1.41 for NHL as a group, not DLBCL alone, in the highest exposure groups [18].

Evidence to Preserve

Keep any record that shows the diagnosis and your Roundup use. Store the originals safely. Do not throw away product containers or old paperwork, even if a case seems far off. Useful items include:

• A pathology report that names the lymphoma type, and the date of diagnosis.
• Treatment records and other medical records from your doctors, clinics and hospitals.
• Receipts, photos and containers of the Roundup product, with notes on when, where and how you used it.
• Employment, payroll, business license or tax records that show work with the product. The settlement site lists these as proof for occupational claimants.
• Notes on the dates of your first and last exposure to the product.
• Emails, texts and letters that mention the product, how you used it or your diagnosis.

Filing Deadlines

Filing deadlines for a Roundup injury claim come from state law. They depend on where you live and when your exposure, illness and diagnosis happened. Some states start the clock at diagnosis. Missing a deadline can end a claim even when the facts are strong, so talk to a lawyer promptly. The class settlement runs on its own dates. People diagnosed with NHL as of March 4, 2026 register within 180 days after final approval and file a claim within 180 days after any appeals end.

Potential Compensation

Damages in Roundup cases can include medical bills, lost income, and pain and suffering. Settlement tiers depend on exposure type, age and NHL type. The settlement website says eligible people “Could Receive $6,000 to $165,000+”. On July 20, 2020, the Court of Appeal cut the Johnson v. Monsanto judgment to $10,253,209.32 in compensatory and $10,253,209.32 in punitive damages [19]. Johnson’s cancer is not stated as DLBCL in the opinion. Compensation amounts vary by case. Past results do not guarantee future outcomes. Potential compensation in the class settlement is paid by tier.

Frequently Asked Questions

Can Roundup Cause Diffuse Large B-Cell Lymphoma?

Whether Roundup can cause diffuse large B-cell lymphoma is disputed. EPA says its glyphosate finding differs from IARC’s classification. EPA assesses risk under expected real-world exposures, while IARC asks whether a chemical can cause cancer under any conditions.

Is Diffuse Large B-Cell Lymphoma Covered by the Roundup Settlement?

Yes, the Roundup class settlement covers diffuse large B-cell lymphoma by name. Its FAQs list it with follicular lymphoma, hairy cell leukemia, aggressive NK-cell leukemia and chronic lymphocytic leukemia. BrownGreer PLC, the administrator, answers questions at 1-888-403-8201.

How Much Is the Roundup Settlement for Diffuse Large B-Cell Lymphoma?

The Roundup settlement does not set one amount for diffuse large B-cell lymphoma. Awards depend on nine tiers. An actual award can range from 80% to 120% of the tier average. The settlement also includes a $1 billion security fund.

Have Juries Found That Roundup Caused Lymphoma?

Juries have returned verdicts for plaintiffs who said Roundup caused their lymphoma, including Edwin Hardeman and the Pilliods. Monsanto disputes the Hardeman verdict. A Missouri jury also awarded John Durnell $1.25 million after a 9-day trial. The Supreme Court reversed that judgment.

What Did the Supreme Court Decide in the Roundup Durnell Case?

The Supreme Court decided in the Roundup Durnell case that FIFRA preempts John Durnell’s claim. Justice Jackson dissented, joined by Justice Gorsuch. The Solicitor General argued as amicus curiae, and review was limited to label-based failure-to-warn claims.

How Is Diffuse Large B-Cell Lymphoma Treated?

Treatment of diffuse large B-cell lymphoma is decided by the patient’s doctors. NCI says treatment of aggressive stage II, III or IV non-Hodgkin lymphoma may include rituximab with combination chemotherapy. Options for relapsed or refractory DLBCL include tafasitamab plus lenalidomide.
