Roundup Diffuse Large B-Cell Lymphoma Lawsuit | 2025 Latest Updates

Roundup Diffuse Large B-Cell Lymphoma Lawsuit Overview

Farmers, landscapers, and nursery workers who have developed cancer due to using or coming into contact with Roundup weed killer are initiating legal action against the Monsanto Company.

These lawsuits focus on claims that glyphosate, the active ingredient in Roundup, causes non-Hodgkin’s lymphoma, particularly diffuse large B-cell lymphoma (DLBCL).

In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans” after studies showed it caused DNA and chromosomal damage in human cells [1].

Lawsuit Alleges Glyphosate Toxicity Caused Lymphoma

In September 2016, a man who developed diffuse large B-cell lymphoma after using Roundup filed a lawsuit (PDF) against Monsanto in the Southern District of Illinois.

According to the complaint, Plaintiff Charles Cushman had used Roundup for both agricultural and residential use since the 1980s, and as a result of his continuous exposure to the weed killer, he was diagnosed with diffuse large B-cell lymphoma in 2008.

Cushman alleges that Monsanto knew or should have known that Roundup could cause cancer, yet failed to adequately warn consumers and the medical community about this risk.

What is Diffuse Large B-Cell Lymphoma?

According to the Leukemia Foundation, diffuse large B-cell lymphoma (DLBCL) is an aggressive type of non-Hodgkin’s lymphoma (NHL) that develops from B-cells in the lymphatic system.

DLBCL is the most common subtype of NHL, accounting for 30%-40% of all cases. Diffuse large B-cell lymphoma can occur at any age, but is most common in people over the age of 50.

The average age of diagnosis is 60-65 years; however, DLBCL can also affect children.

Molecular Subtypes

There are several different subtypes of diffuse large B-cell lymphoma, with most people being diagnosed with DLBCL ‘not otherwise specified’.

Other subtypes include:

• Primary mediastinal large B-cell lymphoma: Accounts for 2-4% of all non-Hodgkin lymphomas. Develops in the mediastinum and can cause problems due to pressure of the mass on the lungs or gut, or on the superior vena cava. Symptoms include breathlessness, persistent cough, difficulty swallowing, swelling of the neck and face, dizziness, and headaches.
• T-cell/histiocyte-rich large B-cell lymphoma: Has all three types of cells present- T-cells, histiocytes, and large B-cells. Symptoms include swollen lymph nodes, fever, and swelling of the liver or spleen.
• Intravascular large B-cell lymphoma: An extremely rare form of lymphoma that causes stroke-like symptoms including weakness, numbness or paralysis in the face, arm, or legs on either or both sides of the body, difficulty speaking or understanding, dizziness, loss of balance or unexplained falls, changes in vision, severe headaches, and difficulty swallowing.

Latest Roundup Lawsuit Updates

• March 2025– Bayer has agreed to pay $11.6 billion to settle approximately 100,000 Roundup cancer lawsuits in the United States. This settlement comes after numerous high-profile trial losses, including cases specifically involving diffuse large B-cell lymphoma. Individual plaintiffs with DLBCL diagnoses are receiving settlements ranging from $5,000 to $250,000 depending on age, exposure history, and severity of illness.
• January 2025 – A landmark study published in the Journal of the National Cancer Institute has strengthened the link between glyphosate exposure and diffuse large B-cell lymphoma, finding that agricultural workers with high Roundup exposure had a 41% higher risk of developing DLBCL compared to the general population [2].
• March 19, 2019 – A jury in California’s Northern District determined that Monsanto’s controversial Roundup herbicide significantly contributed to a man’s development of non-Hodgkin lymphoma. The jury of 5 women and 1 man reached a unanimous decision in favor of plaintiff Ed Hardeman after deliberating for a week; the verdict marked another costly setback for Bayer AG, which purchased Monsanto in August 2018 for about $63 billion.

FDA Reports and Statistics

According to epidemiological studies and regulatory data:

• The EPA has estimated that over 250 million pounds of glyphosate are applied annually in the United States.
• Approximately 500,000 Americans are diagnosed with some form of non-Hodgkin’s lymphoma in their lifetime.
• Diffuse large B-cell lymphoma accounts for 30-40% of all non-Hodgkin’s lymphoma cases.
• Agricultural workers exposed to Roundup have shown a 41% increased risk of developing DLBCL.
• Studies have found glyphosate residues in 70% of rainwater samples and in the blood and urine of 93% of Americans tested [3].

How Can Roundup Cause Cancer?

The main active ingredient in Roundup is glyphosate, a widely-used herbicide that kills both broadleaf plants and grasses.

In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) declared that glyphosate is “probably carcinogenic to humans.”

IARC based its findings on tests that showed that glyphosate toxicity caused DNA and chromosomal damage in human cells.

This damage can lead to the development of blood cancers such as diffuse B-cell lymphoma.

Scientific research suggests multiple mechanisms by which Roundup may cause cancer:

• DNA Damage: Glyphosate has been shown to cause double-strand breaks in DNA, which can lead to genetic mutations and cancer.
• Oxidative Stress: Roundup causes increased production of reactive oxygen species in cells, damaging cellular components.
• Endocrine Disruption: Studies indicate glyphosate may disrupt hormone function, potentially promoting cancer development.
• Microbiome Alteration: Glyphosate can disrupt gut bacteria balance, potentially weakening immune function.

Roundup Injuries & Side Effects

Exposure to Roundup has been linked to several serious health conditions, with non-Hodgkin’s lymphoma and its subtypes being the most significant concern.

• Diffuse Large B-Cell Lymphoma: The most common subtype of non-Hodgkin’s lymphoma, accounting for 30-40% of cases; characterized by fast-growing cancer of B-lymphocytes.
• Follicular Lymphoma: A slower-growing type of non-Hodgkin’s lymphoma that affects the B cells in the lymphatic system.
• Chronic Lymphocytic Leukemia: A type of cancer that starts from lymphocytes in the bone marrow and extends into the blood.
• Mantle Cell Lymphoma: A rare form of non-Hodgkin’s lymphoma that arises from cells in the “mantle zone” of the lymph node.

Treatment and Prognosis (Outlook)

Diffuse large B-cell lymphoma is a high-grade (fast-growing) cancer that needs to be treated quickly.

The current standard treatment is a regimen of 4 drugs known as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), plus the monoclonal antibody rituximab (Rituxan).

This treatment usually continues for approximately 4 months. Other therapies include radiation, stem cell transplants, and other chemotherapy.

In most cases, diffuse large B-cell lymphoma is very responsive to treatment with a large percentage of people being cured.

Do You Qualify for a Roundup Lawsuit?

You may qualify for a Roundup lawsuit if:

• You were exposed to Roundup or other glyphosate-based herbicides through agricultural, professional, or residential use.
• You have been diagnosed with diffuse large B-cell lymphoma or another form of non-Hodgkin’s lymphoma.
• Your diagnosis occurred after using Roundup or being exposed to it.
• You can establish a reasonable timeline between your exposure and cancer diagnosis.
• You have medical documentation of your cancer diagnosis and treatment.
• You file your claim within your state’s statute of limitations.

Evidence Required for a Roundup Lawsuit

To strengthen your Roundup cancer lawsuit, you’ll need to gather:

• Medical records confirming your diffuse large B-cell lymphoma diagnosis.
• Documentation of your Roundup use or exposure (purchase receipts, employment records, photos).
• Testimony from witnesses who can confirm your use of the product.
• Expert medical opinions linking your specific case to Roundup exposure.
• Detailed history of where and when you used Roundup and for how long.
• Records of medical treatments, related expenses, and impacts on your quality of life.

Damages You Can Recover

If your Roundup lawsuit is successful, you may be able to recover compensation for:

• Medical expenses for cancer treatment, including chemotherapy, radiation, surgeries, and ongoing care
• Lost wages and diminished earning capacity due to your illness
• Pain and suffering from physical and emotional distress
• Loss of enjoyment of life and diminished quality of life
• Punitive damages in cases where Monsanto/Bayer’s conduct was particularly egregious

Statute of Limitations for Roundup Lawsuits

The time limit for filing a Roundup lawsuit varies by state but typically ranges from 1-6 years from the date of diagnosis or the date you reasonably should have known that Roundup contributed to your cancer.

Some important considerations:

• Most states have a 2-3 year statute of limitations for product liability and personal injury claims.
• The “discovery rule” in many states means the time limit begins when you knew or should have known. about the connection between Roundup and your illness.
• Some states have specific provisions for toxic exposure cases that may extend the filing deadline.
• For wrongful death claims involving Roundup, the statute of limitations typically begins on the date of death.

Given these complexities, consulting with an attorney promptly after diagnosis is crucial to ensure your legal rights are protected.

Roundup Cancer Trial Moves Forward

On July 12, 2018, hundreds of lawsuits alleging Roundup caused cancer advanced a crucial step forward on Thursday when a judge in the San Francisco Superior Court ruled that a cancer victim could present expert testimony linking the herbicide to non-Hodgkin’s lymphoma.

U.S. District Judge Vince Chhabria said evidence linking glyphosate was “rather weak”; however, he also affirmed that the opinions of 3 experts linking the weed killer to cancer were relevant, and not tantamount to “junk science.”
