You trusted Roundup to keep your lawn weed-free but growing evidence suggests that what kept your yard clean could have jeopardized your health. Researchers, cancer patients, and thousands of lawsuits now point to a potential link between glyphosate (the active ingredient in Roundup) and serious cancers, most notably non-Hodgkin lymphoma.
If you think Roundup might have hurt you, you owe it to yourself to learn the facts.
What is Glyphosate?
Glyphosate is a broad-spectrum herbicide originally developed to kill weeds without harming grass making it popular for lawn and garden care nationwide. But decades of research have raised alarms that glyphosate may actively damage human cells, disrupt DNA, and increase the risk of cancer.
How People Are Exposed
- Residential Use: Spraying on lawns, gardens, or home landscapes
- Occupational Exposure: Farmers, landscapers, groundskeepers, and agricultural workers who apply glyphosate-based products regularly
- Environmental Exposure: Drift from nearby spraying, contaminated soil or run-off, and ingestion of treated produce
Health Risks Backed by Science
Multiple international health organizations, including the International Agency for Research on Cancer (IARC), have linked glyphosate to non-Hodgkin lymphoma (NHL) and other serious conditions. This mounting evidence has led to thousands of lawsuits worldwide.
Is Roundup Banned in the US?
Bayer (which acquired Roundup when it bought Monsanto in 2018) has consistently defended glyphosate’s safety profile. However, in the wake of the litigation, the company announced in 2021 that it would stop selling glyphosate-based Roundup for residential use in 2023.
Though consumer versions of Roundup no longer contain glyphosate, there is no federal ban on the herbicide for commercial and agricultural use in the USA. This means people may still be exposed to glyphosate in a variety of ways, including by consuming produce treated with the product.
It’s crucial to note that, while Roundup containing glyphosate is no longer sold for residential use, products purchased prior to 2023 may still contain the chemical. If you use Roundup and are unsure when it was purchased, it’s important to check the label before applying it to your lawn or garden.
The Dangers of Glyphosate Exposure
Glyphosate-based Roundup weed killer has been linked to serious health problems. These include:
- Several forms of cancer
- Infertility
- Liver and kidney problems
- Gut microbiome disruption
Glyphosate exposure can happen in a variety of ways to those who:
- Used a glyphosate-based weed killer (like Roundup) on their lawns or gardens
- Worked with or around glyphosate herbicides
- Live in a rural area where glyphosate is used
- Consume fruits, vegetables, or other produce treated with Roundup
What Cancers Are Included in the Roundup Lawsuit?
Countless records collected in the Roundup Lawsuit claim users exposed to the Roundup weed killer have been diagnosed with various types of cancers. The primary health condition associated with glyphosate exposure has been non-Hodgkin lymphoma. Consumers may wonder what other cancers are included in the Roundup Lawsuit. The list includes the following:
- Anaplastic large cell lymphoma
- B-lymphoblastic lymphoma
- Burkitt lymphoma
- Chronic lymphocytic leukemia
- Cutaneous T-cell lymphoma
- Diffuse large B-cell lymphoma
- Extranodal marginal zone B-cell lymphoma, mucosa-associated lymphoid tissue
- Follicular lymphoma and hairy cell leukemia
- Large granular lymphocytic leukemia
- Lymphoplasmacytic lymphoma (Waldenstrom Macroglobulinemia)
- Mantle cell lymphoma
- Marginal zone B-cell lymphomas
- Mycosis fungoides
- Nodal marginal zone B-cell lymphoma
- Peripheral T-cell lymphomas
- Primary central nervous system lymphoma
- Sezary syndrome
- Small lymphocytic lymphoma
- Splenic marginal zone B-cell lymphoma
Roundup: A History of Controversy
Glyphosate has a long record of public distrust. The chemical was discovered by a Monsanto scientist and entered the consumer market in the 1970s. By the 1980s, Monsanto became aware of its link to cancer—but failed to warn consumers. Since then, a battle has raged among national and worldwide health organizations regarding glyphosate’s safety.
Organizations that recognize the chemical’s dangers include:
- The World Health Organization’s International Agency for Research on Cancer (IARC)
- The California Office of Environmental Health Hazard Assessment (OEHHA)
- The U.S. Agency for Toxic Substances and Disease Registry (ATSDR)
However, some agencies deny any link between glyphosate and cancer:
- The U.S. Environmental Protection Agency (EPA)
- The European Food Safety Authority (EFSA)
- The Australian Pesticides and Veterinary Medicines Authority (APVMA)
In June of 2022, the Ninth Circuit ordered the EPA to re-evaluate glyphosate’s approval, ruling that the organization failed to properly evaluate the chemical’s cancer risk. This action further heightened national attention on the potential dangers of glyphosate-based pesticides.
Though the EPA’s final review on glyphosate’s safety isn’t expected until 2026, the organization currently maintains its stance that glyphosate is unlikely to cause cancer in humans.
Recently, internal communications were released by Bayer during the Roundup lawsuits, indicating that Monsanto staff may have been aware of the herbicide’s potential dangers. Disturbingly, these documents seem to show that the company intentionally withheld this information from the public.
Is the New Roundup Safe?
Residential Roundup no longer contains glyphosate—but is it harmless to human health? While some believe it poses a lower risk of toxicity than glyphosate-based herbicides, critics worry that Bayer traded one toxic chemical for a concoction of even more harmful ones with its new formulation.
New residential Roundup contains four active ingredients: diquat dibromide, fluazifop-P-butyl, triclopyr, and imazapic. These chemicals are linked to kidney and liver damage, as well as reproductive harm. Studies also show they are even more damaging to the environment than glyphosate, harming bees, earthworms, birds, and aquatic life.
Concern about new Roundup products aside, the formulation change makes one point clear. The growing number of lawsuits—and the bravery of the plaintiffs behind them—prove that individuals can enact change and force powerful corporations like Bayer and Monsanto to take accountability.
The Future of the Roundup Lawsuit
Monsanto and Bayer have entered into nearly 100,000 settlement agreements for Roundup claims. To date, Bayer has paid out around $11 billion to those who developed health issues related to exposure to the glyphosate weed killer.
Despite this progress, around 67,000 Roundup claims remain pending. Most of these cases are now in state courts. However, about 4,400 cases continue pending in the federal MDL (multidistrict litigation).
Different states have shown varying degrees of support for plaintiffs. Georgia and North Dakota recently backed pesticide manufacturers by passing laws shielding them from certain types of future lawsuits (existing cases are not affected). Meanwhile, a Missouri court upheld a $1.25 million verdict against Bayer in May 2025 in favor of a plaintiff diagnosed with non-Hodgkin lymphoma.
As of June 30, 2025, the US Supreme Court is still considering whether to hear Bayer’s appeal of the Missouri decision. The outcome will significantly shape how state and federal courts handle pending—and future—Roundup lawsuits.
What Can You Do if You Believe You Have Been Harmed by Roundup?
If you were harmed by Roundup, you may be considering joining the class action lawsuit. Doing so helps to ensure that powerful companies like Monsanto and Bayer are held responsible for their actions. Taking part in the litigation also gives you a chance to hold these corporations accountable for the injuries you sustained.
If you developed any of the above-mentioned cancers or acquired another health condition you believe is linked to Roundup exposure, you could be owed compensation.
