Roundup Weedkiller Has Been Linked to a Type of Blood Cancer — Over $10 Billion Has Been Paid Out

The short version: Roundup is one of the most widely used weedkillers in the world. The main chemical in it is called glyphosate. In 2015, the World Health Organization’s cancer research arm said glyphosate is a “probable human carcinogen” — meaning it probably causes cancer in people. Tens of thousands of people who used Roundup regularly and later developed non-Hodgkin lymphoma, a type of blood cancer, have received money from Bayer. New cases are still being accepted. If this sounds like your situation, checking if you qualify is free and takes two minutes.

What Is Glyphosate, and Why Does It Matter?

Glyphosate is the active chemical in Roundup that kills weeds. It was developed by Monsanto, which is now owned by the German company Bayer. Roundup has been sold since the 1970s, and for decades it was marketed as one of the safest herbicides on the market.

In 2015, that changed. The International Agency for Research on Cancer (IARC), which is a branch of the World Health Organization (WHO), published a major review of the science and formally classified glyphosate as a “Group 2A” substance — meaning it is a “probable human carcinogen.” This was based on evidence that glyphosate caused cancer in lab animals, and on studies showing higher rates of certain cancers among people who had been exposed to it.

Bayer and its predecessor Monsanto have contested this conclusion. But the IARC’s classification opened the door to legal action, and what followed was one of the largest waves of personal injury lawsuits in U.S. history. Tens of thousands of people who used Roundup regularly and were later diagnosed with non-Hodgkin lymphoma sued Bayer in federal court.

What Is Non-Hodgkin Lymphoma?

Non-Hodgkin lymphoma (NHL) is a type of blood cancer that starts in the lymphatic system — the network of vessels and organs that help your body fight infection. Your lymphatic system includes your lymph nodes (the small glands you might feel in your neck or armpits when you’re sick), your spleen, and your bone marrow.

When you have NHL, abnormal blood cells grow out of control in the lymph system. Symptoms can include swollen lymph nodes, extreme tiredness, fever, night sweats, unexplained weight loss, and belly pain or swelling. NHL is treated with chemotherapy, radiation, and sometimes a bone marrow transplant.

There are many types of NHL. The most common kind linked to glyphosate exposure in the lawsuits is called diffuse large B-cell lymphoma (DLBCL), but other types have also been included in the litigation.

Who May Qualify

You may qualify if the following apply to you:

• You used Roundup — or other glyphosate-based weedkillers — regularly. “Regularly” generally means at least once a week for a year or more. Farmers, gardeners, landscapers, nursery workers, groundskeepers, and people who maintained their own lawns are among those who have filed.
• You were later diagnosed with non-Hodgkin lymphoma or a related blood cancer, such as hairy cell leukemia or chronic lymphocytic leukemia, which have also appeared in the lawsuits.
• Your diagnosis came after your Roundup exposure — not before you started using it.

You do not need to have used Roundup professionally. Many people who qualify used it at home on their lawns or in their gardens over many years. You also do not need to have kept any containers or receipts. What matters is your memory of how often you used it and roughly when.

The $10.9 Billion in Payments

In June 2020, Bayer announced it would pay more than $10.9 billion to settle approximately 100,000 Roundup lawsuits. This resolved the bulk of the cases that had been filed, but it did not close the door on new cases. Individual lawsuits are still being filed and reviewed, and in early 2026 a proposed national class settlement to resolve future cases was receiving attention in federal court.

The cases are grouped together in federal court in California under MDL No. 2741 (U.S. District Court, Northern District of California, Judge Vince Chhabria). Some individual cases that could not be settled have gone to trial, with plaintiffs winning in some instances. Bayer has also appealed certain verdicts.

We will not quote you a specific dollar amount. What any individual case may result in depends entirely on each person’s specific diagnosis, medical history, and how long and heavily they used Roundup. Those factors are unique to every person.

Why Deadlines Matter

Every state has its own rule about how long you have to file a lawsuit after discovering you were harmed. These deadlines — sometimes called statutes of limitations — vary by state and by the specific circumstances of your case. In some states the window is as short as one year from when you first connected your cancer to your Roundup use. In others it may be two to three years.

Here is what matters: the clock is already running. If you used Roundup for years and have been diagnosed with NHL or a related cancer, your window to file may already be closing. The case check is free. Checking takes two minutes. If you qualify, someone will reach out within one week. If you do not qualify, you have lost nothing.

Common Questions

I used Roundup at home on my lawn. Does that count?

Potentially, yes. Many people who have received money in these cases are not farmers or professionals — they are homeowners who sprayed Roundup on their yards and gardens over many years. What matters is how often and for how long you used it. Include those details in the form.

I don’t remember exactly which brand I used — could it have been a different glyphosate weedkiller?

There are many generic and store-brand glyphosate weedkillers on the market, made by companies other than Bayer/Monsanto. Some of those cases are also being evaluated. Include whatever you remember about the product you used in the form and let the review team assess it.

I live in a state other than California. Does this apply to me?

Yes. The federal MDL is in California, but cases come from all over the country. You can qualify from any state. Deadlines vary by state, so check sooner rather than later.

Does it cost anything?

The case check is completely free. If you sign up with a law firm, you pay nothing unless your case recovers money. Attorney fees come only from what is won for you — never out of your pocket beforehand.

What if I used Roundup years ago but was diagnosed recently?

That is common in these cases. The cancer can develop years after the exposure. Many people diagnosed in recent years used Roundup heavily throughout the 1990s, 2000s, and 2010s. Your timeline may still qualify.

Ready to Check If You Qualify?

If you used Roundup or another glyphosate weedkiller regularly for a year or more — at work or at home — and were later diagnosed with non-Hodgkin lymphoma or a related blood cancer, you may be owed money. The check is free, takes two minutes, and costs you nothing no matter what.
