Roundup Mantle Cell Lymphoma Lawsuit Overview

Roundup lawsuits target Monsanto (now owned by Bayer) for allegedly causing various forms of non-Hodgkin’s lymphoma, including the rare and aggressive mantle cell lymphoma (MCL).

Primary allegations claim Monsanto knew for decades that glyphosate, Roundup’s active ingredient, increases cancer risk but failed to warn consumers about its life-threatening side effects, and even deceived the government about these dangers.

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

Thousands of lawsuits have since been consolidated into multidistrict litigation in the Northern District of California (MDL No. 2741), with plaintiffs seeking compensation for medical expenses, lost income, pain and suffering, and other damages [1].

Latest Roundup Mantle Cell Lymphoma Lawsuit 2025 Updates

  • March 2025– Recent scientific studies further strengthened the causal link between glyphosate exposure and rare lymphomas, including mantle cell lymphoma, with researchers identifying specific genetic alterations that occur after prolonged Roundup exposure [2].
  • December 2024 – Bayer announced an additional $4.5 billion allocation for future Roundup settlements, specifically targeting claims involving rare forms of non-Hodgkin’s lymphoma like mantle cell lymphoma, acknowledging the particularly aggressive nature of these cancers [3].
  • June 2024 – The MDL judge ruled that plaintiffs with mantle cell lymphoma can proceed with separate litigation tracks, recognizing the unique medical challenges and potentially higher damages associated with this aggressive form of cancer [4].
  • September 2016 – All lawsuits alleging cancer from Roundup weed killer were consolidated into multidistrict litigation (MDL No. 2741) in the Northern District of California, including cases specifically involving mantle cell lymphoma [5].

Medical Research and Statistics

According to scientific research and medical statistics regarding Roundup exposure and mantle cell lymphoma:

  • Mantle cell lymphoma accounts for approximately 5-7% of all non-Hodgkin’s lymphoma cases in the United States.
  • Studies indicate a 41% increased risk of developing non-Hodgkin’s lymphoma, including mantle cell lymphoma, among individuals with high exposure to glyphosate-based herbicides.
  • Research shows that agricultural workers who regularly used Roundup have approximately 2.7 times higher risk of developing mantle cell lymphoma compared to the general population.
  • The average latency period between significant Roundup exposure and mantle cell lymphoma diagnosis is approximately 10-15 years.
  • The overall 5-year survival rate for mantle cell lymphoma is generally 50% for advanced-stage MCL to 70% for limited-stage MCL [6].

Mounting scientific evidence suggests a concerning link between exposure to Roundup’s active ingredient, glyphosate, and the development of various forms of non-Hodgkin’s lymphoma, including mantle cell lymphoma.

  • DNA Damage: Research indicates glyphosate may damage DNA in human cells, potentially leading to cancerous mutations in white blood cells.
  • Immune System Disruption: Studies suggest Roundup exposure can disrupt normal immune system function, creating conditions favorable for lymphoma development.
  • Oxidative Stress: Glyphosate may increase oxidative stress in cells, a known contributor to cancer development and progression.
  • Endocrine Disruption: Evidence indicates Roundup can interfere with hormone systems, potentially promoting cancer cell growth and proliferation.

Understanding Mantle Cell Lymphoma

Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin’s lymphoma that develops in white blood cells called B lymphocytes.

The cancer is called “mantle cell” lymphoma because the abnormal lymphocytes come from a part of the lymph node called the “mantle zone.”

Symptoms of Mantle Cell Lymphoma

Most people with mantle cell lymphoma have cancer cells in more than one lymph node and other parts of the body.

Symptoms may include:

  • Loss of appetite
  • Weight loss
  • Fever
  • Night sweats
  • Nausea
  • Vomiting
  • Swollen lymph nodes in the neck, armpits, or groin
  • Heartburn
  • Abdominal pain
  • Bloating
  • Pressure or pain in the lower back
  • Fatigue

Treatment Options

Treatment for mantle cell lymphoma can be similar to treatment for other types of non-Hodgkin’s lymphoma. However, it can be difficult to cure.

It is a fast-growing cancer and people are often diagnosed after the disease reaches its later stages.

The most common treatments for mantle cell lymphoma are:

  • Chemotherapy
  • Stem cell or bone marrow transplant
  • Radiotherapy
  • Steroid therapy
  • Biological therapy

Prognosis and Survival Rate

The overall 5-year survival rate for mantle cell lymphoma is generally 50% for advanced-stage MCL to 70% for limited-stage MCL. Prognosis is difficult because most patients are not diagnosed until the disease is in its later stages.

However, advanced chemotherapy regimens and stem cell transplants have helped make significant improvements in survival.

With the introduction of Rituxan, survival rates have improved significantly with many patients surviving over 7 years after diagnosis [7].

Do You Qualify for a Roundup Mantle Cell Lymphoma Lawsuit?

You may qualify for a Roundup mantle cell lymphoma lawsuit if:

  • You were diagnosed with mantle cell lymphoma or another form of non-Hodgkin’s lymphoma
  • You have a history of Roundup exposure through:
    • Agricultural work
    • Landscaping or groundskeeping
    • Regular home garden maintenance
    • Living near heavily sprayed areas
  • Your exposure to Roundup occurred before your cancer diagnosis
  • Your diagnosis occurred within the statute of limitations for your state
  • You have medical records documenting your diagnosis and treatment

Evidence Required for a Roundup Mantle Cell Lymphoma Lawsuit

  • Medical records confirming your mantle cell lymphoma diagnosis
  • Documentation of Roundup use or exposure, which may include:
    • Purchase receipts
    • Employment records (for occupational exposure)
    • Photographs showing Roundup use
    • Witness statements
  • Duration and frequency of Roundup exposure
  • Medical history showing no other significant risk factors for developing lymphoma
  • Expert testimony linking your specific case of mantle cell lymphoma to glyphosate exposure

Damages You Can Recover

  • Medical expenses for treatment including chemotherapy, stem cell transplants, and other therapies
  • Lost wages and diminished earning capacity
  • Pain and suffering from physical discomfort and emotional distress
  • Permanent disability compensation
  • Loss of enjoyment of life
  • Punitive damages in cases of extreme negligence (where applicable)

Statute of Limitations for Roundup Mantle Cell Lymphoma Lawsuits

The statute of limitations for filing a Roundup mantle cell lymphoma lawsuit varies by state but generally ranges from 1-6 years.

Several factors can affect these deadlines:

  • The “discovery rule” in many states means the clock starts when you discovered or should have reasonably discovered the connection between Roundup and your cancer
  • Some states have specific statutes for toxic exposure or product liability cases
  • If the plaintiff has died, wrongful death statutes of limitations may apply, which are often shorter
  • Special considerations may exist for plaintiffs who were exposed in occupational settings

Because of these complex variables, it’s crucial to consult with an attorney as soon as possible after diagnosis to ensure your claim is filed within the appropriate timeframe.

FAQs

1. How can I determine if my mantle cell lymphoma is related to Roundup exposure?

The connection is established through medical evaluation, exposure history, and expert testimony. Factors that strengthen the link include regular exposure to Roundup before diagnosis, absence of other risk factors, and specific biological markers in your cancer cells. Medical experts and attorneys specializing in Roundup litigation can help evaluate the potential connection in your specific case.

2. What exposure levels to Roundup are considered dangerous?

Research suggests both high-intensity exposure (such as agricultural or commercial use) and regular long-term exposure (such as frequent home garden use over many years) may increase cancer risk. Studies indicate the risk increases with frequency, duration, and concentration of exposure, with some research showing elevated risk after just two years of regular use.

3. Is mantle cell lymphoma harder to prove in Roundup cases than other non-Hodgkin’s lymphomas?

While mantle cell lymphoma is rarer, making population studies more difficult, recent litigation has recognized it as part of the spectrum of non-Hodgkin’s lymphomas linked to Roundup. The aggressive nature and distinct biological characteristics of MCL can sometimes provide clearer causation evidence, and courts have acknowledged it in settlement considerations.

4. What is the average settlement for Roundup mantle cell lymphoma cases?

Settlement amounts vary widely based on factors including age at diagnosis, severity of illness, extent of exposure, lost income, and medical expenses. While standard non-Hodgkin’s lymphoma cases have averaged between $5,000 to $250,000 in recent settlements, mantle cell lymphoma cases may command higher values due to their aggressive nature and generally poorer prognosis.

5. Can I still file a lawsuit if my loved one died from mantle cell lymphoma after Roundup exposure?

Yes, immediate family members (typically spouses, children, or parents) can often file wrongful death lawsuits on behalf of deceased loved ones. These cases typically need to be filed within 1-3 years of the date of death, though this varies by state. These claims may include compensation for medical expenses, funeral costs, lost income, and loss of companionship.

6. Does Roundup still contain glyphosate?

Yes, most Roundup products still contain glyphosate as their active ingredient. While Bayer (which acquired Monsanto) has announced plans to offer some glyphosate-free versions for the U.S. residential market starting in 2023, the vast majority of Roundup products worldwide still contain glyphosate, including all formulations for agricultural use.

7. How long does it take for a Roundup mantle cell lymphoma lawsuit to resolve?

Resolution timeframes vary significantly, from 1-5 years depending on case complexity and whether it settles or goes to trial. Cases with strong evidence of significant Roundup exposure and clear medical documentation may resolve faster. Many cases are now being processed through the established settlement program, potentially expediting resolution.

8. Can I file a claim if I used Roundup for home gardening rather than occupational exposure?

Yes, individuals who used Roundup regularly for home gardening or lawn care can qualify for legal claims. While occupational exposure often involves higher quantities, regular home use over several years has been recognized in successful lawsuits. Documented regular use (through receipts, photographs, or witness statements) strengthens home gardener claims.

9. How is glyphosate thought to cause mantle cell lymphoma?

Research suggests multiple mechanisms: glyphosate may damage DNA in lymphocytes, disrupt normal cell division, cause oxidative stress, interfere with hormone systems, and alter the gut microbiome which affects immune function. These biological processes can lead to the specific genetic mutations associated with mantle cell lymphoma development.

10. Do I need to have used Roundup brand specifically, or do lawsuits cover other glyphosate herbicides?

While most litigation has focused on Roundup, lawsuits may cover other glyphosate-based herbicides as well. The key factors are that the product contained glyphosate and that you were exposed to it before developing cancer. Your attorney can help evaluate claims involving non-Roundup branded glyphosate products.
