Ross Feller Casey, among the nation’s leading catastrophic injury law firms, is actively investigating lawsuits against agricultural giant Monsanto on the basis that its herbicide, Roundup®, causes various types of cancer.

Roundup’s Main Ingredient: A Known Carcinogen

Monsanto’s Roundup is the most widely used herbicide in the world.

In July 2017, California took the bold step of placing the active ingredient in Roundup – glyphosate – on its list of known carcinogens and is requiring warning labels on Roundup products containing the toxin.

That came two years after the World Health Organization, WHO, classified glyphosate as “probably carcinogenic to humans.” The WHO concluded that “there is sufficient evidence of carcinogenicity” in experimental animals and humans in an agricultural setting. It found that glyphosate caused DNA and chromosomal damage in human cells and identified a link between glyphosate and cancer — particularly non-Hodgkin’s lymphoma and other hematopoietic cancers, including hairy cell leukemia, lymphocytic lymphoma/chronic lymphocytic leukemia, and B-cell lymphoma.

Who is at Risk?

People most at risk of developing cancer as a result of Roundup exposure are those who use it regularly, such as landscapers, nursery workers and farmers. But those who use the product often on their own lawns and gardens are also at risk. 

How was I Exposed?

There are various methods of exposure to glyphosate:

  • Air - inhalation, especially during spraying
  • Water - surface and groundwater used for drinking and cooking
  • Food - glyphosate found in soil/food


For decades, Monsanto has known that Roundup was carcinogenic, yet falsely and aggressively advertised it as safe. In fact, the laboratories hired by Monsanto to test the toxicity of Roundup were twice found to have committed fraud by submitting false data and using fraudulent laboratory practices.

Despite the scientific evidence, Monsanto continued to aggressively tout Roundup as safe. Lawsuits against Monsanto are mounting as more and more people become aware of the connection between Roundup and cancer and various birth defects.

Litigation So Far

In August 2018, a federal jury in San Francisco smacked Monsanto with $289 million in damages – including $250 million in punitive damages – in a case involving school groundskeeper Dewayne Johnson, 46, who developed cancer after frequently using Roundup for years. The landmark verdict was the first of hundreds of other cases awaiting trial in courts across the nation alleging Roundup caused several types of cancers and that Monsanto covered up the risks of its product.

Several studies have linked glyphosate, Roundup’s main ingredient, to serious, potentially deadly, side effects, including fetal death, and:

  • Non-Hodgkin Lymphoma, including
    • Large Cell B Lymphoma
    • Anaplastic Large Cell Lymphoma
    • Chronic Lymphocytic Leukemia
    • Hairy Cell Leukemia
  • Lymphoma
  • Leukemia
  • Other cancers
