Roundup is the most widely used herbicide in the world, with glyphosate as its active ingredient. The International Agency for Research on Cancer classified glyphosate as probably carcinogenic to humans in 2015.

Thousands of plaintiffs have sued Monsanto (acquired by Bayer) alleging that occupational or residential exposure to Roundup caused non-Hodgkin lymphoma, including B-cell lymphoma and diffuse large B-cell lymphoma.

Bayer has reached multi-billion-dollar settlement agreements, though new cases continue to be filed. If you used Roundup regularly and were diagnosed with NHL, consult an attorney promptly due to varying statute of limitations.
