To file a Roundup cancer claim, you generally must show diagnosed non-Hodgkin lymphoma or a related subtype after Roundup/glyphosate exposure. That means medical proof of the subtype, evidence of regular Roundup use, and facts linking use to illness. Roundup is a glyphosate-based weedkiller. If you used it and later developed lymphoma, lawyers screen your diagnosis, records, work history, and filing deadline before accepting the case.

Which diagnosis qualifies?
Claimants generally must show non-Hodgkin lymphoma or a related subtype after exposure, Motley Rice states in its settlement eligibility guide. Covered subtypes include diffuse large B-cell lymphoma, follicular lymphoma, CLL/SLL, mantle-cell lymphoma, and hairy-cell leukemia.
Other cancers do not meet the main screening rule. A pathology report must name the exact subtype, not only swollen glands or a general cancer finding.
What medical records prove your case?
Medical proof requires a pathology report confirming the NHL subtype plus oncologist notes, lab and imaging results, and treatment history, according to ConsumerShield in its 2026 proof requirements update. Those records tie the diagnosis date to the exposure period.
Ask the hospital for the full file early. Collect these items first: Treatment history also helps set damages. Keep bills, pharmacy lists, and time missed from work with the medical file.
- pathology and biopsy report with NHL subtype
- oncology notes, blood labs, and scans
- surgery, chemo, radiation, and drug records
How do you prove Roundup exposure?
Exposure proof can include receipts, used containers, photos of use, job or landscaping records, coworker statements, or a sworn affidavit if paperwork is missing. Screening often looks for more than one year of use, with occupational guidance citing 80-plus hours and diagnosis at least two years after first exposure. Farm, industrial, turf, and ornamental workers have the clearest paper trail.
Pay stubs, spray logs, task sheets, and employer purchase records can show repeated use. Home users need a different mix. Old receipts, store loyalty history, garden photos, empty jugs, and a neighbor witness can fill gaps when invoices are gone.
How do you connect exposure to illness?
You must connect exposure to illness through expert testimony and show proper product use plus quantifiable damages such as medical bills, lost wages, and pain and suffering. Follow-the-label use matters, so off-label mixing or ignoring safety steps can hurt a claim. Science alone does not decide an individual case.
In March 2015, WHO's IARC classified glyphosate as Group 2A "probably carcinogenic to humans," based on limited human NHL evidence and other data, as described in the IARC announcement. EPA still registers glyphosate for labeled uses while it redoes its human-health review, expected in late 2026. A 2022 federal-court order vacated EPA's 2020 "not likely carcinogenic" finding, so lawyers use experts to bridge general studies to your history.
What limits and deadlines apply?
Monsanto/Bayer proposed a $7.25 billion nationwide class settlement on Feb. 17, 2026, preliminarily approved in St. Louis on March 4, 2026, without admission of liability, Chemical & Engineering News reported.
It covers current and future NHL claims, but class terms can change and do not replace legal advice. Filing deadlines vary by state, typically one to six years from diagnosis or discovery of the Roundup link, Schmidt & Clark notes in its current Roundup filing guide. Late filing can bar recovery even with strong medical and exposure proof. Request pathology files, treatment records, and use evidence now, then get a state-specific deadline check.
