Cancer risks of RoundUp
Over 4,000 cancer patients are suing Monsanto in numerous state courts for failure to warn the public about the risk of cancer associated with RoundUp weedkiller. The World Health Organization’s International Agency for Research on Cancer published a report[204] linking glyphosate (the chemical in RoundUp) to cancer for humans. Monsanto denies that Roundup is carcinogenic.[205][206]

On August 10, 2018, a San Francisco jury in a superior court, awarded Dewayne Johnson $289 million dollars in damages for linking his terminal cancer (non-Hodgkin’s lymphoma) to RoundUp weedkiller.[206]
