Popular weedkiller Roundup on trial again as cancer victims demand justice

A long list of upcoming trials complicating Bayer's efforts to escape the costly, ongoing litigation over the health effects of Roundup

Cancer has taken an unrelenting toll on 72-year-old Mike Langford. After being diagnosed with non-Hodgkin lymphoma (NHL) in 2007 he suffered through five recurrences despite multiple rounds of chemotherapy and a stem cell transplant. Now he struggles with chemo-related neuropathy in his arms and legs, and new tests show the cancer is back.

Langford blames his cancer on his longtime use of the popular weed-killing product Roundup, which he applied countless times over decades using a backpack sprayer around his five-acre California property and a vacation lake home. He alleges in a lawsuit that Monsanto, the longtime Roundup maker now owned by the German company Bayer AG, should have warned of a cancer risk.
