Is glyphosate a cancer risk? It depends on your gauge.

The International Agency for Research on Cancer started a global debate by rating glyphosate, the most widely used weedkiller in the world, as "probably carcinogenic to humans" while the EPA says its studies indicate it is "not likely to be carcinogenic to humans at doses relevant to human health." Harvest Public Media says the difference in view is partially explained by the way the agencies chose to evaluate the issue.

Good news for coffee drinkers—WHO agency says no conclusive cancer risk

An exhaustive review of research finds no conclusive evidence of a risk of cancer from drinking coffee, said the International Agency for Research on Cancer in its first look at the hot drink since 1991, when it found a weak link to cancer of the bladder. On the five-point scale used by the WHO agency, the only lower rating than "not classifiable" for coffee is "probably not carcinogenic."

WHO agency says 2,4-D weedkiller is “possibly carcinogenic”

The weedkiller 2,4-D is "possibly carcinogenic to humans," says the International Agency for Research of Cancer, the same WHO agency that classified glyphosate, the most widely used weedkiller in the world, as probably carcinogenic.

Green groups ask EPA to re-evaluate weedkiller glyphosate

The EPA should conduct "an urgent re-evaluation" of glyphosate, one of the most widely used pesticides in the world, in response to a determination by a World Health Organization agency that the weedkiller is probably carcinogenic for humans, said eight environmental groups.

Widely used herbicide glyphosate is “probably carcinogenic”

The herbicide glyphosate, widely used in U.S. crop production, especially for genetically engineered corn and soybeans, is "probably carcinogenic to humans," says the specialized cancer agency of the UN World Health Organization. The herbicide is known under the brand name RoundUp in the United States. The International Agency for Research on Cancer reviewed glyphosate and four other organophosates on the recommendation of an advisory committee that dozens of pesticides should be examined because...

WHO advisers analyze weedkiller 2,4-D for cancer risk

A panel of two dozen scientists begins a week-long meeting today in Lyon, France, to "analyze scientific findings regarding links between cancer in humans and the herbicide known as 2,4-D," says Reuters.
