Chemicals like glyphosate are one of the most frequently used pesticides on the market.

They are also used in many of the agricultural products that are often marketed as organic.

But studies have shown that these chemicals can have adverse effects on humans, including cancer.

The most recent research, which was published in the Journal of the American Medical Association, concluded that glyphosate, a widely used herbicide in Europe, has been linked to cancer.

“Our research indicates that exposure to glyphosate-based herbicides can lead to increased risk of cancer in humans,” said lead author, Dr. Yuliya S. Shikhala, from the University of Pennsylvania.

The findings could help determine if glyphosate is the culprit behind the recent increase in cases of cancer reported in the US.

Shimon Seidler, an associate professor of epidemiology at the University at Albany, and colleagues looked at data from more than 4,000 cancer cases in the United States.

“The data is quite clear,” he said.

“We found a strong association between glyphosate exposure and an increased risk for cancer.

So that’s what we were looking at.”

Shikhalas team analyzed data from the US, France, Italy, Canada, and Japan.

They also looked at cases of prostate cancer and pancreatic cancer.

Their research found that exposure in these countries to glyphosate, as well as other herbicides, was associated with an increased chance of developing cancer.

In the US and Europe, there were 4.7 and 6.2 cases of colorectal cancer and 3.6 and 3 cases of non-Hodgkin’s lymphoma, respectively, for each 1,000 person-years of exposure to the chemicals.

“It’s a pretty big jump,” said Shikalas.

“But in general, we saw a clear increase in cancers.”

Shihla said that the study also shows that exposure can be linked to other diseases, like other cancers in people who have other genetic diseases.

He also noted that this study does not prove that glyphosate causes cancer.

But he said that if people are exposed to other chemicals, they can become more susceptible to developing cancer, which could have an effect on the overall population.

“If the cancer is not diagnosed early, then it can be more difficult to stop it,” said Seidlers co-author, Dr Maria V. Gavrozny, from Harvard Medical School.

The study was funded by the National Institutes of Health (NIH) Office of Biological Sciences, the US Department of Agriculture, the United Nations Environment Programme (UNEP), the United Kingdom Department of Health and Human Services, and the European Commission.

The research was published online on December 21, 2016 in JAMA.
