According to experts, a weedkiller that is used in many gardens across the world, has been identified as a potential cancer risk. A group of 17 international scientists have been asked by the World Health Organization's cancer agency to make a decision whether glyphosate posed a risk to humans.

According to the International Agency for Research on Cancer (IARC), it has been declared that the chemical, which is the world's most commonly used weedkiller is a 'probable human carcinogen'.

According to the experts, Glyphosate is most normally used in the popular weedkiller Roundup and it is prepared by the American agro-chemical giant Monsanto. The company sells the herbicide to farmers in the United States. In the United States, crops can be genetically modified to provide them immunity to glyphosate.

In the past decade, use of the chemical has increased and it's found in water and food on the shelves in the UK, involving bread and cereal bars. According to the IARC report, 750 products have glyphosate and use of it has mounted with the development of GM glyphosate-resistant crop varieties.

Researchers studied evidence from studies that published in the United States, Canada, and Sweden since 2001. The researchers reached to the conclusion that there was proof that glyphosate can cause tumours in mice and rats in laboratory experiments. There is also a possibility that glyphosate can cause DNA damage to human cells.
