Pesticides are commonly used in agriculture to protect crops from pests and diseases. However, some pesticide chemicals have been linked to an increased risk of cancer. For instance, the herbicide glyphosate, found in products like Roundup, has been classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC). Long-term exposure to such chemicals can increase the risk of cancers such as non-Hodgkin lymphoma.
