Medicines that kill cancer cells can affect normal cells, too. Some of the side effects from workplace exposure may include skin rash, hair loss, nausea, hearing loss, damage to the liver, heart, or kidneys, infertility, birth defects, and cancer.
The National Institute of Occupational Safety and Health (NIOSH) publishes a list of hazardous medicines that is updated every two years. It can be found at https://www.cdc.gov/niosh/docs/2016-161/default.html.
