Millions of Americans take Zantac or generic versions of the drug ranitidine for treatment of heartburn and acid reflux. While drug makers marketed it as safe and effective, recent evidence suggests that the drug contains unsafe levels of N-Nitrosodimethylamine (NDMA), a substance classified as a probable human carcinogen by the Environmental Protection Agency, the World Health Organization, and the Occupational Safety and Health Administration.

Cancers that may be associated with taking Zantac/ranitidine include:

  • Bladder cancer
  • Colon cancer
  • Esophageal cancer
  • Kidney cancer
  • Liver cancer
  • Pancreatic cancer
  • Small intestine cancer
  • Stomach cancer
  • Testicular cancer
  • Uterine cancer
