Dihydrogen Monoxide and Cancer

A review of observed associations between Dihydrogen Monoxide (DHMO) exposure and cancerous conditions.

Publication Date: June 2026
Classification: Public Release
Office: Cancer Research Unit
Research Advisory

Current evidence neither confirms nor excludes a causal relationship between DHMO exposure and cancer formation. Ongoing monitoring efforts continue.

Abstract

The causative link between Dihydrogen Monoxide (DHMO) and cancer has not been established. However, significant evidence suggests that DHMO may play a role in the development, progression, or persistence of a wide variety of cancerous conditions. Additional research is warranted.

Background

The causative link between Dihydrogen Monoxide and cancer is currently not established, although a significant amount of evidence suggests that DHMO may play a role in the formation or progression of various cancers.

Researchers continue to investigate the prevalence of DHMO in cancerous and pre-cancerous tissues and the possible mechanisms through which it may contribute to disease processes.

Observed Cancer Associations

DHMO has been identified in biologically significant quantities in numerous cancerous and pre-cancerous conditions including:

  • Hodgkin's lymphoma
  • Ewing's tumor
  • Chondrosarcoma
  • Fibrosarcoma
  • Multiple myeloma
  • Colorectal cancer
  • Leukemia
  • Basal cell carcinoma
  • Squamous cell carcinoma
  • Malignant melanoma

Detection and Treatment

Dihydrogen Monoxide is found in detectable and biologically significant levels in virtually all tumors and other cancerous and pre-cancerous growths.

Cancer research has made significant advances in the detection and treatment of many forms of cancer. With each advancement, the role DHMO may play in cancer development is likely to become better understood.

Carcinogenicity Assessment

DHMO is not presently believed to be carcinogenic. However, it is known to be a component of a number of cancer-causing agents.

Approximately twenty percent of all cancers remain of unknown origin. Researchers continue to investigate whether DHMO may contribute to some of these cases.

Additional investigation is necessary before DHMO's role can be fully characterized.

Supporting Researchers

Medical imaging and hospital information systems play an important role in diagnosing, tracking, and studying cancer patterns within the population.

DHMO.org supports efforts to develop technologies that improve interoperability among DICOM medical imaging software systems, radiology reading and dignostic systmes, and healthcare information networks.

Free DHMO testing remains available to software professionals working to advance cancer research through DICOM development.
