Summary
This review examines trace elements like fluorine and zinc, exploring their dual role in cancer causation or inhibition. Assays for these elements in biological fluids may aid cancer diagnosis and prognosis.
Area of Science:
- Environmental Science
- Biochemistry
- Oncology
Background:
- Trace elements are essential micronutrients with diverse biological functions.
- Aberrant levels of certain trace elements have been implicated in various pathologies, including cancer.
- Understanding the complex interplay between trace elements and cancer is crucial for developing novel therapeutic and diagnostic strategies.
Purpose of the Study:
- To review the role of specific trace elements (fluorine, copper, manganese, zinc, cobalt, chromium, selenium, molybdenum, tin, vanadium, silicon, and nickel) in cancer.
- To evaluate their potential as causative or inhibitory agents in cancer development.
- To explore the utility of biological fluid assays for trace elements as diagnostic or prognostic biomarkers in cancer patients.
Main Methods:
- Comprehensive literature review of studies investigating trace elements and cancer.
- Analysis of data on the association between trace element levels and cancer incidence/progression.
- Evaluation of research on the diagnostic and prognostic value of trace element assays.
Main Results:
- Evidence suggests that certain trace elements can act as either carcinogens or anti-cancer agents.
- Variations in trace element concentrations in biological fluids correlate with cancer status.
- The potential for using trace element analysis as a non-invasive diagnostic/prognostic tool is under investigation.
Conclusions:
- Trace elements play a significant, albeit complex, role in cancer etiology.
- Further research is warranted to elucidate the precise mechanisms of trace element action in cancer.
- Trace element profiling in biological fluids holds promise for cancer diagnostics and prognostics.
