CONCENTRATIONS OF SOME MAJOR AND MINOR ELEMENTS IN LARYNX TISSUES WITH AND WITHOUT CANCER

In this study, concentrations of some major and minor elements were de termined in the larynx tissues with and without cancer, and results ob tained were statistically compared. No meaningful differences were fou nd between sodium, potassium, calcium and copper concentrations in can cer tissues, corresponding cancer-free adjacent tissues and in control larynx tissues. Phosphate concentrations of the cancer tissues were h igher compared with cancer-free adjacent tissues and control tissues. Iron, zinc and magnesium concentrations were found increased in both c ancer and corresponding cancer-free adjacent tissues relative to contr ol values. Intra- and inter-element correlations established within an d between groups indicated that relations between elements were also d isordered in the cancer tissues. We suggest that the changed element s tatus of cancerous larynx tissues may arise from increased requirement s of cancer tissues for some elements such as iron, zinc, magnesium an d phosphate.
