Abstract:
The serum copper levels were investigated in 125 patients with solid tumors: 34 patients with bronchial cancer, 35 with gastric cancer, 31 with breast cancer and 25 with melanoma. Analysis showed that serum copper was extremely high in 82% of the patients with bronchial carcinoma, while in the other examined groups no significant changes were observed. According to these results, serum copper could be a diagnostic factor in patients with bronchial carcinoma.
