The neoplasmic process causes the disturbance of magnesium metabolism in the organism. The studies were conducted in order to determine magnesium concentration in the tissues and serum of dogs with malignant and non‐malignant mammary tumours in comparison to its concentration in the tissue and serum of healthy dogs. From the studies presented in the paper it turns out that magnesium concentration in the mammary neoplasmic tissue increases with the increase of tumour malignancy and in comparison to its concentration in the control tissue. Magnesium concentration in the blood serum decreases with the increase of tumour malignancy and in comparison to the control tissue. Therefore it was shown that there is a connection between the degree of tumour malignancy and magnesium concentration in the tissue and serum.
