ABSTRACT
Strontium hydroxide Sr(OH)2 has been identified in tumor tissues of patients with melanoma of the vascular coat of the eye and in metastatic tumors to the vascular coat of the eye by x-ray structural analysis. Normal vascular coat of the eye is represented by a mineral natrolite, an adsorbent belonging to zeolites. Presumably, during an oncological process strontium modifies natrolite by changing its adsorption and adhesive properties.

Calcium phosphate, fluoroapatine mineral, Ca5(PO4)3F, characterized by a strong reflex in interplanar distance d = 2.789 A, were identified in the tissue of retinoblastoma by x-ray destructive analysis. The strong reflex intensity and the respective fluoroapatite level in the tumor are the higher, the more malignant the tumor is. The malignancy degree is determined by histologic analysis of the tumor cellular composition after enucleation.
