Features of Structure of External Layer of Murine Hair at Different Stages of Malignant Tumor Development

The study investigated the structural differences in the hair of healthy mice compared to those with malignant tumors. It was found that as the tumor developed, the structure of the hair deteriorated, with a decrease in the number and thickness of cells in the external hair layer. These changes were observable even when the tumor was small. The findings suggested potential improvements in optical techniques for biomedical cancer diagnostics.
