Abstract

Introduction

Breast cancer develops in breast tissues, in ducts and lobules. It affects both genders, though it is uncommon in men. Hematological variations are important considerations and deficiencies in metals can negatively impact human health. Cadmium is highly toxic and plays role in breast cancer progression. This study was designed for hematological variations and cadmium induced toxicity in mice and humans causing breast cancer.

Methods

Mice, obtained from local supplier, housed at university laboratory for 11 weeks, exposed to cadmium. Following dissection, blood and organs were harvested for examination. Histological analysis of liver and mammary gland tissues was conducted.

Results

Affected mice had higher Hb, RBC, HCT, MCV, and MCH, while humans showed lower Hb, HCT, and MCV but similar RBC and MCH. Other blood values also show changes. Histopathology revealed changes in mammary glands (higher cadmium led to increased fat deposition, degeneration of alveolar epithelial cells, and a reduction in alveolar milk lumen size, indicating compromised glandular function) and Liver damage (vacuolation, lipid accumulation, fibrosis, and collagen deposition, was noticeable with prolonged cadmium). These changes causes liver fibrosis and impaired mammary gland function.

Discussion

The cadmium exposure induces distinct hematological alterations and severe tissues damage, reflecting species-specific responses. The observed liver fibrosis and mammary gland dysfunction emphasize cadmium’s potential to compromise critical organ functions over time.

Conclusion

Significant effects of cadmium exposure in mice were observed. Histological damage was seen in mammary glands and liver. Further research on protective measures and dose-response relationships for cadmium exposure is needed.
