Aim of Study: Breast cancer invasion and metastasis is the main reason for the failure, and laminin is involved in it. This study intends to explore the expression of laminin in breast cancer and normal breast tissue and its clinical significance. Materials and Methods: We use immunohistochemical assay for the detection of breast infiltrating ductal cancer tissues and normal breast tissues of laminin expression and discuss their role in breast cancer invasion and metastasis. Results: Our results showed that laminin was positive expressed in normal breast tissue, and strongly positive expressed but lost its' continuity in the breast cancer tissue. Conclusion: This results revealed laminin is involved in breast cancer invasion and metastasis, and we can use this to determine whether the integrity of a basement membrane for differential diagnosis of benign and malignant breast tumors.
