Both Diabetes and breast cancer are common chronic diseases in women. Nearly 16% of breast cancer patients have diabetes.

Aim: This study was aiming to assess the level of CD44 and ILGF 1 in female patients with breast cancer with and without type II diabetes mellitus.

Patients and Methods: 53 Egyptian females with breast cancer had attended Minia Oncology Center. They were classified into 2 groups according to the presence of diabetes. Tissue CD44 and Tissue IGF-1 receptors expression, Estrogen Receptors, Progesterone Receptors expression were all estimated.

Results: Egyptian females with breast cancer and diabetes had significantly higher IGF-1R and higher CD44 Expression and lower ER and PR Expression in malignant.

Conclusion: The presence of diabetes mellitus may be an important contributor to breast cancer risk among Egyptian females. Both IGF-1R and/or CD44 over-expression associated with poor clinicpathological outcomes of breast cancers among diabetic females.
