Background and Objective: Breast cancer is the commonest cancer of Indian women. Estrogen and Progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. Although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...

Background: Prostate cancer is currently the third malignant disease in Iran and fifth common cancer worldwide. The aim of this study was to determine the expression of GPRC6A, E.cadherin, and ZEB1 genes in prostate cancer in comparison with benign tumor. Since early detection of cancer plays an important role in treatment, this study aims to identify the role of GPRC6A, E.cadherin and ZEB1 gen...

Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas. However, whether orosomuc...

metallothionein (mt) manifests varying expression levels in carcinomas, and they may be considered as valuable cell cancerization biomarkers for diagnosis of patients with cancers. a meta-analysis was conducted to evaluate comprehensively the mt expression difference in various benign tumors and malignant tumors, which compared the high with low mt expression levels in patients of the available...

background : meningiomas are common benign tumors of the central nervous system. patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. this study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. materials and met...

conclusions: despite its known shortcomings, like every other diagnostic tool, panoramic radiography can contribute to the early detection of maxillary/mandibular lesions that in turn enable the dentist to devise an appropriate treatment plan. results: cysts were mostly more common in men despite the equal propensity of both genders to benign tumors. in contrast, women showed a higher frequency...

discussion benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. it remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy. ...
