Keratin 17 Oncoprotein Potential Cervical Cancer Biomarker

The keratin protein K17, which was thought to play a purely passive mechanical support role for tumors, has been shown to act as a cancer-promoting oncoprotein whose expression by cervical cancer cells is linked to decreased likelihood of survival.   More...

Testicular Cancer Risk Comes from Inherited Genetic Faults

Testing for a range of genetic variants linked to testicular cancer could be effective in picking out patients who are at substantially increased risk, and therefore, potentially opening up ways of preventing the disease.  More...

Independent Prognostic Biomarker Found for Klatskin Tumor Patients

Curative treatment of intrahepatic cholangiocarcinoma and hilar cholangiocarcinoma is limited to surgical resection or orthotopic liver transplantation, however, not all patients benefit from a surgical approach and suffer from early tumor recurrence.  More...

Breast Cancer Diagnosis Uses Spatial Light Interference Microscopy

The standard practice in histopathology of breast cancers is to examine a hematoxylin and eosin stained tissue biopsy under a microscope to diagnose whether a lesion is benign or malignant.  More...
