Other diagnostic studies for<unk>  cancer include Fluoro-D-glucose positron emission tomography (PET)-CT which shows increased uptake of tumor  metabolic cells. Fluoro-D-glucose positron emission tomography (PET)-CT may be performed to detect late stages of<unk>  cancer and inaccessible regions by endoscopy. Endoscopy can be useful in detecting primary tumor invasion and biopsy.
