CANCER Diagnostic Examinations
Diagnostic Examinations are done to: ﭻ1. Determine the presence of tumor and
its extent. ﭻ2. Identify possible spread (metastasis) of disease or invasion of other body tissues. ﭻ3. Evaluate the function of involved and uninvolved body systems and organs. ﭻ4. Obtain tissue and cells for analysis, including evaluation of tumor stage and grade.
Tumor Marker Identification ﭺDescription: Analysis of substances found in blood or other body fluids that are made by the tumor or by in response to tumor
ﭺDiagnostic Uses: ﭺBreast ﭺColon ﭺLung ﭺOvarian ﭺTesticular ﭺProstate Cancer
Magnetic Resonance Imaging (MRI) ﭽDescription: Use of magnetic fields and radiofrequency signals to create sectioned images of various body structures.
ﭽDiagnostic Uses: ﭽNeurologic ﭽPelvic ﭽAbdominal ﭽThoracic Cancers
Computed Tomography (CT) Description: Use of narrowbeam x-ray to scan successive layers of tissue for crosssectional view.
Diagnostic Uses: Neurologic Pelvic Skeletal Abdominal Thoracic Cancers
Fluroscopy Description: Uses of X-ray that identify contrast in body tissue densities; may involve the use of contrast agents.
Diagnostic Uses: Skeletal Lung Gastrointestinal Cancers
Ultrasonography (Ultrasound) ﭼDescription: High-frequency sound waves echoing off body tissues are converted electronically into images; used to asses tissue deep within the body.
ﭼDiagnostic Uses: ﭼAbdominal ﭼPelvic Cancers
Endoscopy ﺕDescription: Direct visualization of body cavity or passageway by insertion of an endoscope into the body cavity or opening; allows tissue biopsy, fluid aspiration, and excision of small tumors; both diagnostic and
ﺕDiagnostic Uses: ﺕBronchial ﺕGastrointestinal Cancers
Nuclear Medicine Imaging ۞ Description: Uses intravenous injection or ingestion of radioisotope substances followed by imaging of tissues that have concentrated the radioisotopes.

Bone Liver Kidney Spleen Brain Thyroid Cancers
Positron Emission Tomography ( PET) ۩Description:
Through the use of a tracer; provides black and white or color-coded images of the biologic activity of a particular area, rather than it’s structure; used in detection of cancer or it’s response to treatment.
۩Diagnostic Uses: ۩ Lung ۩ Colon ۩ Liver ۩ Pancreatic ۩ Head and Neck ۩ Hodgkin and Non-
Hodgkin ۩ Lymphoma and Melanoma Cancers
PET Fusion Description: Use of a PET scanner and a CT scanner in one machine to provide an image combining anatomic detail, spatial resolution, and functional metabolic abnormalities.
Diagnostic Uses:
The same as PET.
Radioimmunoconjugates ﭹDescription: Monoclonal antibodies are labeled with a radioisotope and injected intravenously into the patient; the antibodies that aggregate at the tumor site are visualized with scanner.
ﭹDiagnostic Uses: ﭹColorectal ﭹBreast ﭹOvarian ﭹHead and Neck ﭹLymphoma and
Melanoma Cancers
Nursing Responsibilities: ﺖHave a complete history and
physical examination. ﺖRelieve patients anxiety through: *Explaining the test to be performed. *The sensations likely to be experienced. *Patients role in the test procedure.
Nursing Responsibilities: ﺖEncourage the patient and family to voice their fears about test results. ﺖSupport the family throughout the test period. ﺖReinforce and clarify information conveyed by the physician. ﺖEncourage patient and family to communicate and share concerns and to discuss their questions and concerns with each other.
