Ultrasound (US) diagnosis of nonpalpable breast cancer
1Graduate School of Comprehensive Human Sciences, Institute of Clinical Medicine, University of Tsukuba, Tsukuba, Ibaraki, 305-8575, Japan.
Background:
Ultrasound (US) is a standard modality to diagnose breast diseases. To elucidate the usefulness of US in the diagnosis of nonpalpable breast cancers, we reviewed the cases that were treated at our institution.
Methods:
Of the 106 cancers that were operated upon at the Tsukuba University Hospital between February 2004 and March 2005, 12 cancers were nonpalpable. We reviewed their US findings, results of US-guided fine needle aspiration cytology (FNAC), core biopsy results, and histological diagnoses.
Results:
On US, 9 tumors appeared as masses. The US observations were valuable, but a confirmatory diagnosis could not be made. US-guided FNAC was performed in 8 cases; malignancy was suspected in 6 cases. US-guided core biopsy was performed in 9 cases, and it was diagnostic in 7 cases.
Conclusions:
Nonpalpable breast cancers can be effectively detected by US, and the diagnosis can be confirmed by US-guided FNAC or core biopsy.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
