[Present-day diagnostic techniques in breast nodes]

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Accurate preoperative diagnosis of breast lesions is crucial for effective treatment planning.
• Conventional imaging techniques like mammography, ultrasound, and aspiration biopsy have varying diagnostic capabilities.

Purpose of the Study:

• To compare the effectiveness of preoperative diagnostic techniques for breast nodes.
• To evaluate a novel ultrasound histography technique for enhancing diagnostic specificity.

Main Methods:

• A comparative analysis involving 110 females with breast cancer and 306 with benign breast tumors.
• Assessment of mammography, ultrasound, and aspiration biopsy.
• Introduction of ultrasound histography for improved echography specificity.

Main Results:

• Diagnostic sensitivity: mammography (82.8%), ultrasound (88.3%), aspiration biopsy (69.3%).
• Reduced informative value of mammography and aspiration biopsy in reproductive-aged females, particularly with hyperplastic processes.
• Ultrasound sensitivity increases with tumor size, but specificity decreases.

Conclusions:

• Ultrasound is a sensitive tool for breast tumor diagnosis, with sensitivity increasing for larger tumors.
• Ultrasound histography is beneficial for improving diagnostic specificity in cases of larger breast tumors.
