[[Mammography]] is the gold standard test for the diagnosis of [[breast lumps]] in women aged >40 years old. [[Ultrasound]] is the gold standard test for the diagnosis of [[breast lumps]] in women aged <40 years old. Management and medical therapy of [[breast lumps]] depends on women's age (age> 40 or age <40) and [[mammography]] results in women aged > 40 years. In women aged > 40 years; no further evaluation is needed in case of clearly [[benign]] mass in [[mammography]]; however, [[ultrasound]] imaging is required for the rest of the findings [[mammography]]. Approach to breast lumps in women >40 years is depended on breast imaging reporting and data systems (BI-RADS) stages. Medical therapy of breast lumps in women< 40 years is depended on [[ultrasound]] results and BI-RADS categories.

Overview

Mammography is the gold standard test for the diagnosis of breast lumps in women aged >40 years old. Ultrasound is the gold standard test for the diagnosis of breast lumps in women aged <40 years old. Management and medical therapy of breast lumps depends on women's age (age> 40 or age <40) and mammography results in women aged > 40 years. In women aged > 40 years; no further evaluation is needed in case of clearly benign mass in mammography; however, ultrasound imaging is required for the rest of the findings mammography. Approach to breast lumps in women >40 years is depended on breast imaging reporting and data systems (BI-RADS) stages. Medical therapy of breast lumps in women< 40 years is depended on ultrasound results and BI-RADS categories.

Diagnostic Study of Choice

Gold Standard

Mammography

Mammography is the gold standard test for the diagnosis of breast lumps in women aged >40 years old.[1]

Ultrasound

Ultrasound is the gold standard test for the diagnosis of breast lumps in women aged <40 years old.[1]

The comparison of various diagnostic studies for breast lumps:[2]

Sensitivity Specificity
Ultrasound 82% 84%
Mammography 49% 89%

Breast ultrasound has higher sensitivity and mammography has higher specificity. The accuracy of ultrasound reported as 84% and accuracy of mammography reported as 81% .[2]

Diagnostic Approach to Breast Lump

Diagnostic approach for breast lump:

Approach to breast lumps in women aged > 40 years based on mammographic results:[3]

  • If mammographic results become negative, the next step is targeted ultrasound.
    • Negative ultrasound results considered as breast imaging reporting and data system (BI-RADS) 1, then clinical follow-up is needed.
    • Benign ultrasound results considered as BI-RADS 2, then clinical follow-up is needed.
    • Probably benign results considered as BI-RADS 3, then ultrasound short interval follow-up is needed.
    • Suspicious ultrasound results considered as BI-RADS 4 or 5, then core-needle biopsy is needed.
  • If mammographic results show only fatty tissue:
    • Considered as BI-RADS 1, then clinical follow-up is needed.
  • If mammographic results show benign mass:
    • Considered as BI-RADS 2, then clinical follow-up
  • If mammographic results are in favor of probably benign lumps, the next step is targeted ultrasound.
    • Negative ultrasound results considered as BI-RADS 3, then mammographic short interval follow-up is required.
    • Benign ultrasound results considered as BI-RADS 2, then clinical follow-up is required.
    • Probably benign ultrasound results considered as BI-RADS 3, then ultrasound short interval follow-up.
    • Suspicious ultrasound results is considered as BI-RADS 4 or 5, then core needle biopsy is required.
  • If mammographic result is in favor of suspicious lesion, the next step is ultrasound to determine biopsy plan.
    • Considered as BI-RADS 4 or 5, then core needle biopsy is required.

Approach to breast lumps in women aged <40 years based on targeted ultrasound findings:[3]

  • If ultrasound results become negative, there are two approaches:
    • Considered as BI-RADS 1, then clinical follow-up is required ( if no palpable dominant suspicious mass found at clinical examination)
    • Perform diagnostic mammography:
      • Negative results are in favor of BI-RADS 1, then clinical follow-up is required.
      • Benign results are considered as BI-RADS 2, then clinical follow-up is required.
      • Probably benign results considered as BI-RADS 3, Mammographic short interval follow-up is required.
      • Suspicious results considered as BI-RADS 4 or 5, then core needle biopsy is required.
  • If ultrasound results show benign findings:
    • Considered as BI-RADS 2, then clinical follow-up is required.
  • If ultrasound results show probably benign findings:
    • Considered as BI-RADS 3, then short interval follow-up is required.
  • If ultrasound results become suspicious:
    • Considered as BI-RADS 4 or 5, then core needle biopsy is required.
