Overview

Diagnostic Study of Choice

Study of choice

Biopsy is the gold standard test for the diagnosis of breast cancer. Either fine needle aspiration (FNA), core needle aspiration, or surgical biopsy (excisional biopsy) might be the first step or confirmatory test in selected patients. Meanwhile, the diagnostic study of choice for breast cancer screening is mammography. Magnetic resonance imaging (MRI) is also recommended in selected patients. Compared to the Mammography, MRI has higher sensitivity and lower specificity. For more information please refer to breast cancer screening.

Investigations:

  • Among the patients who present with clinical signs of breast cancer, the Mammography is the most specific test for the diagnosis.
  • Estimates of mammography sensitivity range between 75% and 90% with specificity between 90% and 95%. The PPV ranges from 20% in women under age 50 to 60% to 80% in women age 50-69. Although there are reports of the sensitivity (67.8%) and specificity (75%), particularly in older studies.
  • Among the patients who present with clinical signs of breast cancer, the MRI is the most sensitive test for diagnosis.

The comparison of various diagnostic studies for breast cancer

Test Sensitivity Specificity
Mammography 75-90% 90-95%
Breast MRI 37-97% 99%

[Name of test with higher sensitivity and specificity] is the preferred investigation based on the sensitivity and specificity

Diagnostic results

The following finding(s) on performing [investigation name] is(are) confirmatory for breast cancer:

  • [Finding 1]
  • [Finding 2]
Sequence of Diagnostic Studies

The [name of investigation] must be performed when:

  • The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
  • A positive [test] is detected in the patient, to confirm the diagnosis.

OR

The various investigations must be performed in the following order:

  • [Initial investigation]
  • [2nd investigation]
