Introduction to Breast Diagnostic Algorithm 9 Back a Page Introduction to Algorithm 9 Management of Tissue Biopsy Results from Breast Lesions Definitive diagnosis of a breast mass can only be established through FNAB, core needle, or excisional biopsy.
Experts agree that if a mass persists for three months, a sampling of the lesion is warranted.
Further delay in work-up is not prudent. Breast biopsy techniques are grouped into two categories according to whether the mass is palpable or non-palpable. Palpable masses Biopsy options for palpable masses include FNAB, large gauge needle core biopsy and excisional biopsy. FNAB extracts cells rather than tissue and has been described in the text for Algorithm 8. This technique is relatively simple, minimally invasive, and can be performed in a variety of outpatient settings.
