Breast Lump

  • BBSG – Brazilian Breast Study Group


A breast lump refers to every tumor present in the mammary gland. It may present cystic or solid content, might be palpable to the clinical examination or not, and is considered one of the most common reasons to access medical aid and may reach 60% of the specialist consultations. Most patients will present benign pathologies (70–75% of diagnoses).

Two studies pointed in favor to the relative risk of breast cancer in fibroadenomas without hyperplasia between 1.48 and 1.7, fibroadenoma with hyperplasia between 3.47 and 3.7 and fibroadenoma with hyperplasia and atypia between 6.9 and 7.29, as the risk remains for more than 20 years after diagnosis. It suggests to improve the concern directed for patients with fibroadenoma associated with hyperplasia, with or without atypia.CrossRefGoogle Scholar

The presence of proliferative lesions in biopsies, patients’ age and family history are determinant factors to evaluate the risk of breast cancer. Apparently, there was no association between the presence of atypia and family history in determining the riskCrossRefGoogle Scholar

The vacuum-assisted puncture for non-palpable nodules has shown to be less specific when compared to percutaneous biopsy. In tangible lesions, the specificity of the vacuum-assisted puncture increases when the triple diagnosis is associated: physical examination, image and cytologyCrossRefGoogle Scholar

Retrospective study with 347 women under the age of 25 who presented nodules with benign characteristics and were still subjected to biopsy by coarse needle. Divergence was present in just one case, in which invasive carcinoma was diagnosed. It concludes that in young women with nodules whose ultrasonographic analysis is benign, do not require histological diagnosis.CrossRefGoogle Scholar
