Abstract:
A round lump with a well-defined outline is, in most cases, benign. However, in 10 to 20% of all cases, a round and well-defined lump may correspond to a cancer. Most often, it consists of grade III infiltrating ductal carcinoma (IDC). Other histological sub-types may provide round masses with smooth contours: colloid carcinoma (still called mucinous carcinoma), medullary carcinoma, intramammary metastases, intra-cystic papillary carcinoma, lymphoma and high-grade phyllode tumours.
