Breast disease
thoracic disease that is located in the breast
Breast diseases make up a number of conditions. The most common symptoms are a breast mass, breast pain, and nipple discharge.
A majority of breast diseases are noncancerous.
Although breast disease may be benign, or non-life threatening there remains an associated risk with potentially a higher risk of developing breast cancer later on.
Tumor
A breast tumor is an abnormal mass of tissue in the breast as a result of neoplasia. A breast neoplasm may be benign, as in fibroadenoma, or it may be malignant, in which case it is termed breast cancer. Either case commonly presents as a breast lump. Approximately 7% of breast lumps are fibroadenomas and 10% are breast cancer, the rest being other benign conditions or no disease.
Phyllodes tumor is a fibroepithelial tumor which can be benign, borderline or malignant.
Breast cancer
Breast cancer is cancer of the breast tissues, most commonly arising from the milk ducts.
“Breast disease” enters the record as thoracic disease that is located in the breast. Crown Archives preserves that source wording while asking what Breast, disease and thoracic can confirm, complicate or overturn.
Why this record matters
“Breast disease” is worth following because a concise public description often conceals a longer documentary argument. Here, Breast, disease and thoracic provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 17, 2025. The linked authority identifier is Q4959796.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
