Why this record matters
The phrase “benign, borderline, or malignant neoplasm involving the ovary” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Aug 27, 2026. The linked authority identifier is Q11793790. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020 and 1882.
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.
