Thyroid papillary cancers: microcarcinoma and carcinoma, incidental cancers and non‐incidental cancers – are they different diseases?

Abstract

Non-incidental cancer, apart from multifocality, showed a classical progression for all prognostic factors from microcarcinoma to larger cancers. However, real incidental PC seemed to be different from non-incidental PC microcarcinoma regarding the main prognostic features. We conclude that ultrasonography is useful not only in terms of revealing the presence of cancer but also in identifying the most aggressive cancers.
