tubular carcinoma

Although tubular carcinoma has been considered a special-type tumor,{{efn|Special-type tumor: such as mucinous and cribriform carcinomas.{{citation |title=Understanding Your Pathology Report: Breast Cancer |date=2022 |website=Cancer.org |publisher=American Cancer Society |url=https://www.cancer.org/treatment/understanding-your-diagnosis/tests/understanding-your-pathology-report/breast-pathology/breast-cancer-pathology.html |access-date=26 February 2022}}}} recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS{{efn|NOS: of type "Not Otherwise Specified".{{cite web |title=Farlex Partner Medical Dictionary |date=2009 |url=https://medical-dictionary.thefreedictionary.com/Not+otherwise+specified |at=not otherwise specified |access-date=26 February 2022}}}} carcinomas with tubular features, depending on the percentage of the lesion that displays tubular features.{{rp|647}}

Tubular carcinomas are generally around 1 cm. or smaller, and are made up of tubules. They are usually low-grade. Elastosis has been noted as common but is not present in all cases.{{cite book |editor-last=Rosen |editor-first=Paul Peter |date=2001 |title=Rosen's Breast Pathology |publisher=Lippincott Williams & Wilkins |pages=373– |isbn=978-0-7817-2379-4 |oclc=1117861419 |url=https://books.google.com/books?id=_DJvdehOkzgC&pg=PA373}}

Prevalence has previously been controversial, with contradictory reports from studies reporting either very low prevalence, or a high prevalence.{{cite book |last=Stavros |first=A.

Tubular carcinoma is one of the histologic types of breast cancer with a more favorable outcome.{{cite web |title=Breast Cancer Treatment (Adult) (PDQ®)–Health Professional Version |date=20 January 2022 |url=https://www.cancer.gov/types/breast/hp/breast-treatment-pdq |publisher=National Cancer Institute |access-date=26 February 2022}}
