Cancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic disease and one or more biopsy results inconsistent with a tumor cancer.
Despite the generic-sounding name, "CUP" is a specific cancer diagnosis that requires extensive testing. Individuals should only be placed in this category if a reliable source reports that they died from a cancer in which doctors attempted to but could not identify a primary tumor, and not for people whose cancer type is unknown.
Most cancers continue to be called after their primary site, as in breast cancer or lung cancer for example, even after they have spread to other parts of the body. Cancer of unknown primary origin is cancer that is determined to be at the metastatic stage, but a primary tumor cannot be identified.
It is estimated that 3% of all cancers are of unknown primary origin. [33] Studies have shown that, if simple questioning does not reveal the cancer's source (coughing up blood—"probably lung", urinating blood—"probably bladder"), complex imaging will not either. [33] In some of these cases a primary tumor may appear later. [citation needed]
Primary peritoneal cancer or carcinoma is also known as serous surface papillary carcinoma, primary peritoneal carcinoma, extra-ovarian serous carcinoma, primary serous papillary carcinoma, and psammomacarcinoma. It was historically classified under "carcinoma of unknown primary" (CUP).
Gynecological cancers account for about 1 in 4 cases (primarily ovarian cancer and also uterine cancer). Nodules will also, rarely, originate from appendix cancer spillage and pseudomyxoma peritonei. Unknown primary tumors and rarely, urinary or respiratory tract malignancies can cause umbilical metastases. [4]
