What does carcinomata mean?
Carcinomata is the classical plural of carcinoma, denoting multiple malignant tumours that originate in epithelial tissue — the cells lining the skin, glands, and internal organs such as the lungs, breast, and colon. Because epithelial cancers account for the large majority of human cancers, the singular term appears constantly in medicine, while the plural carcinomata tends to surface in formal pathology reports and academic literature describing patients with several such tumours or comparing cases across organs. It belongs to a register that favours Greek-derived plurals (alongside terms like stigmata and schemata), though the anglicized plural carcinomas is now at least as common. The word derives from the Greek karkinoma, built on karkinos, meaning crab — a name ancient physicians gave to cancers whose spreading shape reminded them of a crab's limbs.
nounThe plural of carcinoma, referring to multiple malignant tumours that arise from epithelial tissue, such as the skin or the lining of internal organs.
- Plural form of carcinoma: malignant tumours arising from epithelial cells, the most common category of cancer.
"The biopsy revealed carcinomata in both lobes of the liver."
"Pathologists identified several distinct carcinomata during the autopsy."
"The study compared treatment outcomes for patients with advanced carcinomata of the colon and breast."
Both plurals are accepted; "carcinomata" preserves the Greek origin and suits formal medical writing, while "carcinomas" is standard in everyday English.
"The report documented three separate carcinomata across the patient's liver."
When doctors say 'carcinomata' instead of 'carcinomas', they're keeping a 2,000-year-old Greek tradition alive — Hippocrates himself named these crab-like cancers 'karkinos'.

Etymology of carcinomata
Carcinomata descends from the Greek karkinoma, meaning cancerous ulcer or tumour, formed from karkinos (crab, also the source of "cancer" via Latin). Greek physicians including Hippocrates applied the crab metaphor to tumours whose radiating extensions resembled a crab's legs. The term entered medical Latin as carcinoma and was adopted into English in the early modern period, retaining its Greek plural form alongside the anglicized carcinomas.
