Relating to a type of cancer that begins in the skin or in tissues that line or cover internal organs.
The doctor diagnosed her with a carcinomatous condition that required immediate treatment.
Carcinomatous is formed from "carcinoma" (from Greek "karkinoma", meaning cancer) and the suffix "-tous" (meaning characterized by or full of). The word describes something that is characterized by or related to cancerous tumors.
Think of 'carcinoma' which means cancer, and '-tous' suggests being full of or characterized by. This helps you remember that 'carcinomatous' refers to something related to cancer.
