Answer
(4) Malignant tumours of the skin or mucous membrane
Solution
Malignant tumours (cancers) are named by the tissue in which they arise.
⇒ Carcinomas arise from epithelial tissue, i.e., the skin and the mucous membranes lining body cavities and glands.
⇒ Sarcomas arise from connective tissue (bone, cartilage, muscle); leukaemias and lymphomas arise from blood-forming tissue.
∴ Carcinoma refers to malignant tumours of the skin or mucous membrane.
