The term **癌细胞** (ái xìbāo), meaning "cancer cell," is formed through a logical and descriptive compound word structure in Chinese. It combines the character **癌** (ái), which itself is a pictophonetic character containing the "sickness" radical (疒) to denote a disease, specifically "cancer," with the word **细胞** (xìbāo), meaning "cell." Therefore, the compound directly and transparently signifies a "cancerous cell" or a "cell of cancer," where the modifier (**癌**) specifies the pathological type of the noun (**细胞**). This formation is typical of modern Chinese scientific terminology, creating precise meanings through the direct combination of existing semantic units.
