The pathology report noted 'fibroma,' but it is a benign tumor usually called 線維腫.
Standard kanji spelling for this medical term.
Mixed kanji-kana spelling; may be used when the kanji 癌 is considered difficult or in patient-facing contexts.
Compound of 繊維 (せんい, 'fiber') and 癌 (がん, 'cancer'), but despite the 癌 character, the term refers to a benign fibroma. The exact historical derivation is uncertain; it may be an older or variant term now largely replaced by 線維腫.
