Tlhaloso ea Lihlopha tsa Epithelial
Lisele tsa epithelial li hlalosoa e le lisele kapa mahlaseli a epithelium - e leng lesela le lenyenyane la mesifa e koahelang kapa e tsamaeang ka holim'a li-tubes kapa makhethe ka har'a 'mele. Ha lisele tsa epithelial li fetoha tse bolaeang (e ba kankere) li etsa li-tumor tseo ho thoeng ke li-carcinoma. Hoo e ka bang 80% ea kankere ea 'meleng oa motho ke li-carcinoma.
