a大多數感染可自行清除,但持續感染可導致疾1

感染某些高危型HPV, 如HPV 16和18,可導致 約90%子宮頸癌及 約90%肛門癌

低危型HPV 主要引致生殖器官濕疣(俗稱椰菜花) 超過90%椰菜花 由HPV 6及11引起。

大部分的HPV感染通常不會有病徵,

潛伏期可高達10年,更會人傳4

若無法自行清除,感染HPV到現在

仍然沒有針對性治療方法,

根據醫管局數據顯示, 在過去十年, 2 5 - 2 9 歲的子宮頸癌平均發病人數是 20-24歲的7倍,45-49歲女性更為確診 子宮頸癌數目的高6b

當子宮頸內細胞受到HPV的持續侵襲, 就可能導致細胞變異,引發子宮頸上皮內瘤 (CIN)。若CIN第3級得不到適當的治療, 10年內演變成癌的機會約40%7

本港平均每2-3日便有一位女士 因爲子宮頸癌離開最愛的家8c

b 2010-2019年十年來20-24歲的子宮頸癌平均新症數目為<1,而25-29歲為76

c 根據2019年資料顯示 子宮頸癌死亡個案為1628

病徵:肛門癌早期病徵與痔瘡相似,如有分泌物於股溝流出或肛門出血9一般人難以區分,以至延誤就10

治療方案:肛門癌可以透過肛門局 部/全切除手術、放射治療以及化學 藥物治療去治11 - 13若進行肛門切除手術或需造外置造口,或會影響日常生11

不論男女,肛門癌放射治療可能 引致不12

病徵:椰菜花可以潛伏2星期至8個 14椰菜花病徵為一個或多個結塊生長於生殖器官、生殖器官痕癢、排尿不尋常14-15

治療方案:椰菜花治療方法包括冷凍治療法、手術切除、燒灼治療14椰菜花難以斷尾,約4成患者至少復發116

本港男性椰菜花患者比女性高 2.8倍14a

其他疾病亦存風險:外陰癌及陰道1
