二 分类
(1)上皮性,占95%以上,
其中乳头状瘤(2%),移行细胞癌(94%),原位癌(1%),鳞状细胞癌(2%),腺癌(1%)。
(2)非上皮性
B、classification:
(1)Superficial ,more than 95%,
approximately 2% of that are papillary cancer,94% are transitional cell cancer.
(2)invasive,

三 病因
内在的遗传因素和外在的环境因素,肿瘤发病是复杂的多种因素作用的结果。
C、 pathogeny
Heredity factor inside and environmental factor outside,which is complicated.

1、 遗传易感性:
膀胱肿瘤和性别年龄关系密切,发病率男性比女性高2~10倍;60岁以后发病率高,很少在40岁以前发病。
1 、 Heredity susceptibility:
the incidence of bladder cancer increases directly with age and sex, which increases in people after 60 years old and is 2-10 times as common in men as in women.

2. Risk factor:
there are environment, occupation, smoking, infection, calculus and so on.

3、 生物学特点:
对膀胱癌生物学行为的研究表明膀胱癌的发生是一个多阶段过程,包含了多种基因突变,这些突变又可被分为早期和晚期。
3. Biological characteristic:
it contains manifold gene mutation.
