Gall bladder cancer
Cancer of the gall bladder is extremely uncommon. Gall stones are present in about 75% of cases, but there is no definite causal relationship. Dysplasia and carcinoma in situ are the precursors of most invasive carcinomas of the gallbladder (mostly adenocarcinomas). This type of cancer is largely found in the elderly, with a female predominance (1:3). Since most cases are diagnosed late and are unresectable, prognosis is poor.
