Gallbladder and bile duct cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Gallbladder cancer may result from a complication of gallstones. However, this inference rests on circumstantial evidence from postmortem examinations: 60% to 90% of gallbladder cancer patients also have gallstones, but postmortem data from patients with gallstones show gallbladder cancer in only 0.5%.
The predominant tissue type in gallbladder cancer is adenocarcinoma, 85% to 95%; squamous cell, 5% to 15%. Mixed-tissue types are rare.
Lymph node metastasis is present in 25% to 70% of patients at diagnosis. Direct extension to the liver is common (in 46% to 89%); direct extension to both the cystic and the common bile ducts, stomach, colon, duodenum, and jejunum also occurs and produces obstructions. Metastasis also spreads by portal or hepatic veins to the peritoneum, ovaries, and lower lung lobes.
The cause of extrahepatic bile duct cancer isn't known; however, statistics report an unexplained increased incidence of this cancer in patients with ulcerative colitis. This association may be due to a common cause — perhaps an immune mechanism, or chronic use of certain drugs by the colitis patient.
Extrahepatic bile duct cancer is the cause of approximately 3% of all cancer deaths in the United States. It occurs in both males and females (incidence is slightly higher in males) between ages 60 and 70. The usual site is at the bifurcation in the common duct. Cancer at the distal end of the common duct is commonly confused with cancer of the pancreas. Characteristically, metastatic spread occurs to local lymph nodes, the liver, lungs, and the peritoneum.

Malignant spinal neoplasms:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Primary tumors of the spinal cord may be extramedullary (occurring outside the spinal cord) or intramedullary (occurring within the cord itself). Extramedullary tumors may be intradural (meningiomas and schwannomas), which account for 60% of all primary malignant spinal cord neoplasms, or extradural (metastatic tumors from breasts, lungs, prostate, leukemia, or lymphomas), which account for 25% of these malignant neoplasms.
Intramedullary tumors, or gliomas (astrocytomas or ependymomas), are comparatively rare, accounting for only about 10%. In children, they're low-grade astrocytomas.
Spinal cord tumors are rare compared with intracranial tumors (ratio of 1:4). They occur equally in men and women, with the exception of meningiomas, which occur mostly in women. Spinal cord tumors can occur anywhere along the length of the cord or its roots.

Bladder cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Certain environmental carcinogens, such as 2-naphthylamine, benzidine, tobacco, and nitrates, predispose people to transitional cell tumors. Thus, workers in certain industries (rubber workers, weavers and leather finishers, aniline dye workers, hair-dressers, petroleum workers, and spray painters) are at high risk for such tumors. The period between exposure to the carcinogen and development of symptoms is about 18 years.
Squamous cell cancer of the bladder is most common in geographic areas where schistosomiasis is endemic. It's also associated with chronic bladder irritation and infection (for example, from renal calculi, indwelling urinary catheters, and cystitis caused by cyclophosphamide).
Bladder tumors are most prevalent in men older than age 50 and are more common in densely populated industrial areas.

About prevalence and incidence statistics:
The term 'prevalence' of Gall Bladder Cancer usually refers to the estimated population
of people who are managing Gall Bladder Cancer at any given time.
The term 'incidence' of Gall Bladder Cancer refers to the annual diagnosis rate,
or the number of new cases of Gall Bladder Cancer diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
