Prevalence and Incidence of Liver cancer
Liver cancer: Rare Disease
Liver cancer is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Liver cancer, or a subtype of Liver cancer,
affects less than 200,000 people in the US population.

Colorectal cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of colorectal cancer is unknown, but studies showing concentration in areas of higher economic development suggest a relationship to diet (excess saturated animal fat). Other factors that magnify the risk of developing colorectal cancer include:
❑other diseases of the digestive tract
❑age (older than age 40)
❑history of ulcerative colitis (average interval before onset of cancer is 11 to 17 years)
❑familial polyposis (cancer almost always develops by age 50).
There are more than 130,000 cases of colorectal cancer diagnosed in the United States each year. It's the second-leading cause of cancer-related death, accounting for more than 50,000 per year. However, in almost all cases, it's treatable if caught early by colonoscopy.

Liver cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The immediate cause of liver cancer is unknown, but it may be a congenital disease in children. Adult liver cancer may result from environmental exposure to carcinogens, such as the chemical compound aflatoxin (a mold that grows on rice and peanuts), thorium dioxide (a contrast medium formerly used in liver radiography), Senecio alkaloids, and possibly androgens and oral estrogens.
Roughly 30% to 70% of patients with hepatomas also have cirrhosis. (Hepatomas are 40 times more likely to develop in a cirrhotic liver than in a normal one.)
Whether cirrhosis is a premalignant state or alcohol and malnutrition predispose the liver to develop hepatomas is still unclear. Other risk factors are exposure to the hepatitis C virus and the hepatitis B virus.
Liver cancer accounts for roughly 1% of all cancers in the United States and for 10% to 50% in Africa and parts of Asia. Liver cancer is most prevalent in men (particularly men older than age 60), and incidence increases with age. It's rapidly fatal, usually within 6 months, from GI hemorrhage, progressive cachexia, hepatic failure, or metastasis.

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.

About prevalence and incidence statistics:
The term 'prevalence' of Liver cancer usually refers to the estimated population
of people who are managing Liver cancer at any given time.
The term 'incidence' of Liver cancer refers to the annual diagnosis rate,
or the number of new cases of Liver 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.
