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.

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.

Rectal polyps:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Formation of polyps results from unrestrained cell growth in the upper epithelium. Predisposing factors include heredity, age, infection, and diet.
Villous adenomas are most prevalent in men older than age 55; common polypoid adenomas, in white women between ages 45 and 60. Incidence in both sexes rises after age 70. Juvenile polyps usually occur among children younger than age 10 and are characterized by rectal bleeding.

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