Penile cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of penile cancer is unknown; however, it's generally associated with poor personal hygiene and with phimosis in uncircumcised men. This may account for the low incidence among Jews, Muslims, and people of other cultures that practice circumcision at birth or shortly thereafter. (Incidence isn't decreased in cultures that practice circumcision at a later date.) Early circumcision seems to prevent penile cancer by allowing for better personal hygiene and minimizing inflammatory (and commonly premalignant) lesions of the glans and prepuce. Such lesions include:
❑leukoplakia — inflammation, with thickened patches that may fissure
❑balanitis — inflammation of the penis associated with phimosis
❑erythroplasia of Queyrat — squamous cell cancer in situ; velvety, erythematous lesion that becomes scaly and ulcerative
❑penile horn — scaly, horn-shaped growth.
Penile cancer rarely affects circumcised men in modern cultures; when it does occur, it's usually in men who are older than age 50.

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 Penis Cancer usually refers to the estimated population
of people who are managing Penis Cancer at any given time.
The term 'incidence' of Penis Cancer refers to the annual diagnosis rate,
or the number of new cases of Penis 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.
For more information see about prevalence and incidence statistics.
