Prostate cancer is a disease in which cancer develops in the prostate,
a gland in the male reproductive system. Cancer occurs when cells of
the prostate mutate and begin to multiply out of control. These cells
may spread (metastasize) from the prostate to other parts of the body,
especially the bones and lymph nodes. Prostate cancer can cause pain,
difficulty urinating, erectile dysfunction, and other symptoms.
Prostate cancer only occurs in men and develops most frequently in
individuals over fifty years old. It is the second most common type of
cancer in men and is responsible for more deaths than any cancer
except for lung cancer. Prostate cancer is most often discovered by
screening blood tests, such as the PSA (prostate specific antigen)
test or by physical examination of the prostate gland by a health care
provider. Prostate cancer can be treated with surgery, radiation
therapy, hormone therapy, occasionally chemotherapy, or some
combination of these. The age and underlying health of the man as well
as the extent of spread, appearance under the microscope, and response
of the cancer to initial treatment are important in determining the
outcome of the disease.

to be back in Eden, where doing nothing was not boring — it was
