Prostate Health Introduction |
|
Only
found in males, the prostate is a chestnut shaped
gland that surrounds the beginning of the
urethra in the urogenital system. Its main functions are to produce a
component of semen, to help eject
semen during ejaculation, and to help
prevent the backflow of urine from
the urethra. The prostate can
only be felt by rectal
examination; also known as a
digital rectal examination, or DRE. |
 |
In the U.S., a DRE is
considered standard within the
complete physical examinations performed on every man over the
age of 50, as well as in higher risk
populations. Prostate health is an
important component in all wellness
examinations and should be
monitored.
Prostate disease
is multi-factorial and many
disorders of the gland are still
unknown. Acute and chronic
prostatitis, benign prostatic
hypertrophy, and prostate
cancer are the most common
conditions seen in men.
-
Prostatitis
is one type of lower urinary tract
infection, which can become chronic
over time.
-
Acute
prostatitis is usually spread
via sexual activity and is more
commonly seen in younger men.
-
Chronic
prostatitis is usually
associated with a western
lifestyle, in which the patient is
inactive, obese, or eats a low
nutrient diet. It has been
estimated that half of all men
will have symptoms of chronic prostatitis at some point in their
lives. [1]
One of the most
common issues in the development of benign prostate hypertrophy (BPH)
and cancer is hormone dysfunction. Estrogens and dihydrotestosterone (DHT)
accumulate and inhibit the normal
cell death in the prostate, causing
cell accumulation and increasing the
size of the gland. It is common in
men past the fifth decade to have a
gradual decline in testosterone and
a rise in estrogen. However,
these normal characteristics also support higher than normal
levels of estrogen and promote prostate
disease. [2] Evaluating and
treating the endocrine (hormonal)
component of both conditions is
imperative to a healthy outcome.
BPH is a condition in
which there is an excessive growth
of prostatic cells. It is a benign
process and may be a normal part of
aging. [3] Recent studies have suggested that
80% of men over the age of 80 will
develop BPH. [4] Most men with BPH are asymptomatic, but some will develop symptoms that
affect urination and sexual
function.
BPH can be diagnosis by
DRE. The gland will be boggy
and enlarged. Symptom
evaluation is usually done with a
questionnaire that evaluates the
frequency and discomfort with
urination. Prostate specific
antigen (PSA), a blood serum
test used to measure the
inflammatory markers, should be
measured before a digital examination, as this may increase levels that
were previously normal.
-
Acute Prostatitis: fever, pain on
urination, low back pain, urinary
urgency and frequency
-
Chronic Prostatitis: fatigue, chronic
pain (perineal, testicular,
penile), sexual dysfunction, sense
of rectal fullness
-
BPH: urinary frequency, nocturia
(urination at night), urgency,
hesitancy, weak stream, straining
to void, incomplete sensation at
voiding [11]
-
Prostate Cancer: usually asymptomatic but
may
include all urinary symptoms seen
in benign prostatic hypertrophy

Prostate Cancer Statistics |
-
Prostate cancer
is the second most common cancer
in men in the United States. [5]
-
It is estimated to
affect approximately 1 in 6 men, but
diagnosis is uncommon before the age of 50. Approximately 70% of cancers are
now diagnosed with the monitoring
of PSA (prostate
specific antigen) levels. [6] However, PSA levels can be falsely
elevated and should not be
considered the only parameter
when making a diagnosis. [7] PSA levels between 4-10 ng/ml are
considered to be more treatable
than levels above
10ng/ml. [8]
-
In 2003, 220,900
men were diagnosed with
prostate cancer. 28,900
died from the disease.
-
Autopsy studies
show that 30% of men over the age
of 50 have evidence of prostate
cancer at death, even though it was
not the direct cause of death. [9]
-
Chinese men at
autopsy have the same rates of
prostate cancer as American men
but do not have the same mortality
rates. [10] It can be hypothesized then that
cancer is common to many, but only
clinically evident and aggressive
in some populations, perhaps due
to certain dietary and lifestyle choices.
