BPH - Symptoms and Treatment
At 50 years of age and over, one man in five will suffer from a prostate related
problem. So just what happens at this time of life? Let's take a look.
After about 50, the prostate often begins to enlarge: the cells multiply to
form a benign tumor, known as an adenoma. This is normally known simply as
BPH, a shortened form of Benign Prostatic Hyperplasia or Benign Prostatic Hypertrophy.
BPH develops in the central region of the prostate.
This hypertrophy extends through all three prostatic tissues - glandular (adenoma),
fibrous (fibroid), and muscular (myoma) – resulting in what is known
as adenofibromyoma. This is in fact similar to uterine fibroids found in women.
BPH is not cancerous and does not become cancerous.
It is nevertheless still possible to find some cancerous cells inside a prostatic
adenoma. The two diseases are therefore related, although under no circumstances
will adenoma transform into cancer.
In the western, industrialized world, BPH develops in about 10% of men of
30 years old and above, reaching 50% of men between the ages of 50 and 80.
On the other hand, BPH is rarely found in Asia.
Causes of BPH
The origins of BPH aren't precisely known. However the involvement of
male hormones (androgens) is indisputable, since BPH never arises in men castrated
before reaching puberty, and castration can also cause regression of pre-existing
BPH. However, although there are several paths of investigation, the precise
involvement of androgens is still unknown.
Inside BPH cells are found increased concentrations of dihydrotestosterone (DHT) originating from the transformation of testosterone under the influence
of the enzyme 5-alpha-reductase. From a certain age, DHT favorizes increased
cellular development, leading to hypertropy of the prostate gland.
Other studies claim female hormones (estrogens) as the cause, but a single
hormonal hypothesis on its own can't explain everything.
Growth Factors
Linked to the male androgen hormones, growth factors, called IGF (insulin-like
growth factors), also seem to play an important role. They are secreted by
certain prostate cells and work particularly on the multiplication, determination
and survival of the cells. Several growth factors exist although we still don't
know how the come to deregulate men over a certain age.
A Link with Sexual Activity?
Contrary to what one sometimes thinks, there is no link between an enlarged
prostate and the frequence of sexual activity. For centuries prostate problems
were linked with a dissolute sexual life (just as with venerial disease). These
are simply "old wives tales".
The Progress of BPH
BPH begins at the microscopic level, gradually becoming macroscopic and palpable
to a rectal examination. The size of BPH increases at a regular pace and can
double in volume in about 10 years. But it's important to note that there
is no direct link between the size of the prostate and the presence (or intensity)
of urinary problems. In other words, just because you have an enlarged prostate,
it doesn't follow that you will also suffer with urinary problems.
A large number of BPHs arise without obvious symptoms. It's possible
to have a prostate only slightly enlarged, about 20-30g, which causes severe
problems. The reverse is also true – a very large prostate of say 300g
might cause minimum trouble.
The Onset of Urinary Problems
Urinary problems tend to be variable, with periods of major discomfort and
then apparent sudden relief. But in general problems tend to increase as the
years pass.
Problems also vary with diet, what you drink, physical activity, and the seasons.
Problems tend to be greater during Autumn and Winter.
BPH - Not Really an Illness
Prostatic adenoma arises with age. So long as the prostate, even a large
one, remain supple, all that's required is regular surveillance.
Between 50 and 60 years of age, surveying is recommended every two years.
Above 60, this is recommended annually. These tests enable the development
of the adenoma to be followed and to detect any potential complications early
on. They also permit the detection of any prostatic cancer at an early stage.
Such surveillance is recommended for men even with very mild symptoms without
any particular impact on their lives. In such cases it is possible to simply
live with it, whilst respecting certain simple hygiene rules. This certainly
isn't a "treatment", it's simply learning to live in
harmony with a few little urinary problems.
