Prostate Fact Sheet
What is
the Prostate?
The prostate is an organ found in the male
reproductive system. Its main role is to produce fluid that protects and
feeds sperm.
Where is
the prostate?
The prostate is about the size of a walnut and
shaped like a doughnut. It sits underneath the bladder and surrounds the
top part of the urethra, the tube which urine passes through on its way
from the bladder to the penis.
How it
changes with age.
The prostate relies on the male sex hormone,
testosterone to grow. At puberty, when testosterone levels increase, the
prostate grows 8 times in size and then doubles in size between the ages
of 21 to 50. From 50 to 80 years of age the prostate will double again in
size.
Benign
Prostatic Hyperplasia (BPH)
BPH is a non-cancerous enlargement
of the prostate gland. It is common for all men and usually starts around
the age of 40.
Prostate
Cancer.
Prostate cancer is suspected if there is an abnormal
blood test (PSA) and/or rectal examination (DRE result). Caught at an
early stage, there is a good chance it can be cured. The causes of
prostate cancer are largely unknown. It is clear that the chances of
developing prostate cancer increases with men over 50 years of age. Close
relatives of men who have prostate cancer are also more likely to be
affected.
Symptoms
for BPH or Prostate Cancer
The symptoms for BPH or Prostate
cancer are the same.
A number of men have no symptoms. Men who do have
symptoms usually find there are noticeable changes in urination.
Some
symptoms are;
difficulty in starting to pass urine
weak and poorly
directed stream of urine
dribbling of urine before and after
urinating
a need to get up several times during the night to
urinate
a feeling that the bladder is not completely empty
rarely
blood is in the urine
How is
BPH or Prostate Cancer diagnosed?
It is diagnosed by a physical
examination by a doctor (DRE), PSA test, urine test, biopsy or
scan.
Digital rectal examination (DRE)
The doctor will insert a
finger into your rectum; tumours can often be felt by this method. Even
though you might feel embarrassed, this procedure could save your
life.
PSA blood
test
The doctor will take a sample of your blood which will be
tested for the amount of prostate-specific antigen (PSA). PSA plays an
important part in the early detection of prostate cancer. A high PSA
reading may indicate prostate cancer; however it may also indicate other
prostate disease such as BPH as this test is not cancer specific.
Urine
test
Urine is tested to look for blood or infection.
Biopsy
The urologist may perform a
prostatic biopsy (remove a small piece of tissue from the prostate).
Biopsies can be uncomfortable and you may be given a mild sedative or
local anaesthetic. This sample is than checked by a pathologist, if cancer
is detected than it is graded as to how quickly your cancer is likely to
progress.
Scan
This is to establish if the
cancer has spread to the bones.
Sexual
Dysfunction & Radical Prostatectomy
Erectile Dysfunction is
common after a radical prostatectomy. Urologists, where possible, will
attempt to perform nerve sparing surgery in an attempt to reduce erectile
dysfunction. Erectile dysfunction treatments have proven to be effective.
There is some debate and some supportive research that early erectile
dysfunction treatment, within the first two mouths after surgery, is of
better benefit to the return of penile erections. These treatments maybe
oral tablets, injections, penile vacuum pump.
After a radical
prostatectomy it is common for the man to experience absence of
ejaculation, although he usually still experiences orgasm. Some men report
some degree of orgasmic pain interfering with sexual intimacy. The penis
may also appear shorter.
Partners may express concern and worry that
sexual activity could be harmful for their partner. They may also feel
frustrated that after the shock of their partner being treated for cancer
they now have to live with sexual dysfunction. It is also common for
partners to feel that they should “be happy their partner has been saved”.
The time after life saving surgery can be confusing and changing, from
stressful to intimate. Partners need to remember that they and their
partner have gone through an uncertain time, which has involved visits to
specialist, hospitalisation of their partner, separation from their
partner and dealing with issues around death. Some relationships grow
stronger, other may grow apart. Professional support is available for men
and their partners.
Concerned
about your prostate?
If you have any concerns about your
prostate, regardless of your age, discuss this with your doctor. Your
doctor may refer you to a urologist (genital specialist) when;
-
your
prostate is abnormally large or on examination your prostate has an
unusual texture
-
you experience persistent urine frequency
-
you have
an elevated PSA and/or abnormal DRE result.
