History of the prostate glandHISTORY OF THE PROSTATE GLAND
The prostate is a gland that is located just underneath the
bladder. It surrounds the urethra through which a man
urinates. The prostate gland is therefore vital to proper
bladder control and urine flow-rate. The prostate is also
essential for normal sexual function. It is the gland of
ejaculation, supplying 95% of the seminal fluid and the
power to push it through the urethra and out of the penis.
The normal prostate in an adult man is about the size of a
walnut. Its size often increases over time, however,
particulary once a man gets beyond age 40. Because the
urethra runs right through the middle of it, a growth spurt
of the prostate will squeeze the urethra and begin to choke
off the urinary flow. This can effect the ablility to
urinate and perform sexually.
SYMPTOMS OF PROSTATE CANCER
Prostate cancer occurs when some of the cells that
make up the prostate gland escape from the normal controls
on their growth and start to divide, grow and spread in an
uncontolled manner. At first the growth of the cancer
occurs very slowly and is usually limited within the
prostate gland. Later on in the course of the illness, the
prostate gland cells can spread around the body,
particulary to the bones where they can paues pain and
disability. Estimates show that the cancer may have been
growing in some men for up to 10 yearsbefore it causes
symptoms and is diagnosed. Some men develop symptoms
whereas others do not. In those who that do, the following
symptoms are commonly found:...
