Black Men at Greater Risk of
Aggressive Prostate Tumors |
WEDNESDAY, June 2 (HealthDay News)
-- Black men are already known to be
at higher risk of developing
prostate cancer than white men, but
now a new study reports that they
also appear to be more likely to
develop aggressive forms of the
disease.
Researchers analyzed biopsies from
131 men -- 67 blacks and 64 whites
-- whose prostates were removed at
the Durham Veterans Affairs Medical
Center in North Carolina. The
investigators found signs that the
black men had more aggressive forms
of prostate cancer.
The findings are scheduled to be
released Wednesday at American
Urological Association annual
meeting in San Francisco.
"African-American men are more than
twice as likely to develop prostate
cancer, and these data show tumors
may be more aggressive in this
population," Dr. Anthony Y. Smith, a
spokesman for the association, said
in a news release. "African-American
men should be especially vigilant
about their prostate health and talk
with their physicians about prostate
cancer testing starting at age 40." |

Size of Prostate Tumor Linked to
Patients' Weight |
Tumor size among prostate cancer
patients appears to be linked to
patient weight, with heavier men
having larger tumors, a new study
reveals.
The finding stems from work
involving more than 3,300 prostate
cancer patients with an average age
of 60 who underwent surgery between
2001 and 2007 to remove a malignant
prostate gland and surrounding
tissue.
"As the patient's body mass index
[BMI] increased, the tumor volume
increased synchronously," Dr. Nilesh
Patil, from the department of
radiology at the Henry Ford
Hospital's Vattikuti Urology
Institute in Detroit, said in a news
release. "Based on our results, we
believe having a larger percentage
of tumor volume may be contributing
to the aggressive nature of the
disease in men with a higher BMI."
BMI is a measurement of body fat
that takes into account a person's
weight and height. In the study, BMI
scores ranged from 24.9 or less for
normal to underweight individuals,
to 40 or higher for morbidly obese
individuals, the team noted.
Patil's team is slated to present
the findings Wednesday in San
Francisco at the American Urology
Association annual meeting.
The authors noted that prior
research had already established
that aggressive prostate cancer was
linked to having a higher BMI.
To explore whether or not the
cancer-BMI association translated
into bigger tumor size, the research
team weighed and compared tumors
that had been removed from the
patients.
The authors found that in every BMI
category -- underweight, normal,
overweight, obese and morbidly obese
-- tumor size correlated directly
with patient weight, with
lower-weight patients having smaller
tumors and higher-weight patients
having larger tumors. |

Prostate Tumor Symptoms |
Because prostate cancer is usually
so slow growing, it rarely causes
physical symptoms until quite
advanced. Even then, the typical
symptoms are non-specific and easily
confused with symptoms from other
conditions, which are either not
dangerous or less worrisome than
prostate cancer.
Urinary Symptoms
Urinary problems, such as an
intermittent or weakened stream or
increasing frequency, may be due to
a prostate tumor. They also could
caused by overgrowth of the prostate
gland or by a bacterial or viral
infection in the urinary system.
Blood in the Urine
Bloody urine can come from many
causes including benign enlargement
of the prostate, broken blood
vessels in the urinary system,
kidney or bladder stones or cancer.
A doctor should evaluate any
occurrence of this.
Blood in Semen
Usually this is not a symptom of a
prostate tumor. Rather it can come
from irritation of the urinary
tract, straining during sexual
activity or even from a bowel
movement. However, a doctor should
check this symptom.
Swelling in the Lower Extremities
If prostate cancer spreads to the
nearby lymph nodes, it may cause
swelling in the legs.
Pain
A prostate tumor that has entered an
advanced stage can cause bone pain
in the lower back, hip or pelvis.

Prostate Cancer Tumor Grading |
Prostate cancer involves abnormal
cell growth in the prostate, which
is the walnut-shaped gland in men
that is responsible for producing
seminal fluid. Prostate cancer is
the most common kind of cancer in
males, affecting approximately one
in every six men in the U.S.,
according to the Mayo Clinic.
Gleason Score
The prostate cancer tumor grading
method most commonly used is the
Gleason system, which is named after
the pathologist who created it. Dr.
Donald Gleason devised this staging
system to evaluate the prognosis of
males with prostate cancer.
Features
The Gleason system grades prostate
cancer cells on a scale from Grade 2
to Grade 10. The final grade is
derived by assigning a grade to the
two largest cancerous areas of the
prostate tissue samples and adding
the two grades.
Significance
Higher Gleason scores mean the
prostate cancer tumor is aggressive
and poorly differentiated. Lower
scores mean the prostate tumor is
less aggressive and
well-differentiated.
Diagnosis
Prostate tissue is obtained through
a biopsy of the prostate. Most males
with prostate cancer have Grade 5 to
Grade 7 tumors.
Considerations
Prostate tumors rating Grade 2 to
Grade 4 typically don't shorten a
patient's lifespan. Tumors with
grades of 5 to 7 can shorten a man's
life by four or five years, while
tumors Grade 8 to Grade 10 can take
six to eight years off a patient's
life.
Warnings
Prostate cancer tumor grading isn't
an exact science. Tumors might be
missed in the prostate biopsy and
doctors' grades can vary. |

Non invasive treatment of benign
prostate tumor case |
Once the prostate
swelling is diagnosed as
a benign prostate tumor,
the treatment options
open up to include
several approaches and
methods of treatment
but, if the prostate
swelling is diagnosed as
prostate cancer then the
only solution is to
totally remove the
prostate gland.
In cases of benign
prostate tumor, the
doctor can try several
lines of treatment
before he goes for the
surgical approaches.
Although the surgical
approaches are proven to
be of excellent results
but it has a major side
effect which is that the
surgical approach cause
male impotence.
Because of this
particular and sensitive
reason, specialists tend
to postpone the surgical
treatment as long as
they can. And with the
discovery of new methods
of treatments the
choices are wider and
with more options
included.
Apart from the herbal
treatment that turned
out to be a scam and the
medical treatments that
take anywhere between
three to six months to
see a significant
improvement in the case,
there are new methods
that resemble the effect
of surgery but without
the side effects.
The first method is
called transurethral
needle ablation or
(TUNA). This method
depends on applying a
radio wave frequency to
the pelvic region
targeting the prostate
gland to cause shrinkage
through the radio waves.
The transurethral
microwave thermotherapy
is another approach that
depend on waves too but
this time it depend on
the thermal effect of
the waves instead of
depending of the pulses
itself like in case of
radio wave treatment.
Transurethral electro
vaporization is one of
the most recent
techniques used to treat
prostate by inducing a
very little electric
current. Water induced
thermotherapy is another
method of treatment
depending on the effect
of heat on the shrinkage
of prostate
Finally, there are now
trials to include the
laser in the treatment
of prostate swelling but
most of these treatments
are still developing and
did not reach the
required level of
success to replace the
surgical techniques
completely but they
constitute a good
replacement in mild
cases where the surgical
opening or even the
endoscopy are not
necessary.
People always tend to
avoid surgery at any
cost because they are
always afraid of the
complications like virus
transmission and other
complications and not to
mention the potential of
occurrence of impotence
as a side effect of the
surgery. But even with
all of these debates and
side effects, surgery is
still number one choice
in cases of complete
urine stasis or urethral
stones because these
cases need immediate
response before it
propagate into more
serious complications
