Androgens: Male hormones, such as testosterone.
Antiandrogens: Medications that block the testosterone
receptor.
Atrophy: Wasting away or shrinkage.
B
Biopsy: The removal of a small piece of tissue, which
is then examined under a microscope.
Bladder: A hollow organ that holds urine.
C
Cancer: A general term for a large group of diseases where
a lack of controls on cell growth and division exists.
Cancer cells: Cells that grow and multiply abnormally
and can spread to other parts of the body.
Chemotherapy: Treatment with drugs intended to kill
cancer cells.
Clinical trials: Studies designed to test new
ways to prevent or manage disease or its symptoms.
Combination therapy: When a doctor suggests
combining treatments for maximum effect, such as radiation therapy combined with
hormonal therapy or LHRH agonist combined with an antiandrogen.
D
Diagnose: Identify a disease by its signs and symptoms
and then confirm with tests.
Digital Rectal Exam (DRE): A procedure
in which the doctor inserts a gloved finger into the rectum to examine the rectum
and the prostate gland for signs of disease.
E
Erectile dysfunction: The inability to have
or maintain an erection.
F
Fatigue: Extreme tiredness.
G
Gastroenteritis: Inflammation of the stomach
and intestines.
Gleason Score: A score (2-10) that helps doctors
determine how aggressive prostate cancer is.
Gynecomastia: Swelling or enlargement of the breast.
H
Hormonal therapy: The use of medications or
surgical removal of the endocrine glands to control hormone sensitive disease.
Hormones: Body chemicals secreted by glands that circulate
in the bloodstream and produce specific effects on target organs and tissues, often
distant from the site of their production.

Incontinence: The inability to control urine flow.
Infertility: The inability to produce viable sperm
or eggs.
L
LHRH Agonist: An injectable substance which resembles

Lymph nodes: Small glands that release cells to defend
the body against harmful foreign particles.
M
Malaise: A nonspecific discomfort or feeling of uneasiness.
Male hormones: Substances, such as testosterone,

Metastasis: The spread of cancer cells to areas of

O
Orchiectomy: Surgical removal of the testicles.
P
Prostate cancer: Cancer of the prostate gland.
Prostate cancer can also spread to other parts of the body, such as lymph nodes,
bone, and seminal vesicles.
Prostate gland: A male gland, located between
the bladder and the penis, which surrounds the urethra.
Prostate-specific antigen: A substance
produced by prostate cells.
PSA Level blood test: A blood test used in the
detection and management of prostate disease.
Prostatectomy: Surgical removal of the prostate
(see "Radical Prostatectomy").
R
Radiation therapy: The use of directed high-energy
x-rays to kill cancer cells.
Radical prostatectomy: Surgery to remove
the entire prostate gland along with the nearby tissue such as the seminal vesicles.
(see "Prostatectomy").
Rectum: The final section of the intestines at the anus.
S
Semen: The thick, whitish fluid released through the penis
during orgasm. The prostate makes substances that are in semen.
Seminal vesicles: A pair of glands, near the
prostate, that add substances to semen.
Sperm: Male reproductive cells, produced in the testicles.
Staging: An evaluation of the extent of disease that
provides the basis for making treatment recommendations.
T
Testes (Testicles): The pair of egg-shaped glands contained
in the scrotum. They produce sperm and testosterone.
Testosterone: Stimulates a man's sexual activity
and the growth of the sex organs, including the prostate.
Transrectal Ultrasound (TRUS): The use
of sound waves to visualize the prostate.
U
Urethra: The duct that carries urine from the bladder.
W
