Prostate Cancer Basics
Prostate Cancer |

Prostate cancer is a group of cancerous cells (a
malignant tumor) that begins most often in the outer
part of the prostate.
Prostate cancer
is the second
most common type of cancer in men in the
United States.
Skin cancer is the most common. Of
all the men who are diagnosed with
cancer each year,
more than one-fourth have prostate cancer.
Prostate Basics
The prostate is a
gland in a man's reproductive system. It makes and
stores seminal fluid, a milky fluid that nourishes
sperm. This fluid is released to form part of semen.
The prostate is
about the size of a walnut. It is located below the
urinary bladder and in front of the rectum. It
surrounds the upper part of the urethra, the tube
that empties urine from the bladder.
If the
prostate grows too large, the flow of urine can be
slowed or stopped.
To work properly,
the prostate needs
male hormones (androgens).
Male
hormones are responsible for male sex
characteristics. The main male hormone is
testosterone, which is made mainly by the
testicles.
Some male hormones are produced in small amounts by
the adrenal glands.
Early Symptoms of
Prostate Cancer
Early symptoms of prostate cancer are often
difficult to trace, as prostate cancer does not
cause unique symptoms. But prostate cancer can cause
any of these problems:
|
- A need to urinate frequently, especially at
night
- Difficulty starting urination or holding back
urine
- Inability to urinate
- Weak or interrupted flow of urine
- Painful or burning urination
|
- Difficulty in having an erection
- Painful ejaculation
- Blood in urine or semen
- Frequent pain or stiffness in the lower back,
hips, or upper thighs.

Any of the above listed "prostate
cancer symptoms" may be caused by
cancer or by other, less
serious health problems, such as BPH (Benign
Prostatic Hyperplasia) or an
infection. A man who has "prostate
cancer symptoms"
like these should see his doctor or a urologist (a
doctor who specializes in treating diseases of the
genitourinary system).
Check your
prostate regularly. Normally after shower is
the best time to check prostate, as a scrotum is fairly
relaxed then. When you gently grab one of your
prostates with your thumb and index finger, it
should be resilient but hard. Its surface
should be smooth. If you found any sign of
change, talk to your doctor about it.
The
Prostate Cancer Process
Cancer is a group
of many related diseases. These diseases begin in
cells, the body's basic unit of life. Cells have
many important functions throughout the body.
Normally, cells
grow and divide to form new cells in an orderly way.
They perform their functions for a while, and then
they die. This process helps keep the body healthy.
Sometimes,
however, cells do not die. Instead, they keep
dividing and creating new cells that the body does
not need. They form a mass of tissue, called a
growth or tumor.
Prostate tumors can be benign or malignant
Benign
tumors are not cancer. They can usually be
removed, and in most cases, they do not come back.
Cells from benign prostate tumors do not spread to other
parts of the body. Most important,
benign
tumors of the prostate are not a threat to life.
Benign prostatic
hyperplasia (BPH) is the abnormal growth of
benign prostate cells. In BPH, the prostate grows
larger and presses against the urethra and
bladder, interfering with the normal flow of
urine.
More than half of the men in the United
States between the ages of 60 and 70 and as many
as 90 percent between the ages of 70 and 90 have
symptoms of
BPH.
For some men, the symptoms may be severe enough to
require treatment.
Malignant tumors are cancer. Cells in these
tumors are abnormal. They divide without control
or order, and they do not die. They can invade and
damage nearby tissues and organs. Also,
cancer cells
can break away from a malignant tumor and enter
the bloodstream and
lymphatic system. This is
how cancer spreads from the original (primary)
cancer site to form new (secondary) tumors in
other organs. The spread of cancer is called
metastasis.
When
prostate
cancer
spreads (metastasizes) outside the
prostate,
cancer cells
are often found in nearby
lymph nodes. If
the cancer has
reached these nodes, it means that prostate cancer cells may
have spread to other parts of the body -- other
lymph nodes and
other organs, such as the
bones,
bladder, or rectum.
When
cancer spreads from its
original location to another part of the body, the
new tumor has the same kind of abnormal cells and
the same name as the primary tumor. For example,
if
prostate
cancer
spreads to the bones, the cancer cells in the
new tumor are prostate cancer cells. The
disease is metastatic prostate cancer; it is not
bone cancer.
