| Prostate cancer is rare in
Asia. However, prostate cancer is the second most common cause of
cancer deaths in American men older than 55 years of age. About
one in five men in the United States develop prostate cancer.
According to the 2002 statistical reports of the American Cancer
Society, it is estimated that 189,000 new cases of prostate and
30,200 deaths occur annually.
Prostate cancer rates are twice as high in African American men
than in Caucasian men, and African American men are more likely to
die of prostate cancer than men are in any other racial or ethnic
group.
To address this issue, experts have assessed knowledge of
prostate cancer and the use of prostate cancer screening services
among 108 African American men.
Results showed how men were unable to answer most of the 21
questions on the test with more than 70% accuracy, although
individuals younger than 40 years of age were more knowledgeable
than older men.
Despite their increased risk for prostate cancer, only 47% of
the men in the sample who were 40 years or older had prostate
cancer screening as part of their annual physical examination.
Knowledge abut prostate cancer was found to be negatively
correlated with education, income, and age. A culturally sensitive
promotional campaign has been identified as an important strategy
to increase awareness of the racial disparities in the incidence
of prostate cancer and mortality rates.
Risk factors for prostate cancer include increasing age: the
incidence of prostate cancer multiplies fast past the age of 50
years, and more than 70% of cases occur in men who are more than
65 years of age.
African American men have the highest incidence of prostate
cancer in the world. Prostate cancer is common in the United
States and northwestern Europe but is rare in Asia, Africa,
Central America, and South America.
A familial predisposition may occur in 5% to 10% of cases of
prostate cancer. If you have a brother or a father with prostate
cancer, chances are, your risk is doubled. The risk increases
further if several relatives have had prostate cancer.
Furthermore, research shows that a diet high in red meat and
fat increases the risk for prostate cancer. Large-scale studies
are in progress to determine if prostate cancer can be prevented
by use of selected supplements or “finasteride.”
Clinical Symptoms
Cancer of the prostate in its early stages rarely produces
symptoms. The symptoms that develop from urinary obstruction occur
late in the disease.
Prostate cancer tends to vary in its course. If the neoplasm is
large enough to encroach on the bladder neck, signs and symptoms
of urinary obstruction occur; difficulty and frequency of
urination, urinary retention, and decreased size and in the
urinary stream.
Other symptoms may include blood in the urine or semen and
painful ejaculation. Hematuria may result if the cancer invades
the urethra or bladder, or both. Prostate cancer can metastasize
to bone and lymph nodes.
Symptoms related to metastases include backache, hip pain,
perineal and rectal discomfort, anemia, weight loss, weakness,
nausea, and oliguria or decreased urine output. Unfortunately,
these symptoms may be the first indications of prostate cancer.
Treatment
Treatment is based on the stage of the disease and the
patient’s age and symptoms. However, since most cases of prostate
cancer rarely produce symptoms, it is better to render some
dietary modifications to help men pause the growth and development
of the disease and stop it from becoming acute.
Hence, to prevent prostate cancer, proper nutrition and sound
health regimen is needed.
