Prostate Cancer
Awareness Can Save Lives
One of the most common cancers to be
diagnosed in men, prostate cancer has a good prognosis when diagnosed early.
Approximately 2.8 million men in the United States have prostate cancer.
Raising awareness of this type of cancer is key in being able to detect this
cancer early.
Definition
Prostate cancer begins in the
prostate, which is a walnut-shaped gland that is responsible for producing
seminal fluid. Some types of prostate cancer grow slowly and may need very
little treatment while other types grow quickly and aggressively.
Symptoms
Unfortunately, in its very early
stages prostate cancer has few symptoms. As the tumor grows, it begins to
affect the body. These signs include:
- trouble urinating
- blood in the semen
- decrease in force of urine
- erectile dysfunction
- pelvic pain
Doctors and scientists disagree on
when screening for prostate cancer should begin. Most recommend screening
beginning at the age of 50, with screening starting sooner for those who have a
history of prostate symptoms.
Diagnosis
A digital rectal exam (DRE) can be a
useful tool in screening for prostate cancer. A doctor will insert a gloved,
lubricated finger into the rectum. The rectum is adjacent to the prostate and
abnormalities in the size, shape or texture can indicate the need for further
testing.
A blood test for the presence of
prostate-specific antigen (PSA) may also be done. Normally a small amount of
PSA is in the blood of healthy men; a higher amount can indicate abnormalities
with the prostate. The PSA combined with the DRE test has the highest rate of
discovering prostate cancer in its early stages.
If abnormalities are found during
screening, an ultrasound and a prostate tissue biopsy will be done to determine
if the patient has prostate cancer.
Treatment
If the cancer is slow-growing, no
treatment may be necessary. Doctors will monitor the tumor to determine if it’s
growing and if further action needs to be taken.
In cancers that are more aggressive,
radiation to kill the cancer cells, hormone therapy to slow the production of
testosterone or surgery to remove the prostate may be necessary.
Prognosis
The five-year survival rate for
prostate cancer is nearly 100 percent. Ten years after diagnosis, almost 99
percent of patients are still living. After 15 years, this number drops to 94
percent.
These survival rates drop
considerably if the cancer is found in a later stage, making early detection
critical in saving lives.
