Most males as they get older have a subconscious fear - Prostate cancer!
Prostate problems are extremely common, something we men have
to live with. After all, our women are always telling us how lucky we are to be
men and not have to go through childbirth, so it’s probably only right and
equitable that there is a male downside. In fact this year in the United States,
almost 180,000 men will be told that they have prostate cancer. That’s 180,000
downsides.
With all our older friends getting prostate problems, does
this mean there is a rise in the incidence? Are our underpants too tight? One
reason for the ‘apparent’ increase is the fact that prostate cancer is a disease
of aging, and we are all living longer. The statistics show that by age 50,
almost 50 percent of American men will have microscopic signs of prostate
cancer. By age 75, almost 75 percent of men will have some cancerous changes in
their prostate glands. Do the maths. By 100 we’ve all got it!
So does this mean that life really ends at around 76?
Fortunately no. Most of these cancers stay within the prostate, producing no
signs or symptoms, or are so slow-growing, that they never become a serious
threat to health. The good news is you die of something else before the prostate
gets you! You die with it, rather than from it.
The real situation is that a much smaller number of men will
actually be treated for prostate cancer. About 16 percent of American men will
be diagnosed with prostate cancer during their lives; 8 percent will develop
significant symptoms; but only 3 percent will die of the disease. Put another
much more positive way, 97 percent won’t die from prostate cancer.
While prostate cancer can be ‘aggressive’, breaking out from
the prostate gland itself and attacking other tissues, including brain and bone,
fortunately this is the minority scenario. The great majority of prostate
cancers are slow growing, and it can be decades between the early diagnosis and
the cancer growing large enough to produce symptoms.
So let’s look at diagnosis and get the “blood test” out of
the way first. The blood test is called Prostate Specific Antigen, or PSA for
short (we medico’s love acronyms). Up till then we had another test called DRE
(digital rectal examination), which, quite frankly, was not all that popular. As
medical students, we were taught, “If you don’t put your finger in it, you’ll
put your foot in it!” Despite this, ‘buyer resistance’ was high, so when news
came through about a “blood test”, millions of men began rejoicing and the sale
of rubber gloves plummeted. Unfortunately, PSA is not a go/no-go test. A normal
range test doesn’t guarantee you haven’t got it, and an elevated result doesn’t
automatically mean that you are about to claim early on your life insurance (or
your dependants, anyway).
However, there is good news. We are becoming smarter with the
PSA test. Elevated PSA levels in the blood correlate roughly with the volume of
cancer in the prostate, with the stage and grade of the tumor, and with the
presence or absence of cancer metastases or growths in other tissues. Serial PSA
examinations can also show the rate of this growth, and the rate of increase is
very significant.
Like many other cancers, prostate cancer can only be fully
diagnosed and ‘staged’ by microscopic analysis. ‘Staging’ has four main grades.
Stage I cannot be felt and is diagnosed through pathological testing. Stage II
can be felt, but it is confined to the prostate. Stage III is coming out of the
gland and Stage IV has grown into nearby tissues.
This is where you need to discuss your options with your
doctor. If you are a young man with stage IV, then you have to make up your mind
quickly. But if you are 75 with stage I or II, then you have more time, as you
will most likely die of other causes before the prostate cancer gets you. For
these people, “Watch and Wait” has much going for it, but you must be prepared
to get to know your urologist.
