| Doctors,
Researchers Should Stress Cancer Prevention
Although
doctors and researchers have had a number of successes in the diagnosis
and treatment of cancer, we need to stress cancer prevention.
Prevention is the key to reducing cancer, but only a small percent
of the resources devoted to cancer are used to encourage prevention.
For example, many sources give information on cancer screening and
treatment, but scant information is available on how to avoid getting
sick.
A case in point is prostate cancer. In Illinois, almost 10,000 new
cases of prostate cancer are diagnosed each year. Many people diagnosed
will have surgery, radiation and other procedures. Yet, a significant
percentage of these cancers might be preventable - possibly by something
as simple as taking a dietary supplement.
Prostate cancer is more common among African-Americans and men living
in northern climates. There is a straightforward connection between
these two groups that might help to prevent prostate cancer: vitamin
D.
Vitamin D is a fat-soluble vitamin that helps deposit calcium in
the bone. Interestingly, vitamin D needs sunlight to become activated.
Increased melatonin in the skin of African-Americans reduces the
activation of vitamin D. Those living in northern climates have
less overall sun exposure (and vitamin D activation).
A recent study in the medical news journal Internal Medicine World
Report concluded that higher blood levels of activated vitamin D
were associated with a considerably reduced risk of prostate cancer.
This data came from the Physicians Health Study, which tracked 1,082
physicians who developed and later died from prostate cancer and
compared them to 1,701 other men of the same age.
What was discovered was that those with lower levels of vitamin
D were at double the risk of developing prostate cancer and had
three to four times the risk of contracting aggressive prostate
cancer compared to the other men. Indeed, those with vitamin D levels
above normal had a 45 percent reduction in the risk of ever developing
prostate cancer. Men living in Asian countries, where the diet is
rich in fish, have the highest levels of vitamin D and lowest levels
of prostate cancer in the world.
Considering the thousands of dollars in medical costs and personal
trauma resulting from prostate cancer, it is encouraging to think
that up to 45 percent of new cases could be prevented for pennies
a day.
We know that vitamin D affects cell growth and can cause cancer
cell death. Recent research has demonstrated that vitamin D might
act at the DNA level, promoting the production of natural anti-cancer
compounds like tumor necrosis factor (TNF). Higher levels of serum
vitamin D might promote higher levels of natural anti-cancer compounds
like TNF. Lower vitamin D levels might do the opposite.
The recommended daily dose of vitamin D is 400 IU. Higher daily
doses (possible as little as 800 IU/day) might be required for the
most benefits. Although fish, fortified milk and egg yolk are sources
of vitamin D, multivitamins and dietary supplements might be more
convenient.
Billions have been spent in research, diagnosis and treatment of
cancer. Hospitals and medical centers nationwide emphasize innovations
and cutting edge therapies, but few stress prevention - and prevention
is where we really need to be. Prostate cancer should not be an
issue in the US, it is very easy to prevent.
