Convincing individuals, especially those over 50 years of age, to
undergo regular colonoscopies would certainly result in more and
earlier diagnoses of this dreaded disease. Scientists and
researchers are doing everything possible to reduce the fear of tests
for colon cancer, including developing methods like the “virtual
colonoscopy”, which are less intrusive and cause less discomfort.
Obviously, early detection is of the utmost importance, but even those
who haven’t undergone tests for colon cancer can take some time to
determine their risk factors. Because one in every twenty people
will develop this cancer sometime in their lives, careful consideration
should be given to your family history.
If a first-degree
relative (mother, father, siblings) has had colon cancer, you may be a
prime candidate. If you have a history of bowel disorders, such
as ulcerative colitis or Crohn’s Disease, your risk is increased as
well. A genetic syndrome known as Familial Cancer Syndrome
also increases your risk of developing this cancer at an early age.
Like many other “silent” cancers, colon cancer can go undetected for a
long time. It begins with pre-cancerous polyps, which are small
protrusions from the intestine’s lining. By age 65, nearly 30
percent of the population has such polyps. If they are left
untreated, up to 12% of those with polyps may develop colon cancer,
says the ACS.
It’s difficult to detect blood in the stool in the early stages of the
disease, but when the tumor becomes large enough to obstruct the bowel,
symptoms will indeed appear and include anemia, rectal bleeding,
fatigue, persistent abdominal pain, and diarrhea or constipation.
Remember that you can also help prevent colon cancer with a few
easy-to-do steps. While regular screening is the most important
tool, individuals are also encouraged to cut down on red meat.
Studies show that just one portion of red meat per week increases your
chances of getting colon cancer by 50%. Sedentary adults are also
more likely to contract the disease. Thirty minutes of exercise each
day will lower your risk as well.
