What Is Colon Cancer? - A Infection That Have Nerve to Destroy!
According
to the World Health Organization (WHO), cancer is one of the leading causes of
death across the globe, particularly in Western countries such as the United
States. In fact, in year 2008, 13 percent (13%) or 7.6 million of colon and rectal cancer infected people the total deaths of people
worldwide is due to cancer. Among more than hundred types of malignancies,
Colorectal Cancer lands at the fourth spot of the most common cancers among men
and women.
Colon rectal Cancer is the abnormal growth of cells or tumor formation in the large
intestine (large bowel or colon) and the rectum. These cells can spread
(metastasize) and damage other tissues or organs in the body; thus, referred to
as cancer cells. Basically, the colon serves as storage site for the feces
before being excreted from the body, while the rectum is the distal end of the
colon that is adjacent to the anus. These structures of the digestive tract are
the main sites for Colon rectal Cancer, but cancer cells can also metastasize to
the liver, lungs and other vital organs. Consequently, injury to the different
body organs caused by cancer cells leads to several organ dysfunctions that can
result to a person's death.
The
most common causes of cancer are as follows
•
Genetic or hereditary origin;
•
High dietary fat intake;
•
Low-fiber diet (low vegetable and fruit consumption)
•
Polyps (non-cancerous tumor) that are not removed from the colon; and
•
Ulcerative colitis
Studies
revealed that people with family history of colon cancer are high risk of
developing the disease. Another cause of colon cancer is high fat dietary
intake. Various researches show that the metabolism (breakdown) of fats results
to the production of free radicals or carcinogens, which are substances that
cause cancer. Meanwhile, low fiber dietary intake is generally associated with
poor bowel movement resulting to diminished ability of the body to eliminate
waste products including carcinogens. Cancer in the colon and rectum is also
believed to be a complication of Chronic Ulcerative Colitis (bowel inflammatory
disease) and polyps that have not been removed.
An
individual with colon and rectal cancer will experience signs and symptoms that
are also commonly observed to other bowel disorders and some of which are
non-specific. These manifestations include:
•
Diarrhea (constipation and stool reduced if the tumor obstructs passageway for
feces);
•
Abdominal pain, bloating or cramps;
•
Sudden weight loss
•
Fresh or old red blood, dark blood in stools leading to anemia
•
Body weakness or fatigue; and
•
Shortness of breath
Hence,
specific diagnostic exams are conducted to determine presence of colon cancer
such as GI series and Colonoscopy. The confirmatory test for cancer is biopsy.
This procedure is done by taking sample tissues from the colon during
colonoscopy and studying them through a microscope. Then, another series of
diagnostic exams including chest x-ray, ultrasonography of the whole abdomen or
CAT scan of the lungs and abdomen are performed to verify spread of colon
cancer cells to other organs in the body. Carcinoembryonic antigen (CEA), a
cancer marker can also be used to determine cancer metastasis through blood
test.
Moreover,
the most definitive treatment for colon rectal cancer is surgery, in which the
affected bowel is cut and removed and the unaffected parts are connected.
Chemotherapy and radiotherapy may also be part of the treatment plan depending
on the stage of cancer.
In
general, there are treatments for colon rectal cancer, but they are merely
intended to relieve the signs and palliative symptoms. Regrettably, cancer
remains incurable. A person can live for months or years after the diagnosis of
cancer, but is always at risk of premature death, even in the presence of a
palliative treatment. Like all other types of cancer, having colon cancer is a
sobering diagnosis. However, awareness of the disease is what makes people more
alert about health issues.
