Colorectal
Cancer
Of
the top ten deadliest forms of cancer in the US, colorectal cancer is ranked as the second highest
type. We will explore further details of the disease including
causes, symptoms, treatments and important statistics.
Colorectal
can be deadly. As a matter of fact between 2003 and 2007 it took 268,783 lives of Americans. According to the
National Cancer Institute (NCI), the death toll for 2012 is estimated to be over 51,000 people so it is
certainly a serious situation. The tragedy with this kind of disease is that it can be highly treatable if
caught in the early phases. However many people either do not have adequate insurance to cover screening tests
or simply don’t find it necessary to do so.
Colon cancer
begins and grows within the tissues of the colon. Rectal cancer
tends to grow in the last few inches of the large intestine. Most
cases of colorectal cancer begin as small clumps of benign cells which are called polyps. If there are left untreated, they can eventually turn
cancerous. Again this is why proper screening is so
essential.
The common
symptoms of colorectal cancer can include the following:
-
Changes
in bowel movements including diarrhea or constipation
-
Rectal
bleeding or blood in the stool
-
Bloating,
cramping and general discomfort in the stomach area
-
Stools
which are thinner than usual
The incidence
of colorectal cancer tends to be higher for the following kinds of individuals: of lung cancer:
-
People
over 50
-
People
with a family history of the disease
-
People
with a history of inflammatory bowel disease
-
People
who are either of African or Ashkenazi Jewish descent
Lifestyle
choices can affect the risk factors so it is important to eat a diet low in red and processed meats, remaining
active, keeping a healthy weight and avoiding nicotine or alcohol.
Colorectal
cancer has different types and stages. Adenocarcinomas generally
account for 95 percent of the cases out there. Mucinous
adenocarcinomas in the next most common type and accounts for about 15 percent of all colon and rectal
adenocarcinomas. Since this type of cancer can be spread through
the mucous, it can intensify and spread to other areas of the body much faster.
The next most
common type following this is signet ring cell adenocarcinomas and only accounts for less that 1% of all cases
in the US. Colorectal is very treatable and offers the patients
good prospects if it is caught in the early stages. This is why it
is so critical to receive proper testing and screening, particularly as the risk factors
increase.
Common types
of diagnostic tests used include the following: of lung cancer:
-
Colonoscopy
– Normally the patient is put to sleep during this procedure and the gastroenterologist examines the
colon for evidence of polyps or other abnormalities. If a polyp is identified, a tissue sample is taken
to check for cancer
-
Endoscopic
Ultrasound – This procedure is less invasive while still providing excellent
If the
disease is present, a number of treatment plans may be implemented.
First of all colorectal surgery may be performed to remove as much cancerous tissue as possible. If the cancer is limited to one or more polyps the prognosis is usually pretty
positive.
Monoclonal
antibody therapy is a relatively new procedure which uses monoclonal antibodies to improve the natural immune
system and help it to attack and destroy cancer cells. This
procedure may be used alone or in conjunction with traditional treatment options.
There are other treatments as well. But it is important to realize
that while colorectal cancer has very sobering statistics, getting regular checkups and screening tests can help to
save lives and lessen the severity of this disease significantly
