Question:


Could you give me some facts about colon cancer?
Earl


Answer:

Dear Earl ,

Colorectal cancer, also called colon cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix.

The colon makes up the last six feet of the large intestines and absorbs water.
If you have had colorectal cancer, even though it has been completely removed, you are more likely to develop new cancers in other areas of the colon.

There are at least 160000 cases of colon cancer diagnosed per year in the United States.
and about 62000 die. Colon cancer is more common among women.

Together, colon and rectal cancers account for 10% of cancers.
Colorectal cancer is the third most common cancer in both men and women in the United States.


Prevention and early detection are key factors in controlling and curing colorectal cancer. Indeed, colorectal cancer is the second most preventable cancer.

It's best to get regular screenings rather than rely on colon cancer symptoms to alert you to the presence of a tumor.
This is because colon cancer can grow for years before causing any symptoms.
It takes more than 10 years in most cases for an adenoma to develop into cancer. This is why some colon cancer prevention tests are effective

In making a diagnosis of colon cancer, your doctor will first start by recording your medical history, asking about any symptoms you may be experiencing and conducting a thorough physical examination.

He/she also may recommend one or more of the following diagnostic tests:

-Digital rectal exam involves the doctor or nurse inserting a gloved, lubricated finger into the rectum to feel for any abnormalities.

-Barium enema, also known as a lower gastrointestinal series, takes X-rays of the large intestines.

-Fecal occult blood test is a noninvasive test that detects the presence of hidden, or occult blood in the stool. Such blood may arise from anywhere along the digestive tract. Hidden blood in the stool is often the first, and in many cases the only, warning sign that a person has colorectal disease, including colon cancer.

-Sigmoidoscopy is performed to see inside the rectum and the lower colon and remove polyps or other abnormal tissue for examination under a microscope.

-Colonoscopy is performed to see inside the rectum and the entire colon and remove polyps or other abnormal tissue for examination under a microscope.

-Polypectomy is performed during a sigmoidoscopy or colonoscopy to remove polyps.

-Biopsy is a test in which a small amount of tissue from the suspected area is removed for examination by a pathologist to make a diagnosis.

The choice of treatment for colorectal cancer depends largely on the stage the patient is in. Possible treatments include surgery, chemotherapy, radiation.

Mayo Clinic is a world leader in colon cancer diagnosis and treatment, performing more than 2500 surgical procedures per year

n addition to age, other high risk factors include a family history of colorectal cancer and polyps and a personal history of ulcerative colitis, colon.

Colon cancer is one of the most preventable kinds of cancer. Half of all cases could be prevented through lifestyle changes and regular screening.

It is one of the most preventable forms of cancer. It almost always starts with non-cancerous growths (called polyps) that develop on the lining

When colon cancer is caught early, it is easily treated and often cured. Still, it is the second leading cause of cancer deaths in America
