Colon[ edit ] Gross appearance of an opened colectomy specimen containing two adenomatous polyps the brownish oval tumors above the labels, attached to the normal beige lining by a stalk and one invasive colorectal carcinoma the crater-like, reddish, irregularly-shaped tumor located above the label.

Histopathologic image of colonic carcinoid stained by hematoxylin and eosin. The vast majority of colorectal cancers are adenocarcinomas. This is because the colon has numerous glands within the tissue. Normal colonic glands tend to be simple and tubular in appearance with a mixture of mucus secreting goblet cells and water absorbing cells.

These glands are called glands because they secrete a substance into the lumen of the colon, this substance being mucus. The purpose of these glands is twofold.

The first is to absorb water from the feces back into the blood. The second purpose is to secrete mucus into the colon lumen to lubricate the now dehydrated feces.

This is crucial as a failure to lubricate the feces can result in colonic damage by the feces as it passes towards the rectum. Next, they suggested that k-Ras becomes activated and the polyp becomes a small, benign adenoma.

The adenoma, lacking the "carcinoma" attached to the end of it, suggests that it is a benign version of the malignant adenocarcinoma. The gastroenterologist uses a colonoscopy to find and remove these adenomas and polyps to prevent them from continuing to acquire genetic changes that will lead to an invasive adenocarcinoma.

Bleeding from the tumor is often apparent as the tumor tends to grow blood vessels into it in a haphazard manner via secretion of a number of angiogenesis promoting factors such as VEGF. Histologicallytumours resembling the original structures are classified as well differentiated.

Tumour cells that have lost any resemblance to original tissue, both in appearance and structure form, are denoted as poorly differentiated tumour cells. Regardless of the grade, malignant tumors tend to have a large nucleus with prominent nucleoli.

There will also be a noticeable increase in the incidence of mitosisor cell divisions.
