Conclusions:
Tumor size proved to be an independent prognostic parameter for patients
with colorectal cancer. Optimal cut-off values vary among different parts of the large bowel. Whereas prognostic significance is strong within the colon, it appears to be of minor value within the rectum.

stage IIA cancer
describes a tumor larger than 4 cm but 5 cm or less in size that has not spread to the nearby lymph nodes. Stage IIB lung cancer describes a tumor that is 5 cm or less in size that has spread to the lymph nodes.

cancer describes the size of a tumour and how far it has spread
from where it originated. The grade describes the appearance of the cancerous cells. If you’re diagnosed with cancer, you may have more tests to help determine how far it has progressed.
What is a large tumor in colon?
Colorectal carcinoma
is a cancer, or malignant tumor, of the large intestine, which may affect the colon or rectum. Typically, the colon is the upper five or six feet of the large intestine, and the rectum is the lower five to seven inches located above the anal canal.
Can a bowel tumour burst?
Some tumors grow large enough to block the passage of food through the stomach or intestine. This is called an obstruction, and it can cause severe abdominal pain and vomiting. Because GISTs are often fragile,
they can sometimes rupture
, which can lead to a hole (perforation) in the wall of the GI tract.

Can a large colon tumor be benign?
Giant lipomas
(>4 cm) are the most common benign tumors in the colon that cause intussusception, although no specific incidence data have been documented. Even patients with large lipomas may have nonspecific or intermittent symptoms, which causes delay and difficulty in making the diagnosis.
Is a 2 inch tumor big?
The smallest lesion that can be felt by hand is typically 1.5 to 2 centimeters (about 1/2 to 3/4 inch) in diameter. Sometimes tumors that are 5 centimeters (about 2 inches) — or even larger — can be found in the breast.
Are all Tumours in the bowel cancerous?
Not all tumours are cancer
. Doctors can tell if a tumour is cancer by removing a small sample of tissue or cells from it. This is called a biopsy. The doctors examine the sample under a microscope to look for cancer cells.
What percentage of colon masses are cancerous?
Most information about colorectal cancer refers to colorectal adenocarcinoma, the most common type. Estimates suggest that
4.1 percent of
people may develop colorectal cancer during their life, according to the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) Program.
What is considered a big tumor?
