Had a colonoscopy this week, and my doctor said that a 12mm colon polyp is considered medium size.
11.81 inches
3 mm is considered diminutive, ie small. Something that is 1 cm (ie 10 mm) or more is large.
Yes, a polyp measuring 8 cm is considered large. Most polyps are typically much smaller, often measuring just a few millimeters to a couple of centimeters. Larger polyps can have a higher risk of being cancerous, so they usually warrant further evaluation and monitoring by a healthcare professional.
A 21 mm polyp is approximately 2.1 cm in size. Polyps are abnormal growths that can occur in various parts of the body, including the colon, stomach, or uterus, and they can sometimes be precancerous. The size of the polyp plays a role in determining the appropriate treatment and monitoring plan.
A 30 cm polyp in the colon is exceptionally large and would appear as a significant growth protruding from the colonic wall. It may have a lobulated or irregular surface, and its color can vary from pink to reddish, sometimes with areas of ulceration or necrosis. Depending on its type, it could be sessile (flat) or pedunculated (attached by a stalk). Such a size would likely raise concerns for malignancy, and it would be a focal point of investigation during a colonoscopy.
The average colon is about 1.5 m long. Lengths of the various parts are: * Anal canal: 5 cm * Rectum: 12 cm * Sigmoid colon: 40 cm * Descending colon: 15 cm * Transverse colon: 45 cm * Ascending colon: 25 cm The splenic flexure is thus at around 72 cm from the anal verge, and the hepatic flexure at around 117 cm.
Sigmoid colon
Subdivisions of large intestineCaecum (5-8 cm lying between the small intestine and ascending portion of colon)Appendix (blind ending finger like projection at the end of caecum)Ascending portion of colon (which goes up the right side of body to the level of liver)Transverse portion of colon (lying horizontally below the liver and stomach)Descending portion of colon (passes down to the left side of body)Sigmoid part of colon (slightly bent and enters the rectum)Rectum (21-23 cm long opens into anal canal)Anal canal (2.5 cm long)
The Sigmoid Colon It forms a loop that averages about 40 cm. in length,
I'm assuming that you mean large intestine. If so, then it has an average length of about 1.5 meters (5 ft) and a width of 7.5 cm (3 in.). The colon is the largest portion, and the average colon weighs approximately four pounds.
the colon maximum lenght is 1194 cm Joymaker RN
