What is a serrated colon polyp?

Serrated polyps are a type of growth that stick out from the surface of the colon or rectum. The polyps are defined by their saw-toothed appearance under the microscope. They can often be hard to find. The only way to determine the types of polyps is by removing them and examining them under a microscope.

What percentage of sessile serrated polyps become cancerous?

Removing polyps will reduce the risk of the polyp becoming cancerous in the future. This is an especially good idea for serrated sessile polyps. According to one study, 20 to 30 percent of colorectal cancers come from serrated polyps.

How common are serrated polyps?

Serrated polyps are common and are detected in 20% of all colonoscopies in average-risk subjects [6]. However, SPS as an entity is distinguished from the SP by the number, size, and location of these polyps.

Is a serrated polyp bad?

Of these categories, the sessile serrated polyp is the most challenging to identify, hardest to remove, and most likely to develop into cancer. Sessile serrated polyps are common and tend to carry a low risk of becoming cancerous as long as they do not contain major cellular changes.

How often should you have a colonoscopy if precancerous polyps are found?

If your doctor finds one or two polyps less than 0.4 inch (1 centimeter) in diameter, he or she may recommend a repeat colonoscopy in five to 10 years, depending on your other risk factors for colon cancer. Your doctor will recommend another colonoscopy sooner if you have: More than two polyps.

How long does it take for a sessile serrated polyp to turn cancerous?

Some evidence suggests that the sessile serrated polyp-to-cancer sequence takes 10 to 20 years, the same time frame generally accepted for the conventional adenoma-to-cancer sequence. However, approximately half of the cancers in the serrated pathway have microsatellite instability.

Are sessile serrated polyps cancerous?

What does it mean if I have an adenoma (adenomatous polyp), such as a sessile serrated adenoma or traditional serrated adenoma? These types of polyps are not cancer, but they are pre-cancerous (meaning that they can turn into cancers).

Do precancerous polyps grow back?

Once a colorectal polyp is completely removed, it rarely comes back. However, at least 30% of patients will develop new polyps after removal. For this reason, your physician will advise follow-up testing to look for new polyps. This is usually done 3 to 5 years after polyp removal.

What not to eat if you have colon polyps?

Foods to limit Research suggests that eating less of the following foods may have health benefits and may lower your chances of developing polyps: fatty foods, such as fried foods. red meat, such as beef and pork. processed meat, such as bacon, sausage, hot dogs, and lunch meats.

What percentage of polyps are cancerous?

Polyps are common in American adults, and while many colon polyps are harmless, over time, some polyps could develop into colon cancer. While the majority of colon cancers start as polyps, only 5-10% of all polyps will become cancerous.

What does it mean if I have a sessile serrated polyp?

What does it mean if I have an adenoma (adenomatous polyp), such as a sessile serrated adenoma or traditional serrated adenoma? These types of polyps are not cancer, but they are pre-cancerous (meaning that they can turn into cancers). Someone who has had one of these types of polyps has an increased risk of later developing cancer of the colon.

How many serrated polyps have been reclassified as SSPs?

In 2010, Kim et al re-evaluated the pathology of 49 serrated polyps larger than 1 cm that had previously been reported as HPs and re-classified almost 20% as SSPs [7]. More recently, Tinmouth et al found that almost 30% of HPs larger than 5 mm removed between 2003 and 2008 were reclassified to SSPs upon review using current WHO criteria [8].

What is the detection rate of proximal serrated polyps?

The proximal serrated polyp detection rate differed significantly among endoscopists ranging from 6% to 22% [ 28 ]. The histologic classification of SSPs also varies significantly among pathology laboratories.

How is a person diagnosed with serrated polyposis?

SPS is a condition that is defined by WHO. The diagnosis is based on what the doctor sees during a colonoscopy (an endoscopic evaluation of the colon and rectum). The diagnosis is confirmed by a pathologist who looks at the polyps under a microscope. A patient meeting any one of the following criteria is diagnosed with SPS:
