PPCS is caused by an electrocautery-induced injury to the wall of the colon that occurs during removal of colon polyps. [3] PPCS occurs when the electric current extends beyond the mucosa, entering the muscularis propria and serosa, resulting in a full thickness (transmural) burn injury. [ 1 ]
The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
Affected individuals have an increased risk of colorectal cancer, precancerous colon polyps and an increased risk of several additional cancers. About 1–2 percent of the population possess a mutated copy of the MUTYH gene, and less than 1 percent of people have the MUTYH-associated polyposis syndrome.
This provocative study demonstrates that biological age, which can be evaluated by a blood test, is associated with a higher incidence of precancerous colon polyps.” — Anton Bilchik, MD, PhD ...
For instance, if you have a chronic bowel condition, a family history of colon polyps or a family history of colon cancer, you may need your first screening colonoscopy earlier than 45 years old ...
The colorectal adenoma is a benign glandular tumor of the colon and the rectum. It is a precursor lesion of the colorectal adenocarcinoma ( colon cancer ). [ 1 ] [ 2 ] [ 3 ] They often manifest as colorectal polyps .
Volcanic ash accumulates on buildings, and its weight can cause roofs to collapse. A dry layer of ash 4 inches thick weighs 120 to 200 pounds per square yard, and wet ash can weigh twice as much. ...
Even before the results of the National Polyp Study linked colon polyps to colon cancer, Shinya instinctively "thought the polyp was the forerunner of cancer and that removing these polyps could reduce the risk of cancer" (Sivak 2004, p. 979). Since polyp removal accounted for 30% of the colon surgery of the day, Shinya's primary focus from his ...
