- Inflammation
Colonic Inflammation Colonic Polyps Multiple polyps seen in colon. [naspghan.org]
Some known causes include: inflammation a foreign object a cyst a tumor mutation in the genes of colon cells chronic stomach inflammation excess estrogen Polyps grow through rapidly dividing cells, which is similar to how cancer cells grow. [healthline.com]
Inflammation: Digestive diseases that cause inflammation, such as inflammatory bowel diseases (Crohn’s disease and ulcerative colitis) can contribute to the formation of polyps. [verywellhealth.com]
Inflammatory polyps may develop among people with ulcerative colitis or Crohn’s disease--inflammatory bowel disease that are characterized by chronic bouts of inflammation of the digestive tract, colon and/or rectum. [livestrong.com]
- Surgical Procedure
The most common surgical treatments are: Total colectomy and ileorectal anastamosis (IRA) Patients with few polyps in the rectum usually undergo this procedure. [my.clevelandclinic.org]
The surgical procedure used depends on where the cancer is located. [healthywomen.org]
You are not looking for a surgeon since EMR is an endoscopic procedure, not a surgical procedure. EMR is basically a normal colonoscopy performed in the gastroenterology department with the use of additional advanced techniques. [sease.com]
After surgical procedures, dense fibrous tissue forms within the abdominal cavity in some patients with FAP. This fibrous tissue tends to aggressively invade the mesentery or retroperitoneal tissues and form tumors. [ncbi.nlm.nih.gov]

Indications for colonoscopy included known or previous colonic polyps or carcinoma, hemoccult positive stool, lower gastrointestinal bleeding, iron deficiency anemia, abnormal barium enema, inflammatory bowel disease, abdominal pain, and family history [ncbi.nlm.nih.gov]
Other less common symptoms include abdominal pain, nausea, vomiting, mucus passage, and anemia [1, 4]. [hindawi.com]

Stool exam. Doctors may also look for the presence of blood in stools or examine the stool DNA. Depending on the results, they may then perform a colonoscopy to investigate further. Doctors will usually treat colon polyps by removing them. [medicalnewstoday.com]
