Colorectal cancer screening and endoscopic polypectomy can reduce colorectal cancer mortality and are now recommended by many national guidelines. Sling polypectomy and endoscopic mucosal resection (EMR) are the established standards of treatment for polyp removal.

Endoscopic polypectomy and endoscopic mucosal resection (EMR) are the established standards of treatment for colorectal polyps. Cold snare resection is the emerging standard for the treatment of smaller polyps (<5 mm) and may also be appropriate for the removal of noncancerous polyps up to 9 mm. This approach avoids thermal injury, reduces procedure time, and may reduce the risk of late bleeding.

According to the World Health Organization (WHO) 2018, stomach cancer is the most common cancer, after liver cancer and lung cancer in frequency, accounting for 10% of all cancers.

Endoscopic submucosal resection may be indicated for people with early-stage esophageal cancer or precancerous lesions. This technique has the advantages of being minimally invasive, highly effective in curing cancer, and with a quick recovery time.
