Dr. Robert Webman is a gastroenterologist and associate professor at UCLA who performs endoscopic procedures like colonoscopies. Colonoscopies are used to detect abnormalities in the lower digestive tract and screen for colorectal cancer. The American Cancer Society recommends that people with average risk get their first colonoscopy at age 45 and follow-up exams every 10 years, while those with higher risk factors like family history or digestive conditions start screenings earlier and get them more frequently, with follow-ups within 5 years if tumors or polyps are detected.

2. Introduction
Gastroenterologist and UCLA associate professor Robert M. Webman, MD, is affiliated with the
American Gastroenterological Association and the California Medical Association. Dr. Robert
Webman performs restorative and preventive endoscopic procedures, such as sphincterotomies,
esophagogastroduodenoscopies, and colonoscopies.
Colonoscopies are used by gastroenterologists to detect abnormalities in the lower digestive
tract. While these tests can be ordered to investigate symptoms such as rectal bleeding or
abdominal pain, they are also used as a screening tool for colorectal cancers. The American
Cancer Society issues guidelines for the frequency and age recommendations for colonoscopy
screenings.

3. People who have an average risk of colorectal cancer should schedule their first screening
at 45 and get follow-up exams every 10 years. Individuals with higher risk factors, such as a
family history of colorectal cancers and tumors or pre-existing digestive conditions such as
Crohn’s disease, should start screenings earlier and schedule them more frequently. If
tumors or polyps are detected during a screening, the patient should also have a follow-up
exam within five years.
