Colonoscopy in Los Angeles
Gentle, expert colonoscopy with Dr. Yosef Nasseri — the single most effective way to detect and prevent colon cancer, with comfortable sedation and clear results.
The Gold Standard for Colon Cancer Prevention
A colonoscopy is the most powerful screening tool in modern medicine because it can both detect and prevent colon cancer in a single visit. During the exam, Dr. Nasseri examines the entire lining of the colon and can remove precancerous polyps before they ever have a chance to become cancer.
Most patients are surprised by how easy the experience is. With comfortable sedation, the exam itself is painless and takes about 20 to 30 minutes. You will not remember the procedure, and you will go home the same day.
Whether you are due for routine screening or have symptoms that need answers, our Los Angeles team makes scheduling simple. Explore all colorectal services or learn about colon cancer treatment.
When Should You Have a Colonoscopy?
Screening guidelines have changed, and knowing when to be evaluated can save your life. Dr. Nasseri helps every patient understand the right timing for their situation.
Routine Screening at 45
Guidelines now recommend that average-risk adults begin screening at age 45. If results are normal, the exam is typically repeated every ten years.
Family History or Risk
A family history of colon cancer or polyps, or certain genetic syndromes, means screening should begin earlier and be repeated more often.
Warning Symptoms
Rectal bleeding, changes in bowel habits, unexplained anemia, or abdominal pain should be evaluated promptly, regardless of age.
Preparing for Your Colonoscopy
Good preparation is the key to an accurate exam. In the day before your appointment you will follow a clear-liquid diet and take a prescribed bowel-cleansing solution that empties the colon so Dr. Nasseri can see the lining clearly. Our team walks you through every step and is available to answer questions.
Preparation has become far easier in recent years, with lower-volume, better-tasting options available for many patients. Arrange for someone to drive you home afterward, since the sedation makes it unsafe to drive for the rest of the day.
What Happens During the Exam
A colonoscopy is a smooth, carefully monitored process from start to finish, and most patients are back to normal activity the next day.
Comfortable Sedation
You receive sedation so you are relaxed and feel nothing during the exam. Your breathing and vital signs are monitored the entire time.
Careful Examination
A thin, flexible scope with a high-definition camera allows Dr. Nasseri to inspect the full length of the colon in detail.
Polyp Removal
Any polyps found are removed painlessly during the same visit, preventing them from progressing to cancer.
Biopsies
Small tissue samples may be taken from suspicious areas and sent for analysis to guide any further care.
Same-Day Recovery
After a short recovery period you go home the same day and receive your results and a clear follow-up plan.
What to Expect at Your Visit
From your first phone call to your results, our goal is to make screening simple and stress-free. Dr. Nasseri and his team treat every patient with warmth and respect.

Follow the prep instructions closely, stop certain medications only if directed, and arrange a ride home for the day of your appointment.

You will be comfortably sedated, the exam takes about 20 to 30 minutes, and the whole visit including recovery usually lasts a couple of hours.
