How Dr. Nghia Nguyen Diagnoses Tubular Adenomas?
Dr. Nguyen uses a step-by-step approach:
Medical History and Exam
He reviews your personal and family history of colon polyps or cancer, asks about symptoms (bleeding, bowel changes) and assesses risk factors.
Colonoscopy
A high-definition scope allows Dr. Nguyen to inspect the entire colon lining. Any polyps found are carefully measured and photographed.
Polypectomy & Pathology
Suspicious growths are removed on the spot. The tissue is sent to our pathology lab to confirm tubular adenoma and check for dysplasia.
Advanced Imaging (if needed)
Narrow-band imaging or chromoendoscopy highlights flat or subtle lesions that might be missed on standard white-light exam.
Endoscopic ultrasound maps deeper or hard-to-see growths, guiding complete and safe removal.

Our Team offers a full range of treatment options for tubular adenomas.
1. Diet and Lifestyle Modifications
Personalized recommendations to increase fruits, vegetables, and whole grains
Guidance on reducing red meat and processed foods
Exercise programs—such as daily walking—for better colon health

2. Medications

Calcium and vitamin D supplements when levels are insufficient
Scheduled follow-up exams to detect and address new growths promptly
3. Minimally Invasive or Advanced Procedures
Colonoscopy with polypectomy for safe, same-session removal of tubular adenomas
Endoscopic mucosal resection for larger or flat polyps that require advanced techniques
Enhanced imaging tools to locate small or hidden growths missed on standard exams

Frequently Asked Questions
What is a tubular adenoma?
It is a noncancerous growth found in the colon or rectum. Removing it lowers your risk of colon cancer.
Are tubular adenomas precancerous?
Yes. While not all become cancer, they can turn into cancer over time if left in place.
How often should I have a colonoscopy after removal?
Follow-up depends on the size and number of polyps. Most people need another exam in three to five years.
Does removal hurt?
No. Removal happens during a sedated colonoscopy. You will not feel pain during the procedure.
Can diet alone prevent polyps?
A healthy diet helps lower risk but does not replace the need for screening.
Do I need to prepare before a colonoscopy?
Yes. You will follow a clear-liquid diet and take a bowel prep as directed by the care team.
Are there non-invasive tests?
Stool tests may find signs of polyps, but they cannot remove them. Colonoscopy is still the best method.
