Hayward Doctor Excels in Quality Measurement

Hayward Doctor Excels in Quality Measurement

Prevention is better than cure.


David Lynn, MD

David Lynn, MD has performed over 1,700 colonoscopies over the last 13 years.

Colonoscopy: A colorectal cancer screening method.

The gold standard for colon and rectal cancer screening is a quality colonoscopy. This is an outpatient procedure performed by a physician. If precancerous polyps are found, the overwhelming majority can be removed while they are small before they ever become a problem. 

There are other screening tests available that are less invasive (such as Cologuard® or other blood tests). However, these are not as sensitive as a colonoscopy, and need to be done more frequently. Individuals who have a history of polyps, inflammatory bowel disease, gastrointestinal bleeding (such as hemorrhoids), or a family history of colon cancer should NOT have these tests. These individuals should have a colonoscopy instead. 

Average risk individuals should begin screening at age 45, and should continue at least every 10 years. Individuals with a family history of colon cancer or colon polyps may need screening at an earlier age. The same applies for patients with a diagnosis of inflammatory bowel disease (Crohn’s disease or ulcerative colitis).


A difference in quality.

A Colonoscopy is a common cancer-screening procedure, but there can be a measurable difference in quality. Adenoma detection rate (ADR) is a reportable measurement of the surgeon’s ability to find precancerous polyps and remove them. As shown in this graphic, physicians find and remove precancerous polyps in an average of 39.08% of patients (above the benchmark of 25%). Dr. David Lynn detects and removes precancerous polyps in 66.26% of patients.


Saving local lives.

The detection and removal of polyps in 66.26% of patients is a sobering statistic, and shows the importance of colonoscopies. According to the American Cancer Society®, colorectal cancer is the third most common cancer diagnosed in the United States with over 106,000 new cases each year. Dr. David Lynn is detecting almost twice as many precancerous polyps than the national average.
