Choose a Colonoscopy

Although nearly 90% of colorectal cancer cases are preventable, colorectal cancer remains the second most common cause of cancer-related death in the United States.

Reluctancy and fears over having a colonoscopy are the main culprits behind this alarming trend. Nischita Merla, MD, gastroenterologist at Pomona Valley Hospital Medical Center (PVHMC), says her patients frequently express anxiety over the procedure and will choose to forgo it.

“In the world of cancer care, you don’t get many opportunities to identify and remove tissue before it becomes cancerous,” says Dr. Merla. “I cannot stress enough how important it is to undergo a colonoscopy, an effective and relatively low risk screening tool.”

Colonoscopy Versus Cologuard

Colonoscopy is the “gold standard” for colorectal cancer screenings and is a recommended screening for individuals at average risk starting at age 45. Not only can this screening detect cancer, but it can also prevent cancer by identifying and removing polyps that can become cancerous in the future.

Cologuard is an option for low-risk patients starting at age 45. It involves the patient taking a self-collection of a stool sample and sending it in the mail for blood and DNA testing.

Cologuard: Every 3 years

False Positive Rate

Cologuard: 13% false positive rate

Test Type

Colonoscopy: Procedure done under sedation in less than an hour

Cologuard: Self-collection stool test

What happens during a colonoscopy?

A period of fasting and drinking a laxative to flush out the colon is required prior to a colonoscopy. The prep liquids used today are easier to drink than prep liquids of the past.

At the hospital, patients will receive an IV sedative to help them relax and feel comfortable. The 15–60-minute procedure uses a flexible tube with a camera at the end to provide a clear look at your gastrointestinal tract.

The doctor will gently pass the tube through the patient's rectum and throughout the colon, taking photos, retrieving samples or immediately removing abnormal growths. During this time, the patient is in a deep sleep and will have no pain and little to no memory of the procedure.

Do I need to have a colorectal cancer screening at 45 if I feel healthy and well?

Yes, even if you feel healthy, don’t delay getting your screening starting at age 45 (or younger if you are considered at high risk). Colorectal cancer often does not cause symptoms in its beginning stages.

Remember, the best screening tool is the one you can commit to doing, whether it's a colonoscopy or the Cologuard. Don’t let fear of discomfort get in the way of your health. Talk to your doctor today about which screening is right for you.
