When Should You Get a Colonoscopy?

In 2019, about 145,600 men and women in the U.S. received a colorectal cancer diagnosis. Although the condition mainly affects older adults, there's a rising incidence in younger individuals. When detected early, it's often curable. Prevention is possible using an imaging test that looks for abnormalities in the lining of the large intestine. At his Newport Beach, CA, office, Dr. Glenn D. Madokoro recommends a colonoscopy to healthy patients with an average, increased, or high risk of developing colon cancer or dangerous polyps. If you're under 45 and have a family history, schedule a consultation with our gastroenterologist to learn when you should undergo this procedure.

What is a Colonoscopy?

During this screening test, Dr. Glenn D. Madokoro uses an instrument called a colonoscope. It's the size of a thin, flexible tube with a lens and light source that allows him to view images on a video monitor. For the outpatient procedure conducted in our Newport Beach, CA, office, there are different sedation options that we'll address amidst your initial consultation. During, the doctor gently inserts this small camera into the anus, gradually pushing it further into the rectum and colon to search for abnormal tissue. If something is a cause for concern, he may take a biopsy sample or remove polyps that might be pre-cancerous or cancerous.

When Should You Get a Colonoscopy?

Nowadays, you're never too young for a colonoscopy, and increased awareness, as well as screening, could save up to 30,000 lives each year. Although early stages of colorectal cancer don't typically have any symptoms, a doctor may recommend this procedure when the following are present:

  • Abdominal discomfort or bloating
  • Dark patches of blood in the stool
  • Unexplained fatigue or weight loss
  • Bleeding or cramping in the rectum
  • Inability to pass a bowel movement

Colorectal cancer is the third leading cause of cancer-related fatalities in the United States. Dr. Glenn D. Madokoro is trained and experienced to identify symptoms early and create an effective treatment plan aimed at saving lives.
