The Siteman approach to colorectal cancer

Washington University colon and rectal cancer specialists have advanced training in caring for patients with these cancers. Because they have studied these cancers extensively in the lab, our experts are on the leading edge of research in colorectal cancer prevention, diagnosis and care.

What is colorectal cancer?

Colorectal cancer develops when cancerous cells begin to grow and multiply in either your colon or your rectum. Together, the colon and the rectum make up the large intestine. They form the last part of the digestive tract and help move waste out of your body. 

When cells (cancerous or not) grow out of control in your colon or rectum, they form small lumps called polyps. If they’re not removed early (such as during a routine colonoscopy), some polyps can become cancerous. Left untreated, cancer cells can spread from your colon and rectum into other parts of your body. 

The American Cancer Society estimates that around 150,000 people in the U.S. are diagnosed with colorectal cancer each year. And while colorectal cancer is still a leading cause of death, survival rates for the disease are on the rise. Early detection and better treatments are helping more people survive colorectal cancer. 

How is colorectal cancer diagnosed?

There are several different types of screening tests we can use to detect colorectal cancer. These include:

Stool-based tests

These non-invasive options require only a stool sample. Stool-based tests look for signs of blood, while others detect DNA changes that might indicate colorectal cancer.

Virtual colonoscopy

This non-invasive test uses a CT scan to create 3D images of the inside of your colon and rectum.  

Colonoscopy

During a colonoscopy, the doctor inserts a small tube and camera into your colon. You'll be asleep during the procedure. During a colonoscopy, the doctor can not only detect, but also remove polyps.  

Flexible sigmoidoscopy

This procedure is similar to a colonoscopy but looks only at the lower portion of your colon and rectum.
