Most rectal cancers begin as a growth called a polyp and develop slowly over many years. Screenings, like colonoscopies, give your physician the opportunity to remove polyps before they become cancerous or to spot cancer at an early stage, when it is easier to cure.
Fred Hutchinson Cancer Center offers comprehensive treatment for rectal cancer from a team of experts who specialize in gastrointestinal cancers.
Cancer can begin in either the colon or the rectum, and it may be called colon cancer or rectal cancer, based on where it started. Sometimes these cancers are referred to together as colorectal cancer.
There are many similarities between colon and rectal cancers, but there are some differences in the ways they are usually treated.
In most cases, colon and rectal cancers develop slowly over many years. Most of these cancers begin as a growth of tissue called a polyp in the inner lining of the colon or rectum. Usually polyps bulge into the colon or rectum; some are flat.
Fred Hutch experts offer comprehensive care for rectal cancer, including advanced treatments and new options available only through clinical studies.
A diagnosis of cancer can feel overwhelming. We have an experienced, compassionate team ready to help. There are many similarities between rectal cancer and colon cancer, but there are some differences in the ways they are usually treated.
Most people don’t have signs or symptoms of colon or rectal cancer early on. That’s why it’s important to have regular colorectal cancer screenings, which can detect cancer at early stages when the cure rate is high.
Cancer that starts in different areas of the colon or in the rectum may cause different signs and symptoms. If you notice any of the following signs or symptoms, let your physician know:
Usually these signs or symptoms are caused by other conditions, like infections, hemorrhoids or inflammatory bowel disease, not cancer. Your doctor can help you figure out just what is causing your symptoms.

Rectal cancers are grouped into stages I through IV, with stage I being the least advanced and stage IV being the most advanced.
The exact cause of colorectal cancer is not known. However, studies show that certain factors are linked to increased risk.
Fred Hutch’s Gastrointestinal Cancer Prevention Program offers a personalized approach to risk assessment, screening and prevention for people at high risk for gastrointestinal cancers.
Using aspirin, nonsteroidal anti-inflammatories or postmenopausal hormones might reduce risk of polyps or colorectal cancer. Talk with your physician to learn more.
