Colon & Rectal Cancer

Cancer that begins in the colon is called colon cancer, and cancer that begins in the rectum is called rectal cancer. Cancer that starts in either of these organs may also be called colorectal cancer.

In the United States, colorectal cancer is the fourth most common cancer in men, after skin cancer, prostate cancer, and lung cancer. It is also the fourth most common cancer in women, after skin cancer, breast cancer, and lung cancer.

At Arizona Oncology, we understand that a new diagnosis of either colon cancer or rectal cancer can be overwhelming.

We will help you and your family, make individualized treatment decisions in partnership with our medical team.

Review this section’s important information about colorectal cancer diagnosis, staging, and treatment options, as well as colon cancer patient and survivor resources as you prepare for an appointment with your oncologist. After reviewing these sections, ask your cancer care team any additional questions that you may have about your individual situation.

Colon & Rectal Cancer Diagnosis

Colorectal cancer screening is recommended for everyone starting at age 45 using one or more common tests. (Maybe sooner if are you have certain risk factors.) If the results of the cancer screening tests show suspicion of colon or rectal cancer, further tests will likely be required. There are several steps in the diagnosis process including:

  • Physical Exam
  • Blood Tests
  • Colonoscopy
  • Biopsy
  • Imaging Tests


Staging Colorectal Cancers

If you receive a colon or rectal cancer diagnosis you’ll be referred to an oncologist who will plan treatment based on the stage of the cancer, which ranges from Stage 0 to Stage IV. They will evaluate the current test results and may request some additional tests to determine the stage — or how far the cancer has spread. These tests might include:

  • Blood tests
  • Colonoscopy
  • Endorectal ultrasound
  • Chest X-ray
  • CT scan


Colon & Rectal Cancer Treatment Options

Based on the stage, your overall health, and other factors of your colon or rectal cancer, you and your cancer care team will discuss options for your treatment. Those options can include:

  • Surgery
  • Chemotherapy
  • Biologic Therapy
  • Radiation Therapy

The oncologists at Arizona Oncology will help you decide on a plan that’s right for you.
