Adenocarcinoma: The Most Common Type of Colorectal Cancer

adenocarcinoma colorectal cancer

Colorectal cancer begins in the rectum or colon and is the fourth most common cancer found in patients in the United States. Because colorectal cancer is so common, it is important to look out for symptoms. These symptoms include a sudden change in bowel movements such as constipation or diarrhea, blood in stool or from the rectum, bloating, cramps, or constant fatigue. If you are experiencing any of these symptoms, even if they are not severe, it is a good idea to speak with your doctor.

What is the most type of colorectal cancer?

The most common type of colorectal cancer is Adenocarcinoma. Adenocarcinoma is a type of cancer that forms in a mucus-secreting gland that can be diagnosed through biopsy, CT scans or an MRI. The sooner these types of scans can be run, the better, because like all cancer, the earlier stages are easier to get control of. Early stages of colon cancer are very treatable and can be removed or cured.

How Doctors Diagnose Adenocarcinoma

  • When symptoms appear in a patient there are three ways to diagnose this type of cancer: biopsy, a CT Scan, and an MRI.

  • A biopsy removes a small section of the abnormal tissue. After the removal, this section can be observed and examined to determine the issue.

  • A CT Scan is an x-ray that takes a three-dimensional picture of the abnormal tissue so it can be further examined.

  • An MRI uses radio waves to make a picture of the part of the body being scanned.

All of these are just the first step in diagnosing Colorectal Cancer. After the diagnosis, your colorectal specialist can give you options for treatment such as colorectal surgery, chemotherapy, or radiation. It is important to always look out for symptoms and to get annual screenings.
