A colonoscopy is a medical procedure that allows a doctor to examine the lining of your large intestine (colon and rectum).
A thin, flexible tube with a camera on the end (colonoscope) is inserted into your anus and moved through your colon. The camera sends images of your colon to a monitor, allowing the doctor to look for any abnormalities.
Colonoscopies are often used to screen for colorectal cancer, which is the third leading cause of cancer-related deaths in the United States.

- Thin, flexible tube with camera.
- Inserted into anus, moved through colon.
- Images sent to monitor for examination.
- Used for colorectal cancer screening.
- Third leading cause of cancer deaths.
- Recommended for adults over 50.

Thin, flexible tube with camera.
The colonoscope is a thin, flexible tube with a camera on the end. It is about the thickness of a finger and about 4 feet long.
- Camera:
The camera at the tip of the colonoscope sends images of the colon to a monitor.
- Light source:
The colonoscope also has a light source to help the doctor see the inside of the colon.
- Air and water channels:
The colonoscope has channels that allow air and water to be pumped into the colon. This helps to inflate the colon and make it easier to see.
- Controllable tip:
The tip of the colonoscope can be controlled by the doctor to move it around the colon.
The colonoscope is a very versatile tool that allows the doctor to get a clear view of the inside of the colon. This makes it possible to diagnose and treat a variety of conditions, including colorectal cancer, polyps, and inflammatory bowel disease.
Inserted into anus, moved through colon.
Once the colonoscope is inserted into the anus, it is gently moved through the rectum and into the colon. The doctor will use the controllable tip of the colonoscope to guide it around the colon, examining the lining of the colon as it goes.
- Preparation:
Before the colonoscopy, you will need to clean out your colon so that the doctor can get a clear view. This is done by drinking a special laxative solution and following a restricted diet.
- Procedure:
The colonoscopy procedure itself usually takes about 30 minutes. You will be given a sedative to help you relax and make the procedure more comfortable. The doctor will insert the colonoscope into your anus and advance it through your colon.
- Withdrawal:
Once the colonoscope has reached the end of your colon, the doctor will slowly withdraw it while continuing to examine the lining of your colon.
- Removal:
When the colonoscope is completely removed, the procedure is complete.
Colonoscopies are generally safe and well-tolerated procedures. However, some people may experience mild discomfort, such as abdominal cramping or bloating. You may also feel tired after the procedure.
Images sent to monitor for examination.
The camera on the end of the colonoscope sends images of the colon to a monitor. The doctor will watch the monitor carefully as the colonoscope is moved through the colon, looking for any abnormalities.
- Real-time viewing:
The doctor can see the images of the colon in real time on the monitor. This allows the doctor to identify any areas of concern that need to be examined more closely.
- Magnification:
The colonoscope has a magnification feature that allows the doctor to zoom in on areas of the colon that need to be examined more closely.
- Still images and videos:
The doctor can take still images or videos of any areas of concern. These images and videos can be used for further evaluation or to track the progress of a condition over time.
- Documentation:
The images and videos taken during the colonoscopy can be stored in the patient's medical record for future reference.
The images sent to the monitor during a colonoscopy allow the doctor to get a clear view of the inside of the colon and to identify any abnormalities that may be present.
Used for colorectal cancer screening.
Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Colonoscopies are used to screen for colorectal cancer by identifying precancerous polyps and cancerous growths in the colon and rectum.
- Early detection:
Colonoscopies allow doctors to detect colorectal cancer at an early stage, when it is more likely to be curable.
- Removal of polyps:
During a colonoscopy, the doctor can remove any precancerous polyps that are found. This can help to prevent colorectal cancer from developing.
- Surveillance:
People who have a history of colorectal cancer or who are at high risk of developing colorectal cancer may need to have regular colonoscopies to monitor their colons for any changes.
- Peace of mind:
A negative colonoscopy result can give you peace of mind knowing that you are free of colorectal cancer.
Colonoscopies are an important tool for preventing and detecting colorectal cancer. If you are over the age of 50, talk to your doctor about getting a colonoscopy.
Third leading cause of cancer deaths.
Colorectal cancer is the third leading cause of cancer-related deaths in the United States, after lung cancer and breast cancer. In 2023, it is estimated that there will be over 150,000 new cases of colorectal cancer diagnosed in the United States and over 50,000 deaths from the disease.
Colorectal cancer is a cancer that starts in the colon or rectum. The colon is a long, coiled organ that is responsible for absorbing water and nutrients from food. The rectum is a short, straight organ that connects the colon to the anus. Colorectal cancer can occur in either the colon or the rectum, and it is often referred to as colon cancer or rectal cancer, depending on where it starts.
Colorectal cancer is a serious disease, but it is often curable if it is detected early. Colonoscopies are an important tool for detecting colorectal cancer early, when it is most treatable. During a colonoscopy, the doctor can examine the entire colon and rectum for any signs of cancer or precancerous polyps.
If you are over the age of 50, you should talk to your doctor about getting a colonoscopy. Colonoscopies are recommended for all adults over the age of 50, and they should be repeated every 10 years or more frequently if you have a family history of colorectal cancer or other risk factors.
Colorectal cancer is a preventable and treatable disease. By getting regular colonoscopies, you can help to reduce your risk of developing colorectal cancer and improve your chances of a cure if you do develop the disease.
