What is Bowel Cancer?
Bowel cancer, also known as colorectal cancer, develops from the inner lining of the bowel and is usually preceded by growths called polyps. Depending on where the cancer begins, it may be called colon or rectal cancer. About 90% of bowel cancers are adenocarcinomas, which start in the glandular tissues lining the bowel. Other less common types of cancer can also affect the bowel. People aged 50-74 are sent a bowel screening test every two years as part of the National Bowel Cancer screen program.
| Type of Cancer | Definition |
|---|---|
| Adenocarcinoma | The most common type of bowel cancer that starts in the glandular tissues lining the bowel. |
| Squamous Cell Carcinoma | A type of cancer that develops in the cells lining the anal canal or rectum. |
| Neuroendocrine Tumours | A less common type of bowel cancer that starts in the hormone-producing cells of the bowel. |
| Sarcomas | A rare type of bowel cancer that develops in the connective tissues of the bowel. |
The National Bowel Cancer Screening Program aims to detect bowel cancer at an early stage when treatment is more effective. By identifying and removing polyps during screening, the risk of developing bowel cancer can be significantly reduced.

Diagnosis of Bowel Cancer
Diagnosing bowel cancer involves several tests that help detect the presence of cancer and determine its extent. These tests are performed by healthcare professionals who specialize in diagnosing and treating gastrointestinal conditions. The following are some common diagnostic tests for bowel cancer:
Physical Examination
A physical examination may be performed to evaluate your overall health and look for any signs of bowel cancer. The doctor may feel your abdomen for any abnormalities, such as lumps or masses, and check for other potential symptoms.
Blood Tests
Blood tests can provide valuable information about your health, including the presence of certain markers that may indicate bowel cancer. These markers, such as carcinoembryonic antigen (CEA), are substances that are often elevated in individuals with bowel cancer.
Immunochemical Faecal Occult Blood Test (iFOBT)
The immunochemical faecal occult blood test (iFOBT) is a simple and non-invasive test that detects tiny traces of blood in the stool. The presence of blood in the stool may indicate the presence of bowel cancer or other gastrointestinal conditions.
Colonoscopy
A colonoscopy is a procedure that allows a doctor to examine the inside of the colon and rectum using a long, flexible tube with a camera on the end. This test can help identify any abnormalities, such as polyps or tumors, and also allows for the collection of tissue samples (biopsies) for further analysis.
Flexible Sigmoidoscopy
Similar to a colonoscopy, a flexible sigmoidoscopy is a procedure that examines the lower part of the colon and rectum using a flexible tube with a camera. However, this test examines a smaller portion of the colon compared to a colonoscopy.
MRI Scan
An MRI (magnetic resonance imaging) scan uses powerful magnets and radio waves to create detailed images of the inside of the body. This imaging test can help identify the extent of the cancer and determine if it has spread to other areas.
CT Scan
A CT (computed tomography) scan uses X-rays and a computer to produce cross-sectional images of the body. This test can help evaluate the size and location of the tumor, as well as check for the presence of cancer in the lymph nodes or other organs.
PET Scan
A PET (positron emission tomography) scan involves injecting a small amount of radioactive material into the body and then taking images using a specialized camera. It can help determine if the cancer has spread to other parts of the body, such as the liver or lungs.
These diagnostic tests play a crucial role in accurately diagnosing bowel cancer and determining the most appropriate treatment plan. It is important to discuss any concerns or questions you may have about these tests with your healthcare provider.
Treatment for Bowel Cancer
When it comes to treating bowel cancer, there are various options available depending on the stage of the cancer and the individual’s overall health. The main treatment for early bowel cancer is surgery, which involves removing the cancerous tissue from the bowel.
For advanced bowel cancer, systemic treatment may be used. This includes radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Radiation therapy uses high-energy beams to destroy cancer cells, while chemotherapy involves the use of drugs to kill or slow down the growth of cancer cells. Targeted therapy focuses on specific molecules in cancer cells, while immunotherapy boosts the body’s immune system to fight against cancer.
In some cases, palliative care may be recommended for individuals with advanced bowel cancer. Palliative care aims to improve the quality of life by managing symptoms and providing emotional support.
It is important to consult with your healthcare team to determine the most appropriate treatment plan for you. They will consider factors such as the stage of the cancer, your overall health, and your personal preferences to develop a tailored treatment approach.
Comparison of Treatment Options for Bowel Cancer
| Treatment Option | Description |
|---|---|
| Surgery | Main treatment for early bowel cancer, involves removal of cancerous tissue from the bowel. |
| Radiation Therapy | Uses high-energy beams to destroy cancer cells. |
| Chemotherapy | Uses drugs to kill or slow down the growth of cancer cells. |
| Targeted Therapy | Focuses on specific molecules in cancer cells. |

| Palliative Care | Focuses on improving the quality of life for individuals with advanced bowel cancer. |
Screening and Prevention of Bowel Cancer
Regular screening plays a crucial role in the early detection of bowel cancer. By undergoing timely screenings, you increase the chances of identifying the disease at an early stage when treatment is often more effective. There are two main screening tests used for detecting bowel cancer: the faecal occult blood test (FOBT) and colonoscopy.
The faecal occult blood test (FOBT) involves analyzing small samples of your stool to check for hidden blood. This test is non-invasive, convenient, and can be done at home. It is recommended that individuals with an average risk of bowel cancer, starting around the age of 45, consider undertaking the FOBT as part of their regular healthcare routine.
Colonoscopy is a more thorough screening procedure that involves examining the inside of your colon and rectum using a flexible tube with a camera. This test allows for the detection of any abnormalities, such as polyps or tumors, which can then be further investigated or removed. Colonoscopy is typically recommended for individuals with an increased risk of bowel cancer or those who have received abnormal results from the FOBT.
In addition to screening, taking preventive measures can significantly reduce the risk of developing bowel cancer. Making lifestyle modifications that promote overall health and well-being is paramount. Here are some key preventive measures:
- Maintain a healthy weight: Obesity has been linked to an increased risk of bowel cancer. Regular exercise and a balanced diet can help you achieve and maintain a healthy weight.
- Stay physically active: Engaging in regular physical activity, such as brisk walking, cycling, or swimming, can lower the risk of bowel cancer.
- Eat a healthy diet: Include plenty of fruits, vegetables, whole grains, and fiber in your diet. Limit the consumption of processed foods, red meat, and foods high in saturated fats.
| Preventive Measures | Effectiveness in Bowel Cancer Prevention |
|---|---|
| Maintaining a healthy weight | Reduces the risk of developing bowel cancer |
| Regular exercise | Reduces the risk of developing bowel cancer |
| Consuming a balanced diet | Reduces the risk of developing bowel cancer |
