Bowel Cancer

Bowel cancer, also known as colorectal cancer, is a type of cancer that begins in the colon or rectum.

It is one of the most common types of cancer worldwide and can affect both men and women.
Bowel cancer incidence varies globally, with higher rates observed in developed countries. Several factors contribute to its development, including age, family history of colorectal cancer or polyps, inflammatory bowel disease (such as Crohn’s disease or ulcerative colitis), and lifestyle factors.

However, bowel cancer in younger people has been rising since the 1980s. Now, one in 10 new bowel cancer cases occur in people under the age of 50.

Prevention

Several lifestyle modifications reduce the risk of bowel cancer. Adopting a healthy diet rich in fruits, vegetables, and whole grains while limiting the consumption of red and processed meats can lower the risk. Regular physical activity, maintaining a healthy weight, avoiding smoking, and moderating alcohol intake also play significant roles in prevention. New research is being done on the role of the gut microbiome in this space.

Early detection

Early detection through screening can lead to better outcomes by identifying precancerous polyps or early-stage cancers, when treatment is more effective.

For people at low – average risk and no symptoms:

  • The National Bowel Cancer Screening Program (NBCSP) offers free screening kits to Australians aged 45 to 74 every two years.
  • From 1 July 2024, the eligibility age for this program will be reduced to 45. If you are an Australian aged between 45 to 49, you will need to request your first bowel cancer screening kit by submitting a webform or calling 1800 627 701.
  • The program uses a non-invasive test called a faecal occult blood test (FOBT), which detects tiny/microscopic amounts of blood in stool samples, potentially indicating the presence of polyps or bowel cancer.
  • The screening process is straightforward: Individuals receive a kit by mail, collect a small stool sample at home, and send it to a laboratory for analysis using a prepaid envelope. If the test detects blood, further diagnostic procedures, such as a colonoscopy, are recommended.
  • Early detection through the NBCSP significantly increases the chances of successful treatment and survival, as bowel cancer is highly treatable when found early. Despite the program’s effectiveness, participation rates are below optimal levels, with many eligible individuals not completing the test.
 More information about screening

For people at increased risk:

This could be due to family history or certain medical conditions – a different screening pathway is used. These people may be offered colonoscopy directly.

For people with signs or symptoms:

The screening pathways don’t apply. The focus is on a diagnosis of the symptom. Symptoms such as changes in bowel habits, rectal bleeding, abdominal pain, unexplained weight loss, persistent fatigue and iron deficiency anaemia should always prompt further evaluation. Many times, a colonoscopy is part of this workup. Please see your GP to discuss this.

Treatment

Treatment for bowel cancer depends on several factors, including the stage of cancer, its location, overall health, and individual preferences. Common treatment modalities include surgery, chemotherapy, radiation therapy, and sometimes immunotherapy.

Dr Rajan attends a multidisciplinary team meeting, where complex cases can be discussed, and consensus on best treatment options can be made in conjunction with other specialists.

The primary treatment for early-stage bowel cancer involves surgical removal of the tumour and surrounding tissues. In some cases, minimally invasive techniques such as laparoscopic or robotic-assisted surgery may be used to reduce recovery time and complications.

Chemotherapy may be recommended before or after surgery to shrink tumours, prevent cancer recurrence, or manage advanced-stage cancer.

Radiation therapy may be used in combination with surgery or chemotherapy to target and destroy cancer cells, particularly in locally advanced or rectal cancers.

These newer treatment approaches target specific molecular or immune system pathways involved in cancer growth and progression. They are often used in combination with other treatments for advanced-stage or metastatic bowel cancer.
