​​​Ab​​out the Program

The Colon Screening Program started in BC in November 2013. Colon cancer screening in BC is organized under a partnership framework with regional health authorities, laboratory service providers, primary care providers, and specialists. BC Cancer provides oversight for organized cancer screening in BC and supports:

  • development of provincial policies, guidelines, and standards
  • development of strategies to increase public and health care provider awareness, including both benefits and limitations of screening
  • correspondence to eligible British Columbians about results, follow-up, and rescreening
  • quality assurance and quality improvement of the program
  • reporting and monitoring of system performance and screening outcomes. 

Eligibility

Should my patient get colon screening? Generally, anyone between the ages of 50 to 74 with no symptoms should get screened with a Fecal Immunochemical Test (FIT) every 2 years.

​Asymptomatic - Av​​​erage Risk 

Age 49 and under

No history
  • Routine FIT screening is not recommended
Personal history of low-risk precancerous lesion(s)

Age 50 to 74

Personal history of low-risk precancerous lesion(s)
  • FIT or colonoscopy is recommended. Refer to the Colonoscopy Follow-up Algorithm for the recommended pathway and screening interval.
  • If patient is younger than age 74, depending on the recommendation, either refer for colonoscopy using the Colonoscopy Referral Form or refer for FIT using the Standard Lab Requisition.
Never screened or screening interval elapsed and n​o personal or family history of colorectal cancer
  • Routine FIT screening every 2 years.
  • Use Standard Lab Requisition: Select ‘FIT (Age 50-74 asymptomatic q2y) Copy to Colon Screening Program.
Normal FIT within 2 years
  • Routine FIT screening is not recommended. Patient is up to date with colon screening.
Normal colonoscopy within 10 years
  • Routine FIT screening is not recommended. Patient is up to date with colon screening.
Normal CT colonography within 5 years
  • Routine FIT screening is not recommended. Patient is up to date with colon screening.

Age 75 to 84

Assess patient’s risk of colorectal cancer and risk of colonoscopy. Harm can outweigh benefit; use clinical judgement.

If proceeding with screening, use Standard Lab Requisition and select ‘FIT No copy to Colon Screening Program’. Patient will not be registered in the program. Refer directly to a specialist for follow-up when indicated.

Age 85 and over

Routine FIT screening is not recommended.

​​​​​​​​​​​High R​​​isk

Personal history of high-risk precancerous lesion(s)

FIT or colonoscopy is recommended. Refer to the Colonoscopy Follow-up Algorithm for the recommended pathway and screening interval.

If patient is younger than age 74, depending on the recommendation, either refer for colonoscopy using the Colonoscopy Referral Form or refer for FIT using the Standard Lab Requisition.​

Personal history of colorectal cancer

​Routine FIT screening is not recommended. Refer for ongoing follow-up with a specialist.

Inflammatory bowel disease (Crohn’s disease, Ulcerative colitis)

R​outine FIT screening is not recommended. Refer for ongoing follow-up with a specialist.​​

High-risk family history of colorectal cancer

One first degree relative (parent, child, full sibling) with colorectal cancer diagnosed under age 60; or Two or more first degree relatives with colorectal cancer diagnosed at any age. 

*If one first degree relative diagnosed with colorectal cancer over age 60, screen as average risk.

  • Routine FIT screening is not recommended. Colonoscopy is recommended every 5 years. Refer for colonoscopy at age 40 or 10 years younger than the age of diagnosis of the patient’s youngest affected relative — whichever is first.

    • ​​​​The youngest affected relative does not have to be a first-degree relative (i.e., can be a grandparent, aunt, uncle, cousin, half-sibling, niece, nephew) but should be on the same side of the family as the first-degree relative with colorectal cancer. 

  • If patient is younger than age 74, refer for colonoscopy using the Colonoscopy Referral Form.

Symptomatic​

All

​​Do not screen. Refer for diagnostic testing.

Symptomatic, includes: 
  • Anemia 
  • Abdominal pain 
  • Rectal bleeding 
  • Change in bowel habits​

​​Management of FIT R​esults 

Patients can sign-up for Health Gateway to get results online. Health Gateway can email and/or text (SMS) patients when new screening letters are added that show they need follow-up or when they are due to screen again.​​

Normal (Negative)

Re-screen with a FIT in 2 years. 

If the patient has a normal result, they can access their result through Health Gateway or by contacting your clinic. The patient will not be notified by mail if their FIT result is normal.

The patient will receive a reminder letter in the mail when it is time for them to screen again.

Abnormal (Positive)

​​​The patient can access their result through Health G​ateway. They will receive their results in the mail within 5 to 10 business days after their sample is returned to the lab.

BC Cancer will facilitate a referral for a colonoscopy to the patient’s Health Authority. The Health Authority will contact the patient, assess their condition, and book a colonoscopy procedure if appropriate, or if other monitoring and/or treatment is advised.​
