Early Detection
Screening is the domain where more is not automatically better. A test can find something that would never have caused harm, and the follow-up carries its own risk. Deciding what to screen for, and when, depends on the person rather than on what is available to order.
What this means for healthspan
Early detection means finding certain conditions before they cause symptoms or lasting harm, when treatment may be simpler or more effective. It is not the same as testing for everything. Many conditions are only worth looking for in people at higher risk, and many tests are only helpful at certain ages.
Screening also has costs. A test can raise a false alarm, lead to follow-up procedures that carry their own risk, or find a condition that would never have caused problems in a person's lifetime (called overdiagnosis). Good early detection weighs these trade-offs for each person.
What we assess, and why
We start with your personal and family history, your age, and your immunization record. From there we look at which screening programs and vaccines apply to you, using published Canadian guidance and BC programs where they exist. We also look for family patterns that may point to an inherited risk.
Where a screening test is not recommended for people at average risk, we say so and explain why. Extra imaging or specialist assessment is considered only when your history or findings give a clear reason, and after we have talked through what the result could change.
What we may assess
Personal and family history, age-appropriate cancer screening, immunization status, relevant physical examinations and hereditary risk where indicated. Additional imaging or specialist assessment may be considered when appropriate.
What is used is chosen for you, according to your individual risk, clinical appropriateness, the evidence and what you decide with your physician.
Why it matters
Evidence-based screening and timely follow-up can help detect selected conditions at a stage when intervention may be more effective.
Examples of assessments and investigations
These are examples of what may be considered. Which of them are used for you depends on your history, your risk and what you decide with your physician.
Personal and family history review
A structured review of past illnesses, relatives with cancer or early heart disease, and exposures such as smoking. It helps decide which screening applies to you and when to start.
Breast cancer screening
Mammography through the BC Cancer program. Recommendations for people in their 40s differ between national guidance and provincial programs, so timing is a shared decision.
Cervix screening
Screening for people with a cervix, using a Pap test or the self-collected option offered through BC Cancer. Eligibility depends on age and past results.
Colorectal cancer screening
A stool test (fecal immunochemical test) at set intervals for most adults in the eligible age range. A colonoscopy may be advised instead for people with a personal or family history that raises risk.
Lung cancer screening
Low-dose CT scanning for people with a significant smoking history, assessed through the BC Cancer lung screening program. It is not for people who have never smoked or who have low risk.
Immunization review
A check of the vaccines recommended for adults in BC, based on your age and health conditions, and whether any are due.
Skin and physical examination
A focused examination guided by your history, for example looking at moles or lumps that you or your clinician have noticed. It is not a substitute for seeing a doctor about a new symptom.
Hereditary risk assessment
Where several relatives have had certain cancers, or cancers at a young age, a referral for genetic counselling may be considered. Testing is offered only when the history supports it.
Additional imaging or specialist referral
Considered only when a symptom, finding or strong family history gives a reason. We do not offer whole-body scans for people without symptoms, because they often find harmless changes that lead to more tests.
What the evidence supports, and where it is uncertain
What the evidence supports
- Organized screening programs for cervix and colorectal cancer, and for breast cancer in the recommended age groups, are supported by Canadian guidance as a way to find disease earlier in people without symptoms.
- Low-dose CT screening may benefit a defined group of people with a heavy smoking history when it is done in a program with proper follow-up.
- Recommended adult vaccines can lower the risk of serious infections, and checking your record is a low-risk part of a visit.
- Family history is a useful way to decide who may need earlier or different screening, and to identify people who may benefit from genetic counselling.
Limits and uncertainties
- Screening can give false positives, which may lead to anxiety, repeat imaging and biopsies for people who turn out not to have cancer.
- Screening can find cancers that would never have caused harm (overdiagnosis), and treating them can still cause side effects.
- Guidelines do not always agree. Recommendations for breast screening in the 40s, and for how often to repeat some tests, differ between national bodies and provincial programs.
- The Canadian Task Force on Preventive Health Care advised against routine PSA blood testing for prostate cancer in men without symptoms (2014 guidance), because the benefit is small and uncertain and false alarms and overtreatment are common. Some men still choose it after a careful talk about the trade-offs.
- Whole-body MRI and similar scans for people without symptoms are not part of routine screening guidance. Evidence of benefit is lacking, and they often find incidental changes that lead to further tests.
From findings to a plan, and what follows
How findings can inform a plan
Findings from your history and any screening can help build a schedule that fits you: which tests are due now, which can wait, and which are not worth doing. If a result is abnormal, we explain what it does and does not mean, and what the next steps could be. Where nothing is recommended, we say so, so that you are not asked to repeat tests that are unlikely to help.
Follow-up, monitoring and coordination
Follow-up may include reminders for screening and vaccines, coordination with BC Cancer programs and your family doctor or nurse practitioner, and referral to specialists if a result needs further assessment. Abnormal results are followed through the appropriate public or private pathway, and we review your plan again if your health, age or family history changes.
What happens here
The approach is the same in every area: establish where you are, change something on a cadence, then measure again to find out whether it worked. In early detection that work is organized into the programs below.
