Genetic Counselling Before Cancer Genetic Testing: What to Expect
By Dr. Gajendra Kumar Himanshu
Genetic counselling before cancer genetic testing is a crucial step to help patients understand what genetic testing may and cannot tell them about their risk of cancer. Genetic testing is often done because of a personal experience of cancer, a strong family history of cancer, or concern about inherited abnormalities in genes that cause cancer. Before any testing is done, a genetic counsellor or other health care expert will explain how genetic testing is performed, what the possible results might indicate, how the results could influence treatment or future screening, and whether family members might also be affected.
This discussion helps people make informed decisions and feel better prepared for the testing procedure. Remember that genetic testing is not for everyone. Decisions should be made based on individual risk, family history, genetic testing factors, overall health and the doctor’s advice.
In this blog, we will talk about what genetic counselling is, why it is suggested before cancer genetic testing, what happens during the meeting, and how it helps patients and families make informed healthcare decisions.
What is Genetic Counselling?
Genetic counselling is a talk with a health care provider trained in genetics and hereditary health issues. The objective is to encourage individuals to understand:
- When genetic testing may be advised
- What testing can tell us
- Possible benefits and drawbacks
- Implications for future healthcare choices
- Whether family members may also be affected
Genetic counselling is intended to inform and support, not to pressure for testing.
Genetic Counselling: A Must Before Testing
Cancer genetics testing can provide significant information, but sometimes the results are confusing. Genetic counselling helps people understand before testing:
- What the exam is trying to find
- What a positive result might mean
- What a negative result might mean
- The risk of unknown results
- How testing might affect treatment or screening plans
Knowing this information ahead of time typically helps to lessen confusion and anxiety later on.
Who Can Be Offered Genetic Counselling?
Not everyone should have cancer genetic testing. Doctors may recommend genetic counselling for persons who have:
- A positive family history of cancer
- A younger age of cancer diagnosis
- Several malignancies in the same family
- Uncommon cancer types
- Relatives known to have inherited a genetic mutation
What is right depends on your unique situation and medical history.
What to Expect at a Genetic Counselling Visit?
The appointment is usually a talk, not a medical treatment.
Family History Review
One of the most significant portions of the session is discussing family medical history. The counsellor could ask about:
- Brothers, sisters, children, parents
- Grandparents and other relatives
- Family history of cancer
- Age at diagnosis
- Prior genetic testing results
This information is useful to see if there are any inherited factors.
Discussing Your Medical History
The healthcare provider may also look at:
- History of cancer
- Existing therapies
- Medical problems
- History of screening
- General health
All this helps guide recommendations.
Understanding Potential Test Results
Patients are often startled to hear that genetic test results are not always clear-cut. You can get:
- A genetic alteration associated with cancer risk
- No major genetic alterations found
- Inconclusive results that need more analysis
The counsellor discusses each possibility before testing is done.

The Emotional Aspects of Genetic Testing
When you think about inherited cancer risk, there can be a lot of feelings that come up.
Some may feel:
- Curious
- Concerned
- Hopeful
- Uncertain
- Overwhelmed
These feelings are quite natural.
Support might be from:
- Relatives

Often, just keeping the lines of communication open can make people feel more secure through the process.
How Might Results of Genetic Tests Be Used
If tests are done, the results may help doctors decide about:
- Screening intervals for cancer
- Plans for future monitoring
- In some cases, treatment choices
- Assessment of the risk to relatives
But no decision is made based on genetic testing alone.
Doctors also take into account:
- Personal risk factors
- Genetic influences
- General health
- Present medical condition

- Medical advice
