Cancer Genetics Clinics

2026/09/30

Most cancers occur by chance. However, for some individuals and families, cancer may be associated with an inherited gene mutation that increases the risk of developing certain cancers. By identifying a genetic predisposition to cancer, individuals and their families may benefit from more personalised cancer screening, medical care and treatment options.

The Cancer Genetics Clinic at NCIS provides genetic counselling to individuals with a personal and/or family history of cancer. Through a comprehensive assessment of personal and family health history, our team helps patients better understand their inherited cancer risk, explore whether genetic testing may be appropriate, and learn about options for cancer screening, risk management and care.

Cancer genetics service

Genetic evaluation and counselling will be beneficial to you if you have a personal or family history of the following:

Young onset cancer (e.g. breast cancer before age 40 or colon cancer before age 50)
Multiple family members affected by the same type of cancer or related cancers (e.g. breast and ovarian, colon and uterine)
Multiple primary cancers diagnosed in one individualKnown genetic mutation in the family
Rare tumours (e.g. male breast cancer, paraganglioma, medullary thyroid cancer)
Presence of other clinical features associated with an inherited cancer syndrome (e.g. multiple colonic polyps)

Understanding the cancer genetics clinic journey

Patients referred to the cancer genetics service are evaluated and counselled individually or with their family members. During each new consultation, the patient's cancer and family histories are evaluated and an assessment is done.

Patients suspected of having a genetic predisposition of a particular genetic syndrome are counselled on the following:

Genetic education and counselling on suspected genetic syndrome
Discussion of lifetime risks of cancers associated with suspected syndrome • Potential benefits and risks of genetic testing
Personalised screening recommendations for patient and family members
Recommendations on preventive options for cancer prevention
Options for research participation

If genetic testing is indicated, blood can usually be drawn on the same day following the counselling session.
