Genetic counselling is a specialised and essential part of oncology care that assesses a patient’s genetic predisposition to cancer and provides them with information, emotional support, and guidance to make informed healthcare decisions.
Personal and family medical history is examined before cancer genetic counselling. The counsellor discusses numerous generations of cancer and its forms. This review helps detect patterns that may indicate a hereditary cancer syndrome, which is caused by gene mutations that raise cancer risk.
After identifying a familial cancer risk, the genetic counsellor discusses genetic testing with the patient. Mutations in cancer-susceptibility genes are detected through genetic testing. The counsellor discusses genetic testing's pros, cons, and the risk of hereditary cancer.
If the patient wishes to undergo genetic testing, the counsellor helps gather blood or saliva samples and coordinates with a genetics laboratory for examination. After the results are obtained, the counsellor helps the patient understand them.
Genetic counselling for cancer patients must address how genetic test results affect cancer risk management and therapy. If a mutation is found, the counsellor collaborates with the patient and healthcare team to create a risk management and surveillance strategy. More frequent cancer screenings, risk-reducing operations, chemoprevention, or targeted therapy may be used.
Genetic counsellors support patients and families emotionally throughout the process. They discuss the psychological and emotional effects of finding about a hereditary cancer risk and how to tell family members who may be at danger.
Genetic counselling evolves as genetics and cancer risk information changes. As genetics and cancer research advance, patients may receive assistance and updates.
In conclusion, cancer patients receive genetic counselling to identify genetic cancer risk, facilitate genetic testing, interpret results, and create personalized risk management and treatment regimens. Patients and their families receive emotional support as they traverse the challenging and often emotional road of genetic cancer risk.
