Every year, around 42,000 people in Switzerland develop cancer – primarily breast, prostate, lung, intestinal, or skin cancer. The causes of cancer are very complex. However, in five to ten percent of cases, a higher risk of cancer is caused by hereditary gene variants (mutations).

Added value of genetic testing

  • More precise diagnosis with specific choice of therapy
  • Early introduction of preventive measures (e.g., close medical care) 
  • More precise prognosis of the course of the disease
  • Reliable information for other family members 

What is genetic testing in the field of cancer all about?

Genetic counselling and analysis in the field of cancer (oncogenetics) enable a more precise prognosis of the course of the disease in the case of an existing cancer – regardless of whether it is genetically caused – and allow the choice of a targeted therapy. In addition, genetic counselling and analysis can determine the risk of hereditary cancer in those affected and their relatives. Based on the findings, effective preventive measures can be initiated. The detection of therapy-relevant gene variants allows a patient-specific therapy with the best possible effect and as few side effects as possible.

Which genes are tested?

More than 300 different genes associated with cancer are already known today.

The best-known genes relate to the following cancers:

  • Breast and ovarian cancer
  • Prostate cancer
  • Lung cancer
  • Bowel cancer
  • Pancreatic cancer
  • Skin cancer

When can genetic counselling be helpful in the field of cancer?

Together with the attending physician, the experts assess the added value of genetic analysis for the person concerned during the first counselling session. The following factors, among others, play a role in this assessment:

When cancer occurs at a young age (< 50).

  • If paired organs (breast or ovaries) are affected by cancer on both sides.
  • If there is a specific cancer that has already occurred in other family members.
  • If cancer is known to run in the family and occurred at a young age.

Extensive genetic counselling and a comprehensive family history before the test are essential, as is the counselling session after the test to discuss the results. 

If you have already been diagnosed with cancer or are already undergoing cancer treatment and feel that the medication is not working properly or is causing unwanted side effects, a genetic test in the area of drug efficacy may be of help.

How does genetic counselling and testing work?

  1. Initial consultation between the attending physician or Precise expert and the patient to discuss the genes to be tested and to explain the patient’s rights. At the end of the consultation, written consent is given and the blood sample is taken.
  2. Genetic analysis including evaluation in the Precise laboratory and writing of a clinically oriented report of findings.
  3. Second consultation between the attending physician or Precise expert and the patient to discuss the findings, including classification of the findings in the overall treatment process and discussion of suitable preventive measures and/or treatment options.

Cost coverage

Genetic counselling is covered by basic health insurance as a normal medical consultation and is billed via Tarmed. For the genetic analysis, a cost approval is submitted to the health insurance company. The analysis is covered if the results are indicative for medical treatment. In the context of prevention, oncogenetics for certain cancers is covered for family members. In addition, the consultation and analysis is covered as an innovation factor by certain supplementary insurances. Contact your health insurance for more detailed information on your cost coverage.
