Caring for you and your family with our reliable breast cancer testing
Not all forms of breast cancer are passed on through the family. However, inheriting a "faulty" version of a breast cancer gene puts you at greater risk of developing the disease. Genetic testing can help save lives.
What causes breast cancer?
Breast cancer is common and, despite new treatments and prevention steps, it still has a high mortality rate. The majority of cases are not hereditary, but in up to 10% of affected individuals there is an underlying genetic alteration. There are a number of genes that are linked to breast cancer; if a person carries an alteration in one of them their risk of developing the disease is high.
How does genetic testing help?
If anyone in your family has been diagnosed with breast cancer you could be at a higher risk of it as well. Genetic testing allows you to define this risk and if necessary make important decisions for your health. If you have already been diagnosed with breast cancer, identifying a genetic involvement can help to monitor and guide targeted treatment.
How is it tested?
A simple blood test can identify whether you have a disease-causing alteration in one of the known breast cancer genes. Highly trained medical scientists and geneticists analyze the DNA and assess each and every alteration detected.
What a positive result means
If the test identifies a predisposition to breast cancer this does not necessarily mean that you have cancer, or will develop it.
Depending on the gene and the alteration, you may have an increased likelihood of developing cancer of up to 80% over your lifetime, but it might also depend on the individual circumstances. Knowing your individual risk will allow you to decide on possible regular cancer screening, chemoprevention or surgery to address the risk. All options should be carefully discussed with your doctor to decide what is best for you.
For those who have a diagnosis of breast cancer, the identification of a genetic alteration can lead to treatments specific to your individual cancer.
Consult your doctor
The information obtained from genetic testing can have a profound impact on your life. Prior to any genetic testing, we strongly recommend that you seek genetic counseling to understand more about which of the following options might be beneficial for you and your family members. Genetic counseling is also recommended to help you understand your genetic test results and their implications for other family members.
At CENTOGENE, we only accept genetic tests ordered by a doctor on your behalf, to ensure that you have access to full support and backup to make informed decisions about your future healthcare.
