Genetic Counselling

Genetic counseling consists in informing, educating and supporting people and families who have a genetic disease or have a risk of suffering it. During genetic counseling (online or face to face), the doctor informs the person and family about risks, providing diagnostic and susceptibility tests and proposing actions, also explaining the risks for future generations, and proposing different treatments or preventive measures.

1. Goals of genetic counseling:

According to the American Society of Human Genetics, genetic counseling´s objectives are:

Report about diagnostic, prognostic and treatment of the genetic disorder.

Allowing the understanding of the hereditary mechanism and the probability or risk it represents for other family members.

Propose different reproductive options to reduce the risk.

To favor the individual choice of acceptable options, according to personal perception of risk, goals, and values.

Facilitate adaptation to the presence of the disorder and the risk of recurrence.

2. Who can benefit from a genetic test?

Anyone who, through a DNA test or not, is aware that there are several cases of cancer in their family should visit their primary care physician for an initial assessment. If your doctor considers that there is data suggesting a hereditary disorder, he/she should refer you to the nearest genetic counseling unit. In addition, these products can be useful for those who want to know more about their genetic information, their genetic vulnerability to developing certain health conditions, those who want to know if their medication or drug might be the right one, and who want to know if they are carriers of various hereditary conditions, in order not to pass them on to their offspring.

3. Indications for genetic counseling:

To know if you are a carrier of any hereditary condition or have a genetic vulnerability to developing hereditary cancer

Confirmation of a previous clinical diagnostic.

Family history of hereditary diseases or congenital anomalies.

Family planning. Defining reproductive risk.
