Genetic Counseling

In 90% of breast cancer cases, no clear cause can be identified. However, factors such as hormone therapy, lifestyle, radiation exposure, obesity, and diet may play a contributing role.

In contrast, approximately 10% of all breast cancers have a clearly identifiable cause. The predisposition to the disease is inherited from one or both parents. An increased incidence of breast cancer across multiple generations, very early onset, or the presence of breast cancer in male family members are strong indicators of a hereditary predisposition to breast cancer. When breast cancer has a genetic origin, there is also an increased risk of cancers in other organs, and close relatives may also be at risk. During genetic counselling, a specialist will assess whether genetic testing is appropriate. If so, the tests are arranged, the results are discussed in detail, and the possible medical, psychological, and familial implications are thoroughly evaluated.
