Genetic diagnosis in the field of oncology
Between 5 and 10% of cancer patients have a hereditary tumour disease. In these cases, early detection of a genetic disposition:
- Allows appropriate measures to be taken for prevention.
- Allows appropriate measures to be taken for the early detection of the disease.
- It is the basis for individual risk scores.
- It is the basis for a prognostic assessment.
- Therapeutic relevance (personalised cancer medicine or precision medicine).
- Allows to find out if the person has mutations that can transmit an increased risk of cancer to their descendants.
The detection of a genetic predisposition can offer patients access to preventive measures, early detection methods and proactive treatment. In this way, physicians can optimise the health and prognosis of their patients.

What types of hereditary cancer are there?
The most common hereditary cancers are breast and ovarian cancer, colorectal cancer and prostate cancer.
Approximately one in eight women (12.5%) will develop breast cancer in her lifetime. Ovarian cancer affects one in 72 women.
Between 5-10% of breast and ovarian cancers are hereditary and the associated mutations are found in the BRCA1, BRCA2, RAD51C, RAD51D, CHEK2, ATM, BRIP1, PALB2, TP53, CDH1 and BARD1 genes. These genes can be tested for in at-risk families.
The lifetime risk of colorectal cancer in the general population is approximately 1 in 23 (4.3%) for men and 1 in 25 (4.0%) for women. However, this risk can increase by a factor of 4 if there is a family history of colon or rectal cancer.
The two most common syndromes are familial adenomatous polyposis (FAP) and Lynch syndrome (also known as hereditary non-polyposis colon cancer, HNPCC). Other types of hereditary colorectal cancer include juvenile polyposis syndrome, serrated polyposis syndrome, Cowden syndrome, MUTYH-associated polyposis syndrome and Peutz-Jeghers syndrome.
