Key points

  • Hereditary genetic factors are responsible for a considerable part of gynecological malignancies.

  • Knowing these factors enables precision prevention.

  • Non-HPV-associated cervical adenocarcinomas (NHPVA) are diseases related to hereditary genetic factors.

  • Among endometrial carcinomas, 3%-5% are hereditary (Lynch syndrome) and in half of cases they precede colorectal cancer, which is the most detected.

  • Ovarian, tubal and peritoneal high-grade serous carcinomas originate in the epithelium of the tubal fimbriae.

  • Approximately 20% of ovarian carcinomas are hereditary.

  • Pathogenic mutations of BRCA1 and BRCA2 genes are more frequent in ovarian cancer, but other genes are also related to this disease.

  • The identification of individuals at hereditary risk for gynecological cancer and prophylaxis are the most efficient measures.

  • Assessment of family history and appropriate genetic tests interpreted by qualified professionals are cost-effective.

  • Clinical therapeutic measures and prophylactic surgeries are part of the resources for prevention of hereditary gynecological cancer.
