Some examples of the common malignant tumors of hereditary nature:

Mammary carcinoma, ovarian cancer, endometrial cancer, colorectal cancer, gastric cancer, gastrointestinal stromal tumors, renal cell carcinoma, pancreatic cancer, bladder cancer, prostate cancer, non-small cell lung cancer, small cell lung cancer.
Chondrosarcoma, desmoid tumor, leiomyosarcoma, tuberous sclerosis, hereditary multiple exostosis.
Thyroid adenocarcinoma, medullary carcinoma of thyroid, parathyroid carcinoma, multiple endocrine neoplasia.
Melanoma, leukemia, non- Hodgkin's lymphoma.
Neuroglioma, pituitary adenoma, retinoblastoma, neurofibromatosis, pheochromocytoma.

Testing cases:

  The first case of the third generation in vitro fertilized infant in China was born in Shanghai via single-cell high-throughput sequencing technique. The infant’s father was a patient with thyroid carcinoma and there is 50% chance to pass his pathogenic gene to the next generation. The medical specialists blocked the opportunity of the spreading of the familial thyroid cancers through genetic screening and sequencing techniques.

  Angelina Jolie’s mother died from breast cancer at age 56. As a family member of high cancer risk to proactively prevent cancer development, Angelina Jolie received genetic testing for driven genes of breast cancers. After knowing she got the genetic mutation of BRCA1 gene from her mother, which increased her risk of suffering from breast cancers before 70 years old by 50~80% and her chance of developing ovarian cancer by up to 24-40%, finally, under the doctor's advices, she accepted a mastectomy and oophorectomy to reduce her risk of developing malignant cancers
