Heredity with reference to carcinoma: As shown by the study of the cases examined in the pathological laboratory of the University of Michigan, 1895-1913.

"In 1895, a young seamstress of his [Warthin's] acquaintance told him about her family's long history of cancer deaths.^[6] Intrigued, he researched her family's history, searching death records and administering questionnaires, and found multiple cases of cancer. He followed the family, which he called "family G", for decades, and in 1913 he published their history in the Archives of Internal Medicine.^[7][8] His article was one of the first to make the case that cancer was heritable in humans, and the medical pedigree of family G (which was later determined to suffer from hereditary nonpolyposis colorectal cancer or Lynch Syndrome) is one of the longest and most detailed cancer genealogies in the world" (Wikipedia article on Alfred Scott Warthin, accessed 06-2017).
