Neoteny and reduction in skull size – grey wolf and chihuahua skulls. When the role of dogs expanded from just being working dogs to also being companions, humans started selective breeding dogs for morphological neoteny, and this selective breeding for "neoteny or paedomorphism" "strengthened the human-canine bond."
Neotenic complex syndrome (NCS) is a syndrome that presents as an extreme form of developmental delay, with the defining characteristic being neoteny of the patient. It was named in 2017 by Dr. Richard F. Walker, who discovered several genes implicated in the syndrome.
Neoteny is the retention of juvenile traits well into adulthood. In humans, this trend is greatly amplified, especially when compared to non-human primates.
Familial adenomatous polyposis is a cancer syndrome in which there are hundreds to thousands of benign adenomas in the colon.. A hereditary cancer syndrome (familial/family cancer syndrome, inherited cancer syndrome, cancer predisposition syndrome, cancer syndrome, etc.) is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the ...
Drawing from ideas of neoteny, Shepard postulated that many humans in post-agricultural society are often not fully mature, but are trapped in infantilism or an adolescent state. He died of lung cancer on July 21, 1996, in Salt Lake City. [2]
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria.

An H&E stain of tissue from a chromophobe renal cell carcinoma, the second-most common cancer associated with BHD. People over 20 years of age with BHD have an increased risk of developing slow-growing kidney tumors (chromophobe renal carcinoma and renal oncocytoma), kidney cysts, and possibly tumors in other organs and tissues.

Field cancerization or field effect (also termed field change, field change cancerization, field carcinogenesis, cancer field effect or premalignant field defect) is a biological process in which large areas of cells at a tissue surface or within an organ are affected by carcinogenic alterations. The process arises from exposure to an injurious ...
