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. [1]
His contemporary Nicolaes Tulp believed that cancer was a poison that slowly spreads, and concluded that it was contagious. [6] In the 1600s, cancer was vulgarly called "the wolf[e]". [7] The first cause of cancer was identified by British surgeon Percivall Pott, who discovered in 1775 that cancer of the scrotum was a common disease among ...
The theory about the monoclonal origin of cancer states that, in general, neoplasms arise from a single cell of origin. [1] While it is possible that certain carcinogens may mutate more than one cell at once, the tumor mass usually represents progeny of a single cell, or very few cells. [1]
1900 – Swedish Dr. Stenbeck cures a skin cancer with small doses of radiation [4]; 1920s – Dr. William B. Coley's immunotherapy treatment, regressed tumors in hundreds of cases, the success of Coley's Toxins attracted heavy resistance from his rival and supervisor, Dr. James Ewing, who was an ardent supporter of radiation therapy for cancer.
Another evolutionary theory puts the roots of cancer back to the origin of the eukaryote (nucleated) cell by massive horizontal gene transfer, when the genomes of infecting viruses were cleaved (and thereby attenuated) by the host, but their fragments integrated into the host genome as immune protection. Cancer thus originates when a rare ...
