During the 40s, Dr. Juan Tanca Marengo, a distinguished Ecuadorian doctor and humanist, worried about public health and all the different types of cancer, considered that it was necessary for him to share his oncologic knowledge with the medicine students and with doctors in general. His purpose was to establish prevention and healing campaigns, through the creation of an institute dedicated to the fight against cancer. December 7 of 1951, he calls a group of his closest doctor friends to found one of the public works with the most transcendence in Ecuador: the Sociedad de Lucha contra el cancer, or SOLCA.
