​Tropic of Anti-Cancer

Hidden away in a valley in Ecuador is the world's largest population of Laron syndrome sufferers. This rare form of dwarfism wasn't thought to have any wider medical significance until local doctor Jaime Guevara started to research the condition. His discovery of apparent immunity to cancer and diabetes in this population has attracted the attention of the international medical community, sparking hopes that a cure to these diseases could be found. RTD follows the doctor and his team as they conduct research into the rare condition that one day may benefit all mankind.
