This stamp was issued on 19 December 2011 by the postal authority of Ecuador, with an anti-cancer theme. On the top right corner shows St George killing the dragon, the symbol for SOLCA (Sociedad de Lucha Contra el Cáncer del Ecuador), the Ecuadorian Anti-Cancer Society. The wordings (in Spanish) to the left are probably the society's campaign motto - Cancer occurs when you least expect it / Check for it today / Early detection is the cure. The background illustration shows a histological image of tissue, usually taken from biopsies conducted during screening for cancer; the biopsied tissues may be stained according to the type of cancer to be screened and then examined under a microscope by a pathologist, the stained tissues would also be typically photographed under microscope and stored for further examination.
