Investigadores del Amarsham Hospital (Reino Unido) escriben que los perros pueden ser entrenados para detectar este tumor olfateando muestras de orina, ya que produce sustancias orgánicas volátiles con olores distintivos, incluso a concentraciones mínimas.
Su estudio consistió en tomar muestras de orina de 36 pacientes con cáncer de vejiga, que fueron comparadas con las de 108 personas sin cáncer. Los autores entrenaron seis perros de diferentes razas durante 7 meses. Cada uno tuvo que olfatear 7 muestras –una procedente de un paciente con cáncer y seis de personas sanas-. Globalmente, los animales acertaron en 22 de 54 ocasiones, lo que representa una tasa de éxito del 41%, cuando la proporción de aciertos por azar habría sido del 14%.
