  We investigate the predictions for lepton flavour number violating processes
in the context of a simple left-right symmetric theory. In this context
neutrinos are Majorana fermions and their masses are generated at the quantum
level through the Zee mechanism using the simplest Higgs sector. We show that
the right handed neutrinos are generically light and can give rise to large
lepton number violating contributions to rare processes. We discuss the
correlation between the collider constrains and the predictions for lepton
number violating processes. We find that using the predictions for mu to e
gamma and mu to e conversion together with the collider signatures one could
test this theory in the near future.
