Abstract
We compute the classical and the quantum breaking of the dilatation current in the minimal Lorentz and CPT-violating quantum electrodynamics. At the classical level, scale symmetry is broken by the general mass term \bar{\psi}M\psi and the Chern-Simons-like term. At the quantum level, it is broken by all expected observable fermion operators in the massless limit.
