when a charge particle is moving in electric and magnetic field, a force exert on this particle is Lorentz force.

when this force apply to this particle, it accelerate and we know accelerated charge particle radiate.

when a particle radiate an electromagnetic wave ( photon ) lose it's energy.

it seems that Lorentz force should be modify to describe particle's radiation!

is it true?

Your line of thought is essentially correct within the framework of Classical Electrodynamics.

The force you are referring to is called radiation reaction force or Abraham-Lorentz force.
