The new version of the SANCphot integrator has been prepared for fast and stable numerical calculations up to two loops polarized light-by-light scattering. One-loop modules based on helicity formalism with massive particles two-loop massless inside are used. presented study is driven by potential photon beams probe high energy region. This a contribution research program CEPC project being under development in China.
