Should I opt for breast reduction or build up

the options may change when further results are in but my surgeon said I could have either a breast reduction or take skin from my back to build the breast up . A breast reduction means a second op next year as they only do one breast before radiation and then match the other a year later .. my thinking has changed a few times .. I don’t mind about the scar and if would be good to have it all sorted .. but I recently read a breast reduction may reduce future risk so could be worth considering for that .. would appreciate any thoughts of anyone else had similar options
