I betragtning af, at tacrolimus virker gennem suppression af de T - celler, der er involveret i immunovervågningen, kan tacrolimus dog tænkes at påvirke den videre udvikling af hudforandringer, der enten er præmaligne eller er i et tidligt stadium af malignitet.
However, considering that tacrolimus is effective through its suppression of T cells which are involved in immune surveillance, it is possible that tacrolimus could have an effect on the behaviour of cutaneous lesions which were either pre-malignant or cases of early malignancy.
