Juvederm before or after lesion removal?

Hi. Just scheduled an appt for fillers and then found out I need to have a precancerous lesion removed above my lip. The fillers were for the marionette lines. Since the fillers aren’t going in the same place is it better to get the fillers then proceed with the surgery or vice versa. If the surgery is first how long do I wait to get the fillers. The dermatologist did say I could wait a few months to have the surgery done Thank you
