Mole keeps re-appearing after laser YAG treatment. What to do? (photos)

Hi I have already 3-4 laser YAG sessions to remove a mole in my nose. After some months a brown spot appears, my doctor told me that it is the mole appearing again. What can be done to avoid from coming back? Should i keep getting laser sessions? Ps. in the picture is the actual brown little spot now 2-3 months after the last laser session
