Can I use the at home freeze off method for a large mole on my buttocks? (Photo)

After i gave birth 3 years ago i had a skin tag show up on my buttocks. About one year later it changed into a round mole then it changed again recently into a quite larger mole and it is unsightly. I have had it looked at by a doctor and she told me it's not a cyst, doesn't look like a mole nor a wart and she wasn't sure what it is. My blood work showed all my white and red blood counts are perfect and nothing was abnormal.
