Biopsy After Freezing Mole?

Moles  should always be excised and submitted for pathological examination. We can not afford missing a diagnosis of melanoma. With freezing, laser destruction or destruction of a mole by any means one misses the opportunity for a biobsy and proper diagnosis.

Most likely if your mole was treated with cryotherapy, it was not a mole at all but a seborrheic keratosis. This would be especially true if the mole was treated by a dermatologist. Many lay people will call a seborrheic keratosis a mole when it is not. We also hear them described as warts ( the British incidentally call them seborrheic warts). If there is a question whether a particular lesion is a seborrheic keratosis or mole, the use of a dermatoscope can easily differentiate the two.

Freezing tissue distorts the its histology so much that it usually can make identification very problematic. However, if there is a portion of the lesion still present after a month or so, you can always have this re-biopsied and submitted. Any anxiety over this lesion should be alleviated at that point.
