There were a couple of spots on my leg the dermatologist wanted to biopsy. They appeared identical to me, but one of them was nothing and the other was pre-cancerous. The treatment was a blast of freezing liquid nitrogen.

The Liquid Nitrogen instructions:
- A small blister may form on the areas treated. If the blister is large it may be ruptured with a sterilized needle. Sometimes the blister may be hemorrhagic (blood filled).
- It may take anywhere from 2 to 4 weeks for the areas treated to form a scab and fall off.
Hmm. To rupture or not to rupture? I’ll contemplate what to do while awaiting the arrival of Snowzilla.
