Cryo-ablation (freezing) of sun related skin lesions is absurdly expensive, and if you do not have health insurance you can multiply the charge 2X or 3X times higher.
Millions of skin biopsies could be avoided every year in the USA if Dermos preemptively froze lesions when they first appear.
Instead, most Dermos do nothing until lesions begin to change or grow, at which point they cut them out and send them to the lab - and send you a $750 bill.
If Registered Nurses or Physician Assistants were specially trained in cryo-ablation, one third of Dermatologists would go out of business.
I used to get extensive cryo treatments (non cancer related) in the 90s for $25/visit. They stung pretty bad at times, though.
That happens in my primary office.
