Answer 2

In 1966, Dr. Leon Goldman, considered the " Father of Laser Medicine ", who worked for much of his career as a dermatologist at the University of Cincinnati, supervised the first operation in which a laser ( ruby laser ) was used to remove a tumor without causing bleeding.

However, it wasn't until early in the 1980’s that major advances were made in laser surgery as lasers were developed and utilized based on the principle of selective photothermolysis. Thus specific targets in the skin could be destroyed without damaging surrounding skin structure and minimizing any risk of scarring.

Good Luck !
