  • In addition, the Cambridge Dictionary says ablation can also refer to a medical treatment that involves cutting away a small amount of tissue from the body. 
  • The Oxford English Dictionary defines ablation as surgery to remove body tissue, the erosion of rock, typically by wind actions, and the loss of surface material from a spacecraft or meteorite through melting or evaporation caused by friction with the atmosphere.  
  • When used as a noun, Dictionary.com defines ablation as the removal — especially of abnormal growths, organs, or harmful substances — from the body by mechanical means via surgery.
