Definition
缺损 means 'to be damaged, worn, or missing' — used for physical objects (a broken edge, a torn page) and in medical contexts for a physiological defect (先天性心脏缺损). It is a formal, somewhat technical verb; you won't use it for everyday minor damage like a scratch. Note that the dictionary also lists 'wane' which is rarely used for this word; focus on the damage/defect sense.
