Injury or wound (6)
I believe the answer is:
lesion
This clue is a double definition.
'injury' is the first definition.
(I know that lesion is a type of injury)
'wound' is the second definition.
(medical term for a wound)
(Other definitions for lesion that I've seen before include "Flesh wound" , "Abrasion" , "Damaged area of tissue" , "Damage to tissue from injury or disease" , "Harmful change in bodily tissue as from injury" .)
