A visible abnormal structural change in a body part.

A visible abnormal structural change in a body part.

• A. LESION
• B. AVASCULAR
• C. AQUEOUS
• D. ANTINEOPLASTIC

Answer: (A)

A lesion is a visible abnormal structural change in a body part. It refers to any area where tissue architecture has been altered by disease, injury, infection, or a tumor, and that can be observed clinically or on imaging. The other terms don’t describe a structural change: avascular means lacking blood vessels or blood supply, which is about circulation; aqueous refers to the clear fluid in the eye, not a structural alteration; antineoplastic describes therapy or properties aimed at tumors, not a visible tissue change. So, lesion best fits the description.
