Is a localized collection of pus called an abscess?

Yes, an abscess is a localized collection of pus that forms in response to an infection. It is characterized by the accumulation of dead tissue, white blood cells, bacteria, and other debris at the site of infection. Abscesses can occur in any part of the body, but they are most commonly found in the skin, lungs, abdomen, and oral cavity. Treatment typically involves draining the abscess and administering antibiotics to eliminate the underlying infection.
