There are no types of I&D as such, but breast abscesses themselves are classified as:
Lactational Abscess: Occurs during breastfeeding due to milk stasis and bacterial infection.
Non-Lactational Abscess: Seen in non-breastfeeding women, often associated with conditions like duct ectasia, smoking, or diabetes.
Treatment for both involves incision and drainage, though ultrasound-guided needle aspiration may be used in smaller abscesses as an alternative in select cases.
