International Board of Certified Lactation Consultant (IBCLC) Practice Exam

Which of the following conditions is characterized by a deficit in breast tissue development?

1. Mastitis

2. Hypoplasia

3. Galactorrhea

4. Agalactia

The correct answer is: Hypoplasia

Hypoplasia is characterized by underdevelopment or inadequate formation of breast tissue, which can result in insufficient milk production during lactation. This condition is significant for lactation consultants and healthcare providers because it impacts a person's ability to breastfeed successfully. Individuals with hypoplasia may have a history of insufficient glandular development, which can manifest as reduced breast size and insufficient mammary gland functionality. Mastitis refers to an infection of the breast tissue and is not related to the development of breast tissue itself. Galactorrhea is the condition of leaking breast milk not associated with breastfeeding and does not imply a lack of breast tissue development. Agalactia indicates an absence of milk production, but this can result from various factors, including hormonal imbalances or insufficient stimulation, rather than direct underdevelopment of breast tissue. Understanding these distinctions helps in identifying and managing breastfeeding challenges effectively.
