New nipple inversion indicates what?

• A. Normal postpartum change
• B. Hormonal fluctuations
• C. Possible malignancy
• D. Benign skin lesion

Answer: (C)

New nipple inversion in an adult is a warning sign that suggests a possible malignancy. Breast cancers can involve or tether the tissues around the nipple, pulling it inward as a mass grows or as the cancer invades ducts and Cooper’s ligaments. This retraction is often unilateral and persistent, and it may be the first presenting sign before any lump is felt or skin changes are visible.

Normal postpartum changes or hormonal fluctuations typically cause temporary, bilateral, or non-focal changes rather than a new, unilateral inversion that persists. Benign skin lesions would not usually pull the nipple inward in a way that mimics cancer. Because new-onset inversion can indicate an underlying malignancy, it requires prompt clinical evaluation with breast imaging (such as mammography and ultrasound as age-appropriate) and examination.
