Which symptom is characteristic of fibrocystic breast changes?

Fibrocystic breast changes are commonly associated with cyclic breast pain and tenderness, particularly in relation to the menstrual cycle. Women often report that lumps in their breasts become more pronounced or tender during the premenstrual phase due to hormonal fluctuations. This symptom is quite characteristic of fibrocystic changes and distinguishes them from other breast conditions.

The presence of tenderness in the lumps makes option C the most accurate representation of fibrocystic breast changes. These changes can lead to the formation of fluid-filled cysts or fibrous tissue, which are often influenced by hormonal levels during the menstrual cycle, causing discomfort that typically resolves after menstruation.

The other options describe symptoms that do not align with the typical presentation of fibrocystic changes. For example, a smooth, hard lump might suggest a different pathology, such as a benign tumor or malignancy. A small, movable lump without pain could imply a benign cyst but lacks the key characteristic of tenderness associated with fibrocystic changes. Leaking fluid from the nipple can signal conditions that require further investigation and are not typical for fibrocystic breast changes. Thus, the correct answer highlights a fundamental aspect of fibrocystic changes, underlining their connection to menstrual cycles and breast tenderness.
