What are the key clinical features to differentiate between cyclical and non-cyclical breast pain in a primary care setting?

Key clinical features to differentiate cyclical from non-cyclical breast pain in primary care include:

• Timing in relation to menstrual cycle: Cyclical breast pain typically occurs from the luteal phase to the onset of menstruation and resolves with the period, whereas non-cyclical breast pain does not follow a menstrual pattern and can occur at any time.
• Age and hormonal status: Cyclical pain usually affects women from puberty onwards and is associated with hormonal fluctuations, while non-cyclical pain can occur at any age and is often unrelated to hormonal changes.
• Location and nature of pain: Cyclical pain is often bilateral, diffuse, and described as a heaviness or aching sensation, whereas non-cyclical pain tends to be unilateral, localized, sharp, or burning.
• Associated symptoms: Cyclical pain may be accompanied by other premenstrual symptoms such as breast swelling and tenderness, while non-cyclical pain may be linked to other causes like trauma, infection, or musculoskeletal issues.
• Response to treatment and diary keeping: A pain diary documenting timing and severity can help differentiate the two types; cyclical pain often responds to supportive measures and simple analgesia, whereas non-cyclical pain may require further investigation if persistent or severe.

These features guide reassurance and management in primary care, with referral considered if pain is severe, persistent, or associated with other concerning signs.
