Which statement about breast self-examination is accurate?

• A. Perform breast self-exam weekly starting at age 18.
• B. Perform breast self-exam monthly after menopause.
• C. Perform breast self-exam monthly after age 20, immediately after menstruation or on days 5-7 of the menstrual cycle.
• D. There is no recommendation for breast self-exam.

Answer: (C)

The key idea is that timing a breast self-exam to when the breasts are least affected by hormonal changes makes it easier to notice real changes. Doing the exam monthly after the breasts have stabilized post-menses provides a consistent baseline and improves your ability to detect new lumps.

Specifically, performing the self-exam after puberty and continuing monthly after age 20, with the exam done immediately after menstruation or on days 5–7 of the cycle, is recommended because hormonal cycles cause normal tissue changes that can mask or mimic pathology. Right after menses, the breast tissue is less swollen and tender, making it easier to feel any unusual masses or skin changes.

This approach is not about weekly exams or focusing only after menopause, and while modern guidelines emphasize being familiar with your breasts and reporting any changes promptly, the described timing and frequency reflect traditional guidance that optimizes detection.
