This document provides information on breast self examination including its purposes, timing, procedure, and role of nurses. A breast self exam allows individuals to examine their own breasts for any changes that could indicate breast cancer. It should be performed monthly beginning at age 20. The exam involves visual inspection of each breast in different positions as well as palpation of the breasts using different patterns and pressure levels. Regular self exams can help detect breast cancer early when chances of survival are greatest. Nurses educate women on proper techniques and timing to improve compliance and early detection.
