Final answer:
To perform a breast self-exam, use finger pads of the three middle fingers in a circular motion, covering the entire breast area to detect any changes, aiding in early detection and treatment of breast cancer.
Step-by-step explanation:
When performing a breast self-exam, it is recommended to use the finger pads of the three middle fingers, as the skin on these areas is highly sensitive and thicker, which improves the ability to detect any irregularities in the breast tissue. The proper technique involves moving the finger pads in a circular motion, covering the entire breast area systematically to ensure no part is missed. It's considered a useful practice for young women to start monthly self-exams to become familiar with their breasts and to detect any changes, such as lumps, which may indicate breast cancer. The outcome is better if breast cancer is discovered and treated early, hence the importance of regular self-exams.
