1. Visual Inspection: Stand in front of a mirror with your shoulders straight and arms on your hips. Look for any changes in the shape, size, or color of your breasts. 2. Physical Examination: Raise your arms and look for the same changes. Next, feel your breasts while lying down, using a firm, smooth touch with the first few fingers of your hand. Follow a pattern to ensure you cover the entire breast. Finally, feel your breasts while standing or sitting, which might be easiest in the shower.
