If you are at risk of breast cancer, perform a self-check once a month. Part 1. Mirror check Stand in front of the mirror and look for changes in skin texture, such as dimpling, puckering, indentations, or skin that looks like an orange peel. Also note the shape and outline of each breast. Check to see if the nipple turns inward. Flex your chest muscles to see if there is any change. Part 2. Shower check Soapy skin makes it easier to do this test. Raise your left arm over your head On your right hand, put your index finger, middle finger, and ring finger together as a group. You will use these three fingers to check your left breast. Check the texture of your left breast by starting at the outer edge. Place your three fingers flat onto your skin, press down and move in small circles. Repeat this all around your breast. Check your nipple by gently squeezing it between your index and ring fingers. Look for any discharge, puckering, or retraction (pulling inward). Repeat for the right. Part 3. Lying-down check Repeat the process from the shower check. Slide 2: female self exam. Slides 3-4: male self exam. Slide 5: symptoms to look for.
