Breast self-examinations are personal checks of your breasts from time to time to look for breast cancer. However, breast self-examinations are not recommended because they may not be very useful. It may be difficult for you to feel small spots or lumps that are actually signs of cancer. Instead, you should practice breast self-awareness and let your doctor know if you notice a change or problem with your breasts. You can feel your breasts while you're in the shower, and if you notice anything different, tell your doctor. This can include new pain, a mass, nipple changes, or any redness in your breasts.
