Learn the normal look and feel of your breasts, and check for changes every month.
Many women have a pattern of lumpiness in their breasts, which is normal.
But if you feel a change or a new lump in your breasts or underarms, ask your doctor to examine the area. A breast exam by a trained medical professional should be part of your regular medical checkup. If it is not, ask for it. It includes visual examination and carefully feeling the entire area of breast tissue. If you are 40 or older, schedule your mammogram close to the time of your clinical breast exam.
