When to seek medical advice

Although most breast changes aren't cancerous, it's important to have them evaluated promptly. See your doctor if you discover a lump or any of the other warning signs of breast cancer, especially if the changes persist after one menstrual cycle or they change the appearance of your breast. If you've been treated for breast cancer, report any new signs or symptoms immediately. Possible warning signs include a new lump in your breast or a bone ache or pain that doesn't go away after three weeks. In addition, talk to your doctor about developing a breast-screening program, which may vary, depending on your family history and other significant risk factors
