There are warning signs of cancer's return that you can continue to check for in your unaffected breast, as well as your treated breast. Recurrent breast cancer can cause one or more symptoms, or it can cause none at all.

CHANGES IN YOUR BREAST - POSSIBLE LOCAL CANCER RECURRENCE:
A lump or thickening in your breast or under your arm.
A change in the size or shape of your breast.
Discharge from your nipple, if it comes out by itself and stains your clothing.
A change in the color or feel of the skin of your breast or nipple (such as dimpling, puckering, or scaliness).

CHANGES IN THE WAY YOU FEEL - POSSIBLE SYSTEMIC CANCER RECURRENCE:
Bone pain, fatigue, weight loss, chronic cough, generally poor health.

You should see your health care provider if you notice any changes in your breasts or other parts of your body. The changes may be caused by cancer, or they may be simply be caused by other, less serious problems. One of the greatest challenges in this part of your recovery is to find a balance about how you feel. Every ache and pain does not mean your cancer has come back, but it's important to be cautious about how you feel - without feeling paranoid.
