Warning Signs of Breast Cancer

Many of the symptoms of breast cancer can also be symptoms of something else. Only your doctor can tell for sure. If you have any of these, make an appointment with your doctor.

  • A hard, marble-like area under the skin

Your doctor will do tests to find out the cause. He or she can give you the "all clear" or help you start treatment if the tests show you have cancer. Most breast lumps are not cancer. But if your doctor believes it is, it’s best to start treatment right away.
