Breast cancer can recur or come back in three ways:
The cancer can return at the original site. This is called a local recurrence.
The cancer can recur nearby, such as in the chest. This is called a regional recurrence.
The cancer can spread to a distant location in the body, such as lymph nodes, bone marrow, or lungs. This is called a distant recurrence, or a metastasis.
Your doctor will order more tests to see if the breast cancer has spread, beginning with a physical exam and often a biopsy. The doctor is checking to see if cancer is present and, if so, if it is a recurrence of the same type of cancer or a completely new cancer (which is called a second primary cancer.)
