A breast lumpLump:

However, a change to the breast does not necessarily mean that you have breast cancer. In fact, most breast changes are not breast cancer. More information is needed to properly diagnose the signs or symptoms you are experiencing.

Diagnostic Imaging and Biopsy

The first step used for diagnosis will most likely be an imaging technique, which is a way to get a better picture of what is happening in the breast. You may also need to have a biopsyBiopsy:
A procedure in which tissue samples are removed from the body for examination under a microscope to determine if cancer or other abnormal cells are present.
, where a small tissue sample is taken to be tested in a lab to see if it is cancer.

It is important to diagnose the condition promptly. If it does turn out to be breast cancer, earlier detection can lead to more treatment options and a better chance of surviving the disease.
