What is the symptom of breast cancer?

Varies. The most obvious is a new or enlarging firm mass. Other symptoms can include skin and/or nipple changes. Rarely a unilateral spontaneous bloody nipple d/c. Any new or concerning findings on self-exam should be brought to the attention of your doctor. Finally, the ultimate goal of early detection is to find breast cancer before "symptoms" present - i.e. Screening mammmography.
Several. New or enlarging lumps, nipple discharge and skin changes are all things that should be investigated to rule out breast cancer. Each of these can be associated with other things but cancer should be ruled out.While many breast cancers do not cause pain, some do: any new, persistent pain in the breast should be evaluated. The best time to DX cancer is before symptoms develop. Mammograms save lives.
