The symptoms of recurrent breast cancer are related to the location and form of recurrence. For example, if breast cancer recurs at the chest wound site, the symptoms typically manifest as local lumps or localized ulcers, erosion, and bleeding. If the recurrence is in the lungs, liver, or brain, it usually appears in the form of tumors. Early lung tumors do not show symptoms, but if it invades the pleura and causes pleural effusion, it can lead to shortness of breath or chest pain. If a tumor grows too large on the liver, it can cause abdominal pain or symptoms like loss of appetite, unwillingness to eat, and other complications associated with liver diseases. If it metastasizes to the head, symptoms such as dizziness, headaches, and a feeling of pressure in the eyes may occur. If it spreads to the bones, it can cause pain in the affected bone or fractures.
