Most of the signs of breast cancer recurrence will be loss of appetite, weight loss, and discomfort in the chest. If metastasis occurs, such as bone metastasis, it will cause pain in the corresponding area, and liver metastasis will cause pain in the liver area and jaundice. If lung metastasis occurs, it will cause chest tightness and shortness of breath. Therefore, it is recommended that patients pay attention to the diet, eat more fruits, vegetables and high-protein foods, avoid spicy and stimulating foods, and do regular follow-up examinations to determine the latest development of the disease. Diet and work and rest time should be regular to enhance patients’ immunity and strengthen their resistance to cancer cells to reduce the risk of recurrence.
