The symptoms of breast cancer recurrence again show different manifestations, as follows: 1. More obvious symptoms: Patients with surgical site nodules are considered to be chest wall recurrence, i.e. hard texture, which can obviously be touched and seen. If brain metastasis occurs, dizziness and vomiting will occur. If lung metastasis occurs, coughing, chest pain, hemoptysis, and dyspnea will occur. If bone metastasis occurs, there will be bone pain at the metastatic site. 2. No obvious symptoms: If the lesion is small and has no obvious symptoms, it needs to be detected by usual follow-up review.
