Breast cancer is one of the most common diseases that threaten the life and health of patients. With advances in medicine, breast cancer treatment has also been able to remove tumors and kill cancer cells. However, breast cancer still has a 10~20% chance of relapse.

Breast cancer is a malignant tumor formed by abnormal division and reproduction of breast tube cells or adenocytes. Breast cancer treatment is mainly the removal of all cancer cells. However, some cancer cells have not been completely removed and have not been detected, and after further reproduction, they have become cancer. After initial treatment, breast cancer may still relapse after months or years. Recurrence of breast cancer can be divided into local recurrence (LRR) and distant metastasis, local relapse if it originates from the same tumor or occurs in the same location. Cancer cells may also spread to other parts of the body, such as lymph nodes, bone marrow or lungs, which are called distant metastases.

Recurrence of breast cancer

Symptoms include new tumors in the breast, breast lumps, inflammation or redness of the breast, flat or even depressed nipples, bleeding from the nipples, pus or other abnormal changes.

Brain

Symptoms of brain metastases in breast cancer include headaches, which are distal metastases that are more severe, longer and more frequent than normal headaches. According to medical experts, these symptoms are also signs of visual impairment and muscle weakness. If breast cancer patients experience severe headaches or other neurological symptoms, they should consult a doctor as soon as possible.

Liver

Remote metastasis may occur before breast cancer surgery, cancer cells have spread to other organs in the body without being removed. Distant metastasis of breast cancer occurs mainly in the liver. Patients often experience changes in appetite and unreasonable weight loss. If you have these symptoms, check for liver metastases as soon as possible. Failure to do so may lead to serious diseases such as liver failure and Liver cancer.

Pulmonary

The lungs may also be affected by breast cancer cell metastases. Symptoms include dyspnea, cough, blood phlegm, etc. Recurrence of breast cancer often occurs in patients after treatment, so recovery is important. Be aware of the signs of recurrence and take good time for early treatment.
