If breast cancer recurs after five years, is there a high probability of metastasis?

1. The probability of breast cancer recurrence and metastasis after five years is related to the severity of the disease.

2. Breast cancer is a malignant tumor originating from mammary epithelial cells. According to the TNM system, it can be divided into stage 0, stage I, stage II, stage III, and stage IV. Recurrence after five years means that the patient has relapsed five years after standardized treatment. If the patient is in stage 0 before surgery, and there is no lymph node metastasis or distant metastasis in stage IA and IB, the recurrence five years after treatment can still remain in the previous stage, and the probability of metastasis is small. However, if the patient has reached stage IIA, IIB, IIIA, IIIB, IIIC, and IV before surgery, lymph node metastasis or distant metastasis has occurred during this period. Standardized treatment generally cannot completely remove cancer cells, and they can metastasize to form new metastatic foci after recurrence.

3. After breast cancer patients relapse, they should undergo mastectomy, radical mastectomy, extended radical mastectomy and other surgeries to remove cancerous tissues in a timely manner. At the same time, they can combine chemotherapy, radiotherapy and targeted therapy to remove cancerous tissues. If necessary, they can also choose anti-estrogen drugs such as moxifen and torimifene, as well as aromatase inhibitors such as letrozole and anastrozole to block the effects of estrogen and inhibit the growth of cancer cells.
