There is no professional statistical data on the recurrence probability of triple-negative breast cancer in the mid-term, according to the current data, about 30~40% or so of the patients will recur within 2~3 years after the operation, and it is necessary to treat in time and review actively. The recurrence probability of triple-negative breast is not higher than that of other types of breast cancer, and its high recurrence time is about 2~3 years after surgery, with a probability of about 20~30%, but if there is no recurrence within five years, the probability of further recurrence will become very small. Triple-negative breast cancer should be actively treated after surgery, and it is not sensitive to endocrine therapy and targeted therapy, but is relatively sensitive to chemotherapy. In addition, it is necessary to actively review and regularly conduct breast ultrasound and other examinations. It is important to seek timely medical treatment for triple-negative breast cancer and actively receive treatment.
