There is no authoritative information about the survival period of advanced triple-negative breast cancer, which may be 1~2 years or a few months, and the specific time needs to be determined according to the actual condition, which varies from person to person. Triple-negative breast cancer is a special type of breast cancer, and there is no authoritative information on the survival period of triple-negative breast cancer. Although, this disease has certain sensitivity to chemotherapy, after conventional treatment, the prognosis is still poor, so in general, the survival period of advanced triple-negative breast cancer is as long as 1~2 years, or as short as a few months, and there is a high recurrence rate and distant metastasis. Due to the difference of each patient’s actual condition, physical quality, treatment plan and other factors, the specific survival period of advanced stage triple-negative breast cancer has obvious individual differences and cannot be generalized. To summarize, triple-negative breast cancer patients need to go to the hospital in time and cooperate with doctors for active treatment. Secondly, they should have regular follow-ups so that doctors can understand the changes in their condition and adjust the treatment plan.
