How many times should breast cancer targeting be done

How many times should breast cancer targeting be performed?

The targeted treatment time for breast cancer patients after the initial diagnosis is the first year after surgery. In general, the treatment is to use drugs once every 3 weeks, and a total of 17 treatments are required. However, the specific medication situation needs to be analyzed and judged in combination with the patient's pathological type, molecular typing and other comprehensive conditions. It is recommended that patients must listen to the advice of professional doctors for standardized diagnosis and treatment.

For some patients with advanced breast cancer or recurrent metastasis, if chemotherapy and endocrine therapy are ineffective, they can choose targeted therapy. However, the number of targeted therapies is not completely based on the cycle of the initial treatment plan, but requires the doctor to formulate a treatment plan based on the patient's condition. During targeted therapy, these patients need to undergo strict review, observe changes in various indicators, and undergo long-term continuous targeted therapy until clinical indications of treatment failure, then targeted drug treatment can be stopped. The number of times these patients receive targeted therapy cannot be determined.

Targeted therapy for HER-2 positive patients can be used in combination with radiotherapy and chemotherapy to more accurately locate the target and exert an anti-tumor effect.
