The exact cure rate of HER-2 positive patients with stage II breast cancer cannot be generalized and is closely related to many factors.
Stage II breast cancer refers to the size of breast lump between 2~5cm, which belongs to the relatively early stage, and actively cooperate with the treatment, the hope of cure is very high.
The cure rate of patients with stage II breast cancer is not only related to the expression of HER-2, but also to the expression of estrogen and progesterone receptors, the degree of histological differentiation of breast cancer, molecular typing, and the assessment of the risk of clinical recurrence, and many other factors.
HER-2 is human epidermal growth factor receptor-2, and HER-2 positivity indicates that breast cancer patients have a higher risk of recurrence and metastasis, which is an indicator of poor prognosis.
Currently, molecular targeted therapy has emerged for HER-2 positive patients, and after treatment, the disease recurrence rate of HER-2 positive early breast cancer patients has been reduced and the cure rate has been significantly improved.
