Breast Cancer ER 95% Positive is an immunohistochemistry test result for breast cancer. The higher the value of ER positivity in a breast cancer patient, the better the chances of survival.
Breast cancer ER95% positive means that the patient’s estrogen receptor positivity is high. The clinical significance is that the level of estrogen receptor in the tumor cells can be derived from the ER test, which can be used to determine whether the patient can take further endocrine treatment. 95% of the patients with high ER expression have better endocrine efficacy.
After the diagnosis of breast cancer, patients need to undergo surgery, and then combined with radiotherapy and chemotherapy to treat, breast cancer ER95% positive value is higher, the patient can use relevant drugs for endocrine therapy, to further improve the survival rate of patients.
For endocrine therapy, tamoxifen is commonly used for premenopausal treatment, and postmenopausal treatment drugs include aromatase inhibitors such as letrozole. The drugs should be used under the guidance of a professional doctor, and should not be used blindly on their own to avoid adverse effects.
