There is no exact standard for the chance of breast cancer recurrence after anastrozole is discontinued, and it is related to the severity of the disease and the treatment plan after discontinuing the drug.
Anastrozole belongs to the endocrine therapy drugs, which can be used in the advanced stage of breast cancer, and can also be used as an adjuvant treatment for postmenopausal estrogen receptor-positive early breast cancer.
Generally speaking, cancer cells have already metastasized in the body of late-stage breast cancer patients, so recurrence is very easy to occur after stopping the drug. On the other hand, if early stage patients use Anastrozole to consolidate their condition after surgery, then the chance of recurrence after stopping the drug is relatively low.
In addition, if the drug is discontinued according to the doctor’s instructions, and there is a targeted follow-up program, the recurrence rate can usually be reduced. If the medication is discontinued, the chance of breast cancer recurrence is high and the disease will continue to worsen.
To summarize, there are many reasons for the recurrence of breast cancer, so if you want to know the recurrence rate, you should go to the hospital as soon as possible for checkups and make a reasonable prediction according to your own situation.
