How many years can you take Fulvestrant?

Fulvestrant (Fulvestrant) is a drug for the treatment of breast cancer. It is generally used for more than five years, but the specific number of years it can last varies depending on the patient's condition and personal constitution. Tumor growth in some breast cancer patients is stimulated by estrogen, and fulvestrant can compete with estrogen to bind to estrogen receptors, thereby inhibiting tumor cell proliferation. Generally, as a patient's disease progresses, dosing should be continued until the lesions completely disappear. With the cooperation of active examination and treatment, if the patient is diagnosed early and is in good physical condition, and treated with fulvestrant, the life expectancy may usually exceed 10 years.
