Lactinopituitary tumors can be cured by taking medication. Prolactinopituitary tumor is a kind of functional pituitary adenoma. The tumor will secrete a large amount of abnormal prolactin, causing patients to suffer from menstrual disorders, amenorrhea, breast overflow and infertility. Bromocriptine can cause the prolactin in the body to drop rapidly to normal, causing the tumor to shrink significantly or even disappear completely, so that a cure can be achieved. When the tumor disappears and the lactogen drops to normal, it is necessary to take the lowest dose of the drug for maintenance treatment, otherwise the tumor will easily recur once the drug is stopped. After taking the drug for more than 5 years, experimental drug reduction and discontinuation can be carried out. Some patients can completely stop the drug and the tumor will not come back, but most patients still need to take the drug for life.
