Pituitary tumors are classified according to the size of the tumor. If the diameter of the tumor is larger than one centimeter, we call it a pituitary macroadenoma, and if it is smaller than one centimeter, we call it a microadenoma. Surgery is usually recommended for macroadenomas because the tumor will continue to grow and press on the optic nerve, causing vision problems, and taking bromocriptine for a long period of time will make the tumor harden and make it more difficult to operate on in the future. Surgery is the only cure for pituitary tumors at this time, and all other treatments are control and palliative! Microadenomas can be treated conservatively with medication. Pituitary tumors grow slowly and can be treated with long-term medication to regulate the hormones in the body to normal so that there is a certain chance of getting pregnant.
