Can my pituitary tumor be THAT harmful?

Uninsured, but a year ago diagnosed with a pituitary tumor. This has mostly only affected my periods and is probably the sole contributor to the amenorrhea, but what else can I expect? I am 21 and have never had more than 4 or 5 periods. Especially since I am not going to be able to afford to get this fixed any time soon. Should I worry about being able to get pregnant later on? I would love to hear from someone that has had an experience with this kind of problem. THank you

Treatment with medications (drug therapy) may help to block excess hormone secretion and sometimes shrink certain types of pituitary tumors like "Prolactin-producing tumors" (prolactinomas). The drugs bromocriptine (Parlodel) and cabergoline (Dostinex) can treat these types of tumors by decreasing prolactin secretion and often reducing the size of the tumor. These drugs are often so effective in treating these types of tumors that surgery isn't necessary. If you're younger, watchful waiting can also be an option as long as you know the facts and accept the possibility of your tumor changing or growing during the observation period, possibly requiring medical treatment. You and your doctor can weigh the risk of symptoms developing versus treatment intervention. I have taken "Dostinex" for about 12 years with good success.
