so my dr just called me....and im scared?

A cyst is not cancer. Cancer is not a cyst. You ARE overly concerned.Take a breath and go to your follow up visit as instructed. You're fine.

I had many nodules on the back of my thyroid. Once the nodules (which turned out to be cysts) became large my doctor wanted them to be biopsied to be sure it was not cancer. My family has thyroid problems so I wasn't surprised. Eventually my thyroid was removed but I wasn't in a rush because my thyroid continued to function normally. I did develop a goiter too. (an enlarged thyroid) Today I take a small amount of synthroid each day and am doing fine. Learn all that you can about your condition. You don't need to panic, but do ask questions.

A cyst is a benign growth. Unless a cyst gets big enough to interfere with other structures in the area, it can stay forever.

Your doc is correct; don't stress over it. From now one, you'll have a thyroid ultrasound to see if it's growing any larger, and unless you complain that you are starting to feel it, you'll just have follow ups as your doc directs.

If it starts to interfere with anything, if it starts causing pain, then it's is a fairly simple surgery to have it removed.

Since you know it's there, good; it can be followed and now it's on your medical history.

You sound suspiciously like dannii_ashton. Are you one in the same? I'm surprised a doctor called you; they almost never call. Usually they have a nurse or office clerk call and they don't usually give info over the phone. They normally have you make an appt. If whoever called you said it's common, don't worry, then don't worry. Thyroid cancers don't run in families; your doctor would know that.

Cysts are really nothing to worry about so I wouldnyt worry if your Dr. felt it was a cancerous growth the would get you back in very quickly and do a biopsy of it, they can get a pretty good idea from the untrasound if its something suspicious so for right now I would just breathe your probably fine
