Does a solid nodule indicate cancer?

What does "solid nodule" mean for a person with thyroid disease?

For years, I've had multiple nodules on my thyroid but they were more cystic. After an ultrasound last week, I still have the multiple nodules but now there is a solid nodule as well. What does this mean? Is it indicative of cancer?

My doctor didn't bother to call me. I signed onto the patient portal at her office and saw the results of my ultrasound about the solid nodule and that she was referring me for a biopsy of it. Why would a doctor post something like THIS, which she should imagine would be scary for the patient, without explaining it? She posted this on May 6th. She should have called me on May 6th or May 7th or May 8th! This is just another item on my list on why I am not happy with this doctor. I am going to be searching for a new doctor.

I've been doing a lot of research and I want my TSH levels down to 2 at the maximum. From what I've read online, TSH levels between 1-2 is when most people feel better. Since my TSH levels are so high, it explains why we had such a hard time conceiving our last child. High TSH levels seem to affect fertility.
