Hi all. I went for my latest CT/MRI scans...everything is clear except the new development of a thyroid nodule. My oncologist said he was concerned, that we need to do an ultrasound, but that most thyroid nodules are benign. Should I worry? (Of course I am going to regardless...but....) Has anyone else had an issue? I am still set to begin the ipi trial at Memorial Sloan Kettering on the 20th, so he must not be *that* concerned...right?
