I had only 1 small nodule on thyroid and within a year now have multiple complex cysts and goiter? is it safe two wait 2 months to see endo? concern?

Almost certainly: Hi. You are almost certainly safe waiting 2 months to see the endo. Glands like yours are very unlikely to be cancer. I would assume your primary care doc has checked your thyroid function before referring you, and you've obviously had a thyroid ultrasound. Please bring any data (labs, ultrasound, etc) with you to the endo appointment. Statistically, that thyroid isn't likely to cause trouble.
