Does a partially calcified thyroid nodule measuring 1cm indicate higher risk for ca? i had stage 2 ov ca at age 26(3yrs ago) does that raise risk too?

Needs evaluation: It's possible, so you need a full evaluation with doctor, lab, ultrasound etc. And should have a thyroid biopsy with an affirma test to evaluate for possible cancer. Your doctor can get you started.

Slightly higher: Papillary thyroid cancer can be calcified, but this ultrasound finding is non-specific. Papillary thyroid ca is very treatable. See an endocrinologist who can do an ultrasound-guided biopsy. There is no known relationship between the ovarian ca.
