TIRAD 4 and worried about thyroid cancer

I'm not even sure this is the right group for me because it's not confirmed i have Thyroid cancer - but i'm not sure where else to post. Anyway, i had a neck ultrasound done about a week ago for an unrelated issue and an incidental finding was several nodules on my thyroid, so it was recommended i have another ultrasound of just my thyroid. I got those results back this morning - 4 nodules total, two on each lobe, 1 solid one on each lobe and a colloidal cyst on each lobe, only one of the solid ones was described as "concerning" and i was given TIRAD of 4 - it is 1.1 cm x 1.1 cm x 1 cm - the recommendation is to wait a year and do another ultrasound. I know that a TIRAD of 4 means that there were some features that are concerning for malignancy. I do understand that most thyroid cancers are slow growing and metastasis may be rare, so i guess that's why they are ok waiting a year? MY understanding is that if my nodule was 1.5 cm instead of 1.1, i'd be getting a biopsy. I have an appointment with my doctor on tuesday. Is it reasonable to ask for a second opinion? I should also note that I have type 2 diabetes and i'm being monitored for a breast lesion that was BIRAD of 3 - i also was adopted so i don't know all of my family history. I'm just wondering if i should ask my doctor to be referred to an endocrinologist? I think if i spoke to a specialist who is familiar with these types of things and aware of my risk factors, i'd feel better waiting a year if they agreed with that recommendation. Thoughts? I know Thyroid cancer is very treatable but i don't like the thought of something that is potentially malignant staying in my body for a year. thanks
