I had a biopsy on my thyroid two and a half years ago. Apologies for not replying sooner; I only just saw this. I am in Ireland, so might be different over here, but my feeling is that if there were bad news, they would be in touch with you a lot sooner than 5 weeks after the biopsy. They would also likely want to see you face-to-face, though of course, covid has had an impact on this.

In my case, I had an appointment for a week after the biopsy. This was made before they knew what the results were going to be, but even with that, I got a call two days before my appointment, looking for the scans from the ultrasound to be sent on to the specialist. That sort of worried me a bit and I was right to be. 

A five week wait for a phone appointment sounds to me like they don't think there is any particular urgency.

I will add though that thyroid cancer is unlikely to present any particular urgency anyway. Even if you do have cancer, and I would think that unlikely - something like 95% of nodules biopsied are benign - the most common types of thyroid cancer have a survival rate that comes close to 100%, especially among "younger" people (under about 50) and it is rare they use anything like chemotherapy or radiotherapy. Worst case scenario is the removal of your thyroid. I was back to work and to my normal life a month later.
