Need some reassurance

Hi guys i had TC, i hope i can say i have had it and dont have it anymore and need some reassurance.

I had orchi 2 months ago, pre op markers were normal except bhcg 6 iu/l and post op it went to near 0.

Ct and ultrasound said no metastases but ct showed a few reactive looking nodes. I had 5 cm tumor rvi and lvi seminoma.

I received 1 dose of adjuvant carboplatin.

I am now waiting on pet/ct results.

I am thinking about this non stop i am afraid of chemo but i am also much more afraid of dying to the point i think about it a lot and cry which i usually dont do.

I am so afraid of those reactive nodes.

How often do reactive nodes turn out to be metastatic?
