Should I get rid of rooster in quarantine with suspected canker?? Once healed will he infect flock?

I have previously posted regarding a new rooster to my flock who is in quarantine.

After 10 days a bump appeared and I suspect it is Canker and I just began treatment with Metronidazole and betadine 3 days ago. I am coming up on 4 weeks quarantine and I understand that they are carriers after successful treatment.
What does this mean for my flock if I decide to integrate him?. He is very cool, and I have grown very attached to him, but I don``t want to put anyone at risk. The seller says she will take him back if I am worried. What should I do???
