Dear lumpyfive ,
First of all I wanted to assure you that this medical case will not affect your immigration by any mean . The reason for that is my personal experience in that regard . I had CA and it has been cured before I made my medicals . I was worried about if they will reject my case as I informed the DMP about my case in full details and he has requested medical report from my oncologist calrifying the status of my case. Everything was submitted as requested and I received request from CHC to submit my PPT for PR stamping . Therefore , you do not need to worry . I discussed this issue with my consultant and he informed me " maybe they will require an extra health insurance while landing to cover any possible excessive treatment cost for your medical case in the future " .
I hope this is helpful and wish you all the luck . God Bless You .
Regards,
Palscorpion
