First off Welcome to Healing Well Chronic Pain Forum! I am sorry that you had to come here with pain but I am glad you found us, and I think after to get to know everyone here you will be glad you found us too!
I am having a little difficulity understanding why you wouldn't want to tell you pain Doctor about
your cancer in your right Kidney? He is your Doctor and he definitely needs to know about
this, if he is expected to adequately treat you for pain, how do you expect him to do that without knowing your complete condition?. Not just that, but some medications can adveserely affect your kidneys, and with having cancer in one of them, it is of the up most importance, that he knows about
this ASAP!, He might need to change or modify your pain meds. I don't understand why you would think he would cut you off of your treatment, if anything I would suggest to you that he would probably want to enhance your treatrment even more, as Cancer in its self can be extremely painfull!. In any
event your normal doctor will probably notify your pain doctor anyway or at least he should! To answer your question, YES you most DEFINITELY would be endangering your condition by not telling him ( your pain doctor) of your condition! So Please do so ASAP! Again I welcome you to the forum, !
Good Luck to You
