Can Cancer Cause Addison S Disease?

hi ive got late stage breast cancer and addisons. diagnosed cancer in 2004. reacured 2008. i was always sick but many doctors didnt figure it out. here is my question. inoticed that the symtoms of addison were worse when cancer was growin. this includes right before i was diagnosed with the cancer, but when i started the chemo i felt better. the last 2 years ive been on lots of chemo, and been very sick, finally figured out my old doctor gave cortisone with the chemo. so tested for addisons. so can addisons detect or be influenced by other cancers, would this be considered stress even if you didnt know about it
