Hi, for the last four sessions of chemotherapy I received EC & pembro. After the third session it was discovered that the pembro has given me Addisons which has basically shut down my bodies ability to produce cortisone. I have since been on 20ml of hydrocortisone every day to substitute what my body should be naturally producing. My oncologist, previous to the last treatment, was suggesting that a course of pembro every 6 weeks for 2 years would be advised to help keep the cancer from returning. In my opinion the Pembro has wrecked my own immune system so to say l am somewhat not on board with this plan is an understatement. Please could you give me your opinion, as any thoughts at this time would be helpful. Thank you.
