That’s tough, dealing with lung cancer and RA! I suggest you see your rheumatologist again and request (firmly) that your oncologist and rheumatologist speak with each other. They may be able to come up with something. Some RA meds are actually also used for cancer treatment. I honestly don’t know if they will be able to come up with a plan to treat both diseases, but it’s worth a try! I Hope for the best for you in your treatment. Jo (moderator)
