New BC diagnosis with history of Rheumatoid arthritis

Is there anybody out there that has both breast cancer and a previous diagnosis of rheumatoid arthritis?

I'm new to this website and I've recently been diagnosed with DCIS Stage 0 grade 3 breast cancer. I'll be going for a lumpectomy this week and have been told by my surgeon that because the cancer was caught in an early stage and it hasn't spread beyond the ducts that I will be needing radiation and hormone therapy. The pathology report showed that I was positive for both estrogen and progesterone receptors and was told that was a good ithing because it could be treated with hormone therapy. The medical oncologist said he would use Anastrazole in his treatment of the hormones even though he mentioned that it could cause joint pain. I've already had RA for several years now and can't imagine having to deal with any increased joint pain due to medication for treating breast cancer. For the past 6 years I've been on Methotrexate and Humira for my RA and when I messaged my rheumatologist letting him know of my new diagnosis he immediately replied that I would have to discontinue the Humira. I'll be see my rheumatologist next month to discuss his plan on how he will go about treating my RA now. I've started researching what having both these conditions might mean for an individual and it doesn't sound too reassuring. In the meantime, I was just wondering if there's anyone out there who has had to deal with these two conditions together at the same time?
