Can't be on biologics after cancer treatment, what now?

So I contacted my rheumatologist today for a telamed appointment and let her know that I had been diagnosed with cancer which has now been treated because I haven't talk to her since January.. And then she informed me that I'm not supposed to be on a biologic if I've had cancer. So she's gonna talk with her higher up and call me back with a decision but I'm kind of freaking out because I know what life was like before biologics and I was in so much pain. So far I've had the mentality of quality over quantity of life but they may take away that option. Has anyone else been in the situation where they were told they were not allowed to be on biologics and what do they do now?
