Tocilizumab and Breast Biopsy.

Good Afternoon,

I wonder if you can offer me some advice. I am taking Tocilizumab every 4 weeks as hospital infusions and Hydroxychloroquine tablets, both for RA. I have recently been told that I may need to have a biopsy following a breast screening appointment. Is it OK to have the breast biopsy whilst on Tocilizumab? I have read on the leaflet that it should be stopped 4 weeks before am operation but does that apply to biopsies?

Any advice would be much appreciated. Thank you.
