@babs1956, welcome to "the new normal" -- a phrase I detest in general, but in the case of our bloodwork, it's true. On Tagrisso, we'll have low red blood cell count, white blood cell count, low platelet count, low platelet volume, and low lymphocyte count (a type of white blood cell.) It's utterly normal on Tagrisso.

Also, some of us have trouble with splitting nails. Early on, I'd swear I split a nail while wearing gloves. I now take 20 mg of Biotin daily to strengthen my nails. I cleared it with my oncologist, who first assured me Biotin doesn't interact with anything else I'm taking. You should check with your oncologist before adding any meds. Now, my worst problem is that my hair and nails are growing like weeds!
