Thanks for responding. My options are somewhat limited for oncologists in my area, but my doctor seems to have an excellent reputation and is very thorough.

From what I can tell, a few things might be prompting her to do the biopsy--the petechiae and weird rashes I've been getting since around the time I initially got bloodwork done, as well as anemia which has since resolved, and some bone joint pain, which hasn't been bad lately but was excruciating a few months ago (a big part of the reason I went to my GP in the first place). Perhaps she wants to rule out other infections or abnormalities?

The skin stuff in particular has just been weirding me out. I do have an appt. with a dermatologist (as my doctor recommended) next week. I do worry about something like leukemia cutis or something, but I'm still just trying to work through everything. If the biopsy will help to clarify anything, I have no problem having one.
