Thanks. Actually, after I wrote you, I realized they are online on my computer. Duh! I can't understand the medical shorthand. I'll add markers to my list for my appt. next month. I like and trust the oncologist I'm seeing, but it can't hurt to ask him. I thought I had asked about markers but this disease is very challenging and I don't remember everything he says. And I don't take very good notes. Thanks for the heads up.
