Hey @onemargie.
I had a blood test before my 3 and 6 month check up after chemo but none from him since. My gp did order one last month due to the weight loss issue but everything was fine. Onc says we'll do hormone level checking after 2yrs on Tamoxifen (god help me) but other than that, nope. He's also not big on too many CT's and neither is my gp (too much added radiation apparently) although they would refer me if I really wanted them. I had mri and bone scan at the 12 month mark and all good. No one seems too worried about the bloods so neither will I.
