I'm sorry I don't have that info in front of me atm. I get two blood tests done every 6 months. They are supposed to show presence or absence of enzyme changes related to the cancer and other data bits like vit D, which I was low on. That's important for your bone health. I have the folder in my car downstairs. I will post or reply more specifically when they're in hand. My specialist is also going to order a bone scan every year. I had my first one and it was fine, but that was a baseline test. He will monitor any changes. I'm still not sold on the med. I have two pages of questions to ask him next month. I do not like the side effects at all. I have high anxiety most of the time. Committing to the med is a daily thing with me.
