Yesterday I met with my Medical Oncologist, to go over what I had hoped was a treatment plan for chemo. Turns out I’m a bit of a medical weirdo. One tumor is HER2- and one is HER2+. Both are in my left boob.
My Med. Oncol. is meeting with heads of pathology and radiology to dig into the results and make sure that this is the case. So I have no idea what chemo I will be given or the drug that is to be partnered up.
She did mention that one could be hard on my heart, and that has me concerned, because I am super active and love running and hiking. Running has been my sanity saver for decades, and to think that my heart could not handle any future cardio-craziness, is a hard pill to swallow. I know that chemo will likely knock me on my ass, but I also know that I’m used to pushing through a LOT of physical adversity, and find a way to navigate through. I just had expected yesterday to have more answers than questions with my treatment.
I did some blood labs, and she is scheduling me for a bone scan, echocardiogram, and other tests to get a baseline on the condition of my heart, as well as make sure that no wondering cells have planted a flag in any other parts of my body.
