HiErika888
I have been taking Letrozole for a year now - likeCath62 says it’s to give myself the best chance of reducing the likelihood of recurrence. Like you I am taking VitD and calcium (recommended by the oncologist after my bone density scan).
I had blood tests regularly before each infusion right throughout chemo but I also had a benchmark set of tests on completion of treatment carried out by my GP. It varies for everyone but my risk profile prior to breast cancer included a family history of issues (and having Herceptin could exacerbate it) so my GP was prompted to check my heart, vascular and general health through a blood test and it was not triggered by being prescribed Letrozole.
Prior to breast cancer treatment my results were more or less perfect, but this first benchmark showed variances which my oncologist and GP have been monitoring and over the past 12 months the blood tests results improved. My oncologist and GP consider that my focus on appropriate exercise and what I eat (I don’t drink alcohol) has helped but that it probably just took my system a bit longer than others to bounce back to “normal” (for me). We didn’t see a correlation or impact on my bloods when I had a 4 week break from Letrozole (long haul flights).
When I see my oncologist she receives any tests the GP has done.
