I am new here; I have been on a different side for a while. Simply, I ended up with Pancytopenia after 13 rounds of chemo and it continued with a version of the Olaparib pill that i was told was a cousin of Lynparza. This was December of 2021. In Feb i had surgery. I must add I was diagnosed with BRCA2+ in August of 2021. Come June of 2022, I was on Lynparza for 1 year. I was only stage 2, but I was Brca2 and Her2+. Er+/Pr-. My MO doctor felt this was a good choice. 200mg am and pm. 1/3 less than the 29 day pill i had in ecember. All in all, I was on Herceptin/Perjeta infusions for 18 rounds during this time. After each end side effects lessened. Joint aches, and neuropathy. Lynparza is a chemo pill, but no more hair loss. In all, my white cells remain low and platelets too. One great thing, the metal taste is gone.
