Im actually HR positive and HER2 negative. I had breast cancer 1999 and have gone every year to have tumour markers done, in good faith. Only to have found out that here in Ireland they didn’t do CA15/3 as there is a percentage of false negatives. I only found that out because I was diagnosed with stage 4, bones, lung liver. 8 months of Palbociclib and Letzetrol and then it turns out it didn’t work on the liver. A pity as lung is clear and bones stable. So now on Xeloda but like I said, it nearly killed me.
