I am 67yrs old and have been on Letrozole for about 18 months following a mastectomy for lobular breast cancer in May 2024. A recent blood test has shown my white blood cells are low and now outside the therapeutic range. They have gone from 5.3 pre mastectomy to 4.5 last year and 3.6 now. I am having another blood test in a month's time before any decisions are taken.
Assuming it is the Letrozole behind this, what are my options? I was given the all clear at the time so wondered about the risks of stopping it or moving to an alternative.
I have osteoporosis so have also been worried about the bone density effects of letrozole, but have upped my weight bearing exercises in this regard.
