Cognitive impairment

Hi I was diagnosed with breast cancer last January, had surgery, 6 rounds of chemo & radiotherapy. Got the all clear. Ive been on tamoxifen since last August. Been having some problems with mixing up numbers, saying the wrong word & memory. This has affected me at work as I work in retail. Was wondering if anyone else was suffering the same symptoms?

Omg Mirkwood42 you are not going to believe this but I booked an appointment to see my GP today in case it was early stage of dimension, it just feels like Chemo brain but I finished chemo May this year ??.  Pleased I am not on my own . Xxxx??
