I had an op and radiotherapy for early grade 1 breast cancer which finished in December 21. A week before my radiotherapy my eyelid dropped suddenly amd have had blurred/double vision since. Got sent to ED for usual checks for stroke including CT scan, then referred to opthalmology for further checks. Now being sent for MRI for both head & orbit as they said many of the causes related to Breast cancer. I explained couldn't be the case as I was very low risk amd only stage 1 but has now got me concerned. Has anyone else had this? I'm.usally one who plays everything down.
