I have been prescribed tamoxifen for breast cancer after a lumpectomy - the doctor did not give me letrozole due to my Dexa scan showing osteopenia although I am 66 yrs old - I have just started tamoxifen but read the side effects and noticed retinal issues - I am worried as I have had 2 retinal tears which resulted in a small detachment - how common are retinal issues with tamoxifen and are there any other drugs that I could switch to that don’t have this side effect ?
