What could replace tamoxiphen in second 5 years after breast cancer? tamoxiphen caused me ovarian cyst and uterus thickening . thanks

May be Femara (letrozole): Letrozole ( Femara (letrozole) ) also redices estrogen levels , discuss with your oncologist will give you the best advise

Letrozole: Tamoxifen for 5 years followed by Letrozole would be an option. However, technically you are still premenopausal so not an option. Another treatment which is controversial is to have your ovaries removes. There is data on 10 years of tamoxifen now but you may not want to do this. The other option would be observation. Hope this helps.
