"Radiographic features "
"Tamoxifen is a non-steroidal selective oestrogen receptor modulator (SERM), which acts as an "anti-oestrogen". It binds to the oestrogen receptor and is used primarily for adjuvant therapy in breast cancer. However, it can also act as a pro-oestrogen agonist in a low oestradiol environment. The agonist properties can affect the endometrium, and does, in half of treated patients."
