At the time of diagnosis, the majority of breast cancers are categorized as estrogen-receptor positive, or hormone sensitive, which means their cancerous cells may need estrogen to grow.

In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn't work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time.

Dutch and U.S. medical researchers have discovered a protein profile that may predict whether a breast cancer patient will be resistant to tamoxifen therapy. Tamoxifen is a widely used and effective drug designed to treat breast cancer.
