A cancer is called estrogen-receptor-positive (ER+) if it has receptors for estrogen. This suggests that the cancer cells, like normal breast cells, may receive signals from estrogen that could promote growth. The cancer is progesterone-receptor-positive (PR+) if it has progesterone receptors. In about 1 of every 5 breast cancers, the cancer cells have a gene mutation that makes an excess of the HER2 protein. HER2-positive breast cancers tend to be more aggressive than other types of breast cancer. They are less likely to be sensitive to hormone therapy, though many people with HER2-positive breast cancer can still benefit from hormone therapy.
