Hormone receptor-positive (ER+/PR+) breast cancer
Hormone receptor-positive breast cancer
About 80 percent of all breast cancers in New Zealand are hormone receptor-positive.
Hormone receptors are proteins found on breast cells.
They pick up the estrogen or progesterone signals that promote cell growth; including cancer cell growth if they contain the receptors for these hormones. Breast cancer cells with receptors for either hormone are considered hormone receptor-positive (HR+).
Breast tumours may be positive for estrogen receptors (ER+), progesterone receptors (PR+) or both (ER/PR+).
Our expert panel share their experiences with HR+ breast cancer from a patient and clinical perspective.
