The largest category of breast cancers are hormone receptor (HR) positive. These comprise 55-60% of all breast cancers globally as well as in India. Unlike triple negative breast cancer (TNBC), HR positive breast cancers respond well to personalized treatment with newer drugs and have a high chance of successful treatment and long-term survival even in advanced stages. Hence it is important to get them diagnosed and typed for HR positivity early on and tailor the treatment for each patient.
