What characterizes triple-negative breast cancer?

• A. Positive for estrogen and progesterone receptors
• B. Negative for estrogen receptors, progesterone receptors, and HER2 protein
• C. Positive for HER2 protein only
• D. It has the best prognosis among breast cancer types

Answer: (B)

Triple-negative breast cancer is characterized specifically by the absence of estrogen receptors, progesterone receptors, and the HER2 protein. This means that the cancer does not respond to hormonal therapies that target estrogen or progesterone receptors and does not benefit from therapies aimed at the HER2 protein. This subtype of breast cancer is often more aggressive and can be more challenging to treat, making accurate characterization crucial for appropriate management. Patients with this type may not have the same treatment options available to them compared to those with hormone receptor-positive or HER2-positive cancers, which can be effectively managed with targeted therapies. Understanding the specific characteristics of triple-negative breast cancer is essential for treatment planning and determining prognosis.
