Description
Why It’s Done:
The IHC – Breast Cancer Prognosis Basic Panel is performed to:
• Determine hormone receptor status of breast cancer (ER and/or PR positive or negative).
• Guide treatment decisions—patients with ER/PR-positive tumors often benefit from hormone therapy such as tamoxifen or aromatase inhibitors.
• Predict the behavior and prognosis of the cancer; hormone receptor-positive cancers tend to grow more slowly and have a better prognosis.
• Help stratify patients for personalized treatment plans.
Preparation:
• No special preparation is required for the test itself.
• It is performed on a breast tissue sample, typically obtained during a biopsy or surgery.
• Pre-biopsy instructions should be followed if applicable (e.g., fasting, medication guidelines).
• Inform your doctor about any medications or health conditions, especially if you are scheduled for a biopsy procedure.
