Do you know your breast cancer type?
In many low and middle income countries, women are diagnosed with breast cancer and begin treatment without fully understanding their cancer subtype or sometimes without having the necessary testing done to determine it.
One of the most important tests after a breast cancer diagnosis is called Immunohistochemistry (IHC).
This test looks at:
✔ ER
✔ PR
✔ HER2
These markers help doctors understand what is driving the cancer and guide treatment decisions.
Not all breast cancers are the same.
Not all treatments work for every type.
An IHC test can help determine the most appropriate treatment pathway and may influence decisions about surgery, chemotherapy, hormone therapy, targeted therapy, and follow up care.
If you have been diagnosed with breast cancer, ask:
• Was an IHC test done?
• What is my ER status?
• What is my PR status?
• What is my HER2 status?
Every woman deserves to know her breast cancer type and have treatment guided by the best available information.
Knowledge is power. Know your type.
