It's possible to have different types of breast cancer in each breast. Your situation involves:

Right breast: Hormone receptor-positive (ER/PR+) and HER2-negative breast cancer, which means these cancer cells contain estrogen and progesterone receptors but not excess HER2 protein.

Left breast: Triple-negative breast Show Full Answer

It's possible to have different types of breast cancer in each breast. Your situation involves:

Right breast: Hormone receptor-positive (ER/PR+) and HER2-negative breast cancer, which means these cancer cells contain estrogen and progesterone receptors but not excess HER2 protein.

Left breast: Triple-negative breast cancer (TNBC), meaning these cancer cells lack all three receptors (ER, PR, and HER2). Each type has different characteristics and treatment approaches:

- ER/PR+ cancers typically respond well to hormone therapy since they rely on hormones to grow
- Triple-negative breast cancer usually requires more aggressive treatment, typically including chemotherapy, surgery, and radiation therapy

Working closely with your healthcare team is important as they'll need to develop a treatment plan that addresses both types of breast cancer effectively.
