The treatment for HER2-positive (HER2+) and HER2-negative (HER2-) breast cancer differs significantly due to the presence or absence of the HER2 protein. Here's a breakdown:

The treatment for HER2-positive (HER2+) and HER2-negative (HER2-) breast cancer differs significantly due to the presence or absence of the HER2 protein. Here's a breakdown:
1. HER2-Positive (HER2+):
- Treated with targeted therapies like trastuzumab (Herceptin) or pertuzumab (Perjeta), which specifically block the HER2 protein.
- May also include chemotherapy, hormone therapy (if hormone receptor-positive), surgery, and radiation.
2. HER2-Negative (HER2-):
- Does not respond to HER2-targeted therapies.
- Treatment focuses on hormone therapy (e.g., tamoxifen or aromatase inhibitors) if hormone receptor-positive, along with surgery, radiation, and possibly chemotherapy.
Since you are estrogen and progesterone receptor-positive (ER+/PR+) with stage 1 invasive ductal carcinoma, your treatment may include hormone therapy to lower recurrence risk and possibly surgery and radiation, depending on your specific case.
