Best answer: Is HER2 positive breast cancer radiation necessary?

Does HER2-positive require radiation?

Treatment for HER2-positive cancer typically begins with chemotherapy to shrink the tumor(s), followed by surgery to remove it. Patients then undergo radiation therapy to knock out any lingering malignant cells.

Is breast cancer radiation always necessary?

Can breast cancer be treated without radiation?

For patients with noninvasive cancer (known as “ductal carcinoma in situ” or DCIS) matters are more complicated. Lumpectomy without radiation works well for many patients. However, there is disagreement on who can be treated safely with just a lumpectomy. This should be discussed in detail with your doctor.

It may be that this lack of radiation therapy after a second lumpectomy partially explains the difference in survival rates. Radiation therapy is not always used after mastectomy.
