Eligibility Criteria

Age 18+ · All Participants · 31 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Your biopsy results show that you have HER2-positive cancer, which is determined by a score of 3+ on the IHC test or a positive result on the ISH test. The study does not require additional testing to confirm this status.
You have cancer in your breast and/or lymph nodes that is negative for hormone receptors but positive for HER2. If your cancer is positive for both hormone receptors and HER2, you must have cancer in your lymph nodes to qualify for the study. It is not required to have cancer remaining in the breast.
You have breast cancer with a low level of estrogen receptor (1-10%) and no cancer cells in your lymph nodes.
Doctors have determined the presence of hormone receptors using biopsy material. If you have positive estrogen or progesterone receptor status, you may be eligible to participate. If you have negative estrogen and progesterone receptor status, you may not be eligible.
You have been diagnosed with breast cancer that has spread to nearby lymph nodes or tissues and have undergone surgery to remove the tumor, but some cancer is still present. If you have been diagnosed with very early-stage breast cancer, you are not eligible to participate.
If you have breast cancer in both breasts and both tumors are HER2-positive, you may be eligible to participate as long as at least one of them meets the other study criteria. It's also okay if you have more than one tumor in the same breast, as long as the largest one is HER2-positive.
