Chapter: 5 - Types & Stages

Subchapter: 6 - Triple Negative Breast Cancer

In Subchapter 3.1, “Growth of Cancer”, we discussed the role of receptors in cancer cells. Doctors seek to determine what causes certain types of cancer to progress by identifying its “receptors”. These receptors function like mouths: when open, the cancer cells feed and rapidly grow.

Triple Negative Breast Cancer tumors lack receptors for any of three bodily chemicals: estrogen, progesterone, and the HER2/neu gene. There are still effective treatments for it, such as chemotherapy, but doctors are not sure what stimulates this type of tumor to grow.

Women with a family history of breast cancer, specifically with the BRCA1 or BRCA2 breast gene mutation, are more at risk for developing Triple Negative Breast Cancer.

      I would recommend navigatecancerfoundation.org for excellent answers to questions like this. The nurse I speak with has been an oncology nurse for 29 years and answers are usually back within a day. It is sponsored by LIVESTRONG, no charge to cancer patient. Let us know!

      I know you have to do herceptin, which i did for a year. I also had chemo as I had a very small tumor (0.7cm) that was invasive ductal carcinoma. It depends on the tumor, size and many other factors. Don't let being her2 scare you, my oncologist said herceptin is a miracle drug and being her 2...

      I also had stage 1 cancer, HER2 positive. I had a lumpectomy, chemo and radiation(in that order). I am not sure if HER2 positive patients always are a candidate for chemo, but your doctor will advise you on the best treatment for your situation.

    What if my doctor never mentions the Oncotype test? I am an early stage HER2 positive and had a bilateral mastectomy. Will my chemo will be harsh?

      I had the oncotype DX test but it is my understanding it is not used for all types of breast cancer. I believe it is used specifically for estrogen positive cancers -- I do not think it is used for HER cancers, but your oncologist would know the answer to this.
