What Is Triple Negative Breast Cancer


Triple negative breast cancer is a basal like breast cancer. I know that there are at least six types because it was stated at the San Antonio Breast Cancer conference that I attended in December.

Who gets triple negative breast cancer? Susan G. Komen states that 15-20 percent of all breast cancer in the United States are triple negative or basal like. Anyone can get it. Often though it occurs with younger women, African American women, Hispanic/Latina women, and women with a BRCA 1 mutation.

Today I got an e-mail from another women with Triple Negative breast cancer.

This cancer is harder to treat because it is limited. It lacks hormone receptors and hormone inhibitors cannot be used. Herceptin is not used because the tumor is often HER2/neu-negative.

If caught early it can be treated and chemo is used. In fact, chemo works better on this type of cancer than others. There are clinical trials going on all the time. Many of us wish there was more research being done in this area.

Triple negative breast cancer does not have bio-markers.

Triple Negative Breast Cancer is referred to as estrogen receptor-negative (ER-), progesterone receptor negative (PR-) and HER2/neu-negative.

This is a very aggressive type of tumor. It tends to grow fast and is not seen on a mammogram which could be once a year or every other year. It seems to come back compared to other types of breast cancer. I had a friend die of it.
