Understanding HER2-Negative Breast Cancer: What You Need to Know

Breast cancer is one of the most commonly diagnosed forms of cancer in women. There are many different types of breast cancer, and each type is unique in its own way. One type of breast cancer is known as HER2-negative breast cancer. This type of breast cancer is important to understand and can help you make informed decisions about your health and treatment.

What is HER2-Negative Breast Cancer?

HER2-negative breast cancer is a type of breast cancer that is not fueled by the presence of the HER2 protein. This protein is found on the surface of some breast cancer cells, and it can cause the cancer to grow and spread more quickly. HER2-negative breast cancer does not have the HER2 protein on the surface of the cancer cells, so the cancer is not as aggressive and is typically treated differently than other types of breast cancer. HER2-negative breast cancer may also be accompanied by either ER positive, PR positive,  ER negative, or PR negative receptors.

How is HER2-Negative Breast Cancer Diagnosed?

HER2-negative breast cancer is typically diagnosed through a biopsy. During a biopsy, a sample of tissue is taken from the breast and sent to a lab for testing. The lab will look for the presence of the HER2 protein on the cancer cells. If the HER2 protein is not present, then the cancer is classified as HER2-negative.

What Are the Treatment Options for HER2-Negative Breast Cancer?

The treatment options for HER2-negative breast cancer vary depending on the stage and type of cancer. Generally, the treatment will include a combination of surgery, radiation, and chemotherapy. The goal of these treatments is to remove the cancer and prevent it from spreading.

What Are the Prognosis and Survival Rates for HER2-Negative Breast Cancer?

The prognosis and survival rates for HER2-negative breast cancer depend on the stage and type of cancer. Generally, HER2-negative breast cancer is less aggressive than other types of breast cancer, so the prognosis and survival rates are typically better.
