Understanding PR-Negative Breast Cancer
Breast cancer is one of the most common cancers among women, and it can come in many different forms. One type of breast cancer is known as PR-Negative, and it is important to understand the characteristics of this type of cancer in order to make informed decisions about treatment.
What is PR-Negative Breast Cancer?
PR-Negative breast cancer is a type of breast cancer that does not express the protein progesterone receptor (PR). This means that the cancer cells do not respond to the hormone progesterone. This type of breast cancer is also known as “triple-negative” because it does not express the three most common receptors for breast cancer: estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2).
How is PR-Negative Breast Cancer Diagnosed?
In order to diagnose PR-Negative breast cancer, a biopsy is performed to examine the tissue from the tumor. The tissue is then tested for the three receptors mentioned above. If the tissue does not express any of the three receptors, then it is classified as PR-Negative.
What are the Treatment Options for PR-Negative Breast Cancer?
Treatment options for PR-Negative breast cancer will depend on the size and stage of the tumor, as well as the patient’s overall health. Common treatment options include surgery, chemotherapy, radiation, and hormone therapy. The goal of treatment is to remove the tumor and reduce the risk of recurrence.
Are There any Risks Associated with PR-Negative Breast Cancer?
PR-Negative breast cancer can be more aggressive than other types of breast cancer. It is important to discuss any potential risks with your doctor in order to make an informed decision about treatment.
