Triple-negative breast cancer is a kind of breast cancer that does not have any of the receptors that are commonly found in breast cancer. Think of cancer cells as a house. The front door may have three kinds of locks, called receptors —. If your cancer has any of these three locks, doctors have a few keys like hormone therapy or other drugs they can use to help destroy the cancer cells. So doctors have fewer keys for treatment.
Breast cancer: Symptoms, causes, and treatment
It is fairly common for people to be diagnosed with stage 2 breast cancer. Stage 2 tumors are usually between 2 and 5 centimeters cm in diameter 1 to 2. Radiation therapy is given following a lumpectomy, but may or may not be needed after a mastectomy. If the tumor is estrogen receptor-positive, hormonal therapy is usually given for five to 10 years, and for those who are postmenopausal, bisphosphonate therapy may be recommended as well to reduce the risk of recurrence. Stage 2 breast cancer is considered "invasive," meaning that cancer cells have broken out of the ducts or lobules of the breast. This is not the same as metastatic stage 4 breast cancer. Cancers are scored and divided into stages by something called the TNM system.
An Overview of Stage 2 Breast Cancer
Not all breast cancers are the same. Understand what type of breast cancer you have and how it differs from other types of breast cancer. Once you've been diagnosed with breast cancer, your doctor will review your pathology report and the results of any imaging tests to understand the specifics of your tumor. Using a tissue sample from your breast biopsy or using your tumor if you've already undergone surgery, your medical team determines your breast cancer type.
Hearing you have stage 3 breast cancer can bring many questions — about your diagnosis, survival, treatments, and more. First, stage 3 breast cancer means your cancer has spread beyond the tumor and has possibly gone to lymph nodes and muscle, but has not spread to nearby organs. Doctors divide stage 3 into more specific categories 3A, 3B, and 3C and the cancer subtype, meaning which type of breast cancer you have. The breast cancer type describes how a cancer grows and what treatments are likely to be most effective. Stage 3 breast cancer is considered advanced cancer.
