Instead, it groups cancers into localized, regional, and distant stages: The SEER database, however, does not group cancers by AJCC TNM stages (stage 1, stage 2, stage 3, etc.). The SEER database tracks 5-year relative survival rates for breast cancer in the United States, based on how far the cancer has spread. The American Cancer Society relies on information from the Surveillance, Epidemiology, and End Results Program (SEER) database, maintained by the National Cancer Institute (NCI), to provide survival statistics for different types of cancer. For example, if the 5-year relative survival rate for a specific stage of breast cancer is 90%, it means that women who have that cancer are, on average, about 90% as likely as women who don’t have that cancer to live for at least 5 years after being diagnosed.

What is a 5-year relative survival rate?Ī relative survival rate compares women with the same type and stage of breast cancer to women in the overall population. Talk with your doctor about how these numbers may apply to you, as they are familiar with your situation.

These statistics can be confusing and may lead you to have more questions.

Keep in mind that survival rates are estimates and are often based on previous outcomes of large numbers of people who had a specific cancer, but they can’t predict what will happen in any particular person’s case. They can’t tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful. Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time (usually 5 years) after they were diagnosed. The outlook is generally not as good as it is for other types of breast cancer. Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it’s found, and is more likely to come back after treatment than other types of breast cancer. Survival rates for triple-negative breast cancer If the cells do not have estrogen or progesterone receptors (ER or PR), and also do not make any or too much of the HER2 protein, the cancer is considered to be triple-negative breast cancer. Once a breast cancer diagnosis has been made using imaging tests and a biopsy, the cancer cells will be checked for certain proteins. How is triple-negative breast cancer diagnosed? Triple-negative breast cancer can have the same signs and symptoms as other common types of breast cancer.

Signs and symptoms of triple-negative breast cancer TNBC differs from other types of invasive breast cancer in that it tends to grow and spread faster, has fewer treatment options, and tends to have a worse prognosis (outcome). (The cells test 'negative' on all 3 tests.) These cancers tend to be more common in women younger than age 40, who are Black, or who have a BRCA1 mutation. The term triple-negative breast cancer refers to the fact that the cancer cells don’t have estrogen or progesterone receptors (ER or PR) and also don’t make any or too much of the protein called HER2. Triple-negative breast cancer (TNBC) accounts for about 10-15%
