For instance, doctors treat many HER2-positive cancers with the medicine trastuzumab (Herceptin), which attaches to extra HER2 proteins and stops cancer growth. Experts recommend that all people with invasive breast cancer be tested for HER2.
What does HR positive mean on a breast cancer report?
What HR-positive means HR is short for hormone receptor. Breast tumors are tested for both estrogen receptors (ER) and progesterone receptors (PR). Each status appears separately on your pathology report.
Which invasive breast cancers should be tested for hormone receptors?
All invasive breast cancers should be tested for both of these hormone receptors either on the biopsy sample or when the tumor is removed with surgery. About 7 of 10 breast cancers have at least one of these receptors.
Should I get genetic testing for breast cancer?
Usually, genetic testing is recommended if you have: A personal history of breast cancer and meet certain criteria (related to age of diagnosis, type of cancer, presence of certain other cancers or cancer in both breasts, ancestry, and family health history)
How common is breast cancer with both hormone receptors?
All invasive breast cancers should be tested for both of these hormone receptors either on the biopsy sample or when the tumor is removed with surgery. About 2 of 3 breast cancers have at least one of these receptors. This percentage is higher in older women than in younger women.
Is it better to be HR positive or negative?
What is the survival rate for HR positive breast cancers? The survival rate for breast cancers are excellent if the cancer is detected early, and in general HR positive cancers grow slower and have a better prognosis. Overall, breast cancers that are both HR positive and HER2 negative have the best outcomes.
What percent of breast cancer is HR+?
HR-positive breast cancer treatments About 74 percent of all breast cancers are both HR-positive and HER2-negative. Breast cancer that starts in the luminal cells that line the mammary ducts is called luminal A breast cancer.
What does it mean to be HR positive?
A breast cancer is classified as HR-positive if its cells have receptors for the hormones estrogen and progesterone, which suggests the cancer cells receive signals from these hormones that promote their growth. It also means your treatment can include drugs designed to affect hormone production.
Is HR positive breast cancer genetic?
HER2-positive breast cancer is not hereditary, but some other types of gene mutations related to breast cancer are inherited. Genetic testing can tell you if you have any of the mutations currently known to increase risk for breast cancer or other cancers.
What is the deadliest form 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.
Which type of breast cancer has the best prognosis?
Grade 1 has the best prognosis. Some breast cancers need your body’s natural hormones estrogen (ER) and progesterone (PR) to grow. These cancer cells have proteins on the outside of their walls called hormone receptors.
Is it better to have HER2-positive or negative?
Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein.
Is invasive ductal carcinoma aggressive?
The five-year survival rate for localized invasive ductal carcinoma is high — nearly 100% when treated early on. If the cancer has spread to other tissues in the region, the five-year survival rate is 86%. If the cancer has metastasized to distant areas of your body, the five-year survival rate is 28%.
Is it better to be HER2-positive or triple negative?
Conclusions: The triple negative subtype has the worst survival regardless of stage. HER2-positive cancers are heterogeneous and not all have poor survival. ER and PR must be considered. ER status appears to influence 5-year survival more than HER2 status.
Is ER PR positive a good thing?
Hormone Receptor-Positive Breast Cancer If your breast cancer has a significant number of receptors for either estrogen or progesterone, it’s considered hormone-receptor positive. Tumors that are ER/PR-positive are much more likely to respond to hormone therapy than tumors that are ER/PR-negative.
Does breast cancer run on mom or dad’s side?
Having a first-degree relative (mother, sister, or daughter) with breast cancer almost doubles a woman’s risk. Having 2 first-degree relatives increases her risk by about 3-fold. Women with a father or brother who has had breast cancer also have a higher risk of breast cancer.
Can you still get breast cancer without the BRCA gene?
Genetic testing gives people the chance to learn if their breast cancer or family history of breast cancer is due to an inherited gene mutation. Most women who get breast cancer don’t have a BRCA1 or BRCA2 (BRCA1/2) inherited gene mutation.
Is HR+ the same as ER+ in breast cancer?
Breast cancer cells that have receptors for either hormone are considered hormone receptor-positive (HR+), or just hormone-positive. Breast tumors may be positive for estrogen receptors (ER+), progesterone receptors (PR+) or both (ER/PR+). About 80 percent of all HR+ breast cancers are ER+ or ER/PR+.
How common is estrogen receptor positive breast cancer?
About 80% of all breast cancers are “ER-positive.” That means the cancer cells grow in response to the hormone estrogen. About 65% of these are also “PR-positive.” They grow in response to another hormone, progesterone.
How common is HER2 breast cancer?
All new breast cancers are tested for an excess of human epidermal growth factor receptor 2 (HER2). About one out of every five breast cancers have too many HER2 receptors.
What percentage of breast cancers are triple negative?
Triple-negative breast cancer accounts for about 10% to 20% of all breast cancer cases. Every cancer diagnosis is unique, but in general, triple-negative breast cancer is a more aggressive type of tumor with a faster growth rate, higher risk of metastasis and recurrence risk.

Test results will give you your hormone receptor status. It will say a tumor is hormone receptor-positive if at least 1% of the cells tested have estrogen and/ or progesterone receptors. Otherwise, the test will say the tumor is hormone receptor-negative.
What hormones are responsible for cancer growth?
When the hormones estrogen and progesterone attach to these receptors, they fuel the cancer growth. Cancers are called hormone receptor-positive or hormone receptor-negative based on whether or not they have these receptors (proteins). Knowing the hormone receptor status is important in deciding treatment options.
Why are triple negative breast cancers more common?
Triple-negative breast cancer cells don’t have estrogen or progesterone receptors and also don’t make any or too much of the protein called HER2. These cancers tend to be more common in women younger than 40 years of age, who are Black, or who have a mutation in the BRCA1 gene. Triple-negative breast cancers grow and spread faster than most other types of breast cancer. Because the cancer cells don’t have hormone receptors, hormone therapy is not helpful in treating these cancers. And because they don’t have too much HER2, drugs that target HER2 aren’t helpful, either. Chemotherapy can still be useful. See Triple-negative Breast Cancer to learn more.
