Do you need chemo if you are HER2-positive?
Trastuzumab and chemotherapy are even recommended for women with very small, HER2-positive breast cancers. Tumors as small as 0.5 cm often warrant such treatment.
Does HER2-negative mean chemotherapy?
HER2 breast cancers are likely to benefit from chemotherapy and treatment targeted to HER2. Group 4 (basal-like). This type, which is also called triple-negative breast cancer, includes tumors that are ER negative, PR negative and HER2 negative. Basal-like breast cancers are likely to benefit from chemotherapy.
Is it better to be HER2-negative or positive?
HER2-positive cancer tends to be poorer in terms of prognosis than HER2-negative cancer because: It grows faster. It is more likely to spread to the lymph nodes fast. It is at least two times more likely to return than HER2-negative tumors.
What does it mean to be HER2-positive?
HER2 is a growth-promoting protein on the outside of all breast cells. Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than other breast cancers, but are much more likely to respond to treatment with drugs that target the HER2 protein.
Is HER2-positive a death sentence?

How long is chemo for HER2-positive?
Cycles can last anywhere from about two to four weeks, depending on the combination of drugs. Chemotherapy generally lasts about three to six months. The total length of chemotherapy treatment may vary depending on the stage of breast cancer and a number of other factors.
Does HER2-positive run in families?
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.
Can HER2-positive become negative?
Research has shown that some breast cancers that are HER2-positive can become HER2-negative over time.
Is HER2-positive metastatic?
About 20% of breast cancers are HER2-positive. They usually grow quicker than other types of cancer. Metastatic HER2-positive breast cancer has spread beyond the breast to other parts of the body.
Can HER2-negative Be Cured?
When you have HER2-negative advanced (metastatic) breast cancer, treatment usually focuses on managing your disease, not curing the cancer. The goal is to help you live longer and have a better quality of life. This type of cancer is most often treated with systemic therapy.

What cancers can be HER2 positive?
Cancers that may be HER2 positive include breast, bladder, pancreatic, ovarian, and stomach cancers. Also called c-erbB-2 positive and human epidermal growth factor receptor 2 positive.
Can you change HER2 status?
Breast Cancer’s Hormone Receptor and HER2 Status Can Change After Diagnosis. The characteristics of a breast cancer — including hormone receptor status and HER2 status — can change over time. These changes may happen because the cancer cells change themselves or because treatment changes the cells.
