In the United States, it’s estimated that more than 42,000 women will die from breast cancer in 2020.
What treatments are available?
Your treatment plan will probably include a combination of therapies, such as:
Surgery
The size, location, and number of tumors help determine the need for breast-conserving surgery or mastectomy, and whether to remove the lymph nodes.
Radiation
Radiation therapy can target any cancer cells that may remain after surgery. It can also be used to shrink tumors.
Chemotherapy
Chemotherapy is a systemic treatment. Powerful drugs can seek out and destroy cancer cells anywhere in the body. HER2-positive breast cancer generally responds well to chemotherapy.
Targeted treatments
Targeted treatments work to attack a specific type of cancer cell. In the case of HER2-positive breast cancer, these drugs would target cells expressing the HER2 protein.
How many breast cancers are HER2 positive?

On the other hand, those patients who do achieve pCR could be spared additional toxic treatments. "At present, all women with HER2-positive breast cancer receive toxic adjuvant chemotherapy ...
Why is HER2 important?
The importance of HER2 status for survival will depend on how far the cancer has spread. If it’s only in the breast, then it won’t make much difference. Most women in the early stage of the disease do well because a surgeon can remove the tumor.
What is the best treatment for her2+ breast cancer?
A common drug for HER2+ breast cancer is trastuzumab ( Herceptin ), but there are others. Because there are more treatments, women with more advanced HER2+ breast cancers today will on average have better survival rates than those with more advanced HER2- breast cancers. Pagination. 1.

Relative survival rates tell you how likely a person with a certain cancer type is to survive, compared to people who are the same age, race, and sex without that cancer type.
What is the survival rate of cancer?
Survival rates for cancer often show how many people survived for 5 years. It’s usually a percentage. So a 5-year survival rate of 75% means that 75% of people with that diagnosis lived for at least 5 years after the diagnosis.
Does HER2 affect survival?
The chances of survival also depend on your age and general health. The fact that the cancer is positive for HER2 will affect your treatment and survival. Experts consider the HER2+ breast cancer to be more aggressive than some other breast cancers. That means it may grow faster without treatment.
