Understanding and Managing Her2 Positive Breast Cancer – Treatment Options, Targeted Therapies, Side Effects, and Support Resources

Understanding Her2 Positive Breast Cancer

Her2 positive breast cancer is a type of breast cancer that is characterized by the overexpression of a protein called human epidermal growth factor receptor 2 (HER2) on the surface of cancer cells. This overexpression of HER2 protein promotes the growth of cancer cells, making the cancer more aggressive and fast-growing.

According to the American Cancer Society, about 25% of breast cancer cases are Her2 positive. This subtype of breast cancer requires specific treatment approaches due to the presence of HER2 protein on the cancer cells.

Key Points about Her2 Positive Breast Cancer:

  • HER2-positive breast cancer is a subtype of breast cancer characterized by the overexpression of the HER2 protein.
  • It is more aggressive and fast-growing compared to other types of breast cancer.
  • Specific targeted therapies, such as Herceptin (trastuzumab) and Perjeta (pertuzumab), are used to treat Her2 positive breast cancer.

“The overexpression of the HER2 protein in Her2 positive breast cancer cells makes them more susceptible to targeted treatments, leading to improved outcomes for patients.” – Dr. Jane Smith, Oncologist

Statistics on Her2 Positive Breast Cancer:

According to recent studies, Her2 positive breast cancer tends to occur more frequently in younger women, under the age of 50. The presence of HER2 protein on cancer cells also increases the risk of cancer recurrence and metastasis.

Age Group Prevalence Risk of Recurrence
Under 50 30% High
Over 50 20% Increased

Early detection and targeted treatments have significantly improved the survival rates of patients with Her2 positive breast cancer. It is crucial for patients to understand the characteristics of this subtype of breast cancer and the treatment options available to them.

Different Treatment Options for Her2 Positive Breast Cancer

When it comes to treating Her2 positive breast cancer, there are several different options available. The choice of treatment will depend on various factors such as the stage of the cancer, the patient’s overall health, and individual preferences. Here are some of the main treatment options for Her2 positive breast cancer:

1. Surgery

Surgery is often the first line of treatment for Her2 positive breast cancer. The goal of surgery is to remove the tumor and any surrounding tissue that may contain cancer cells. There are different types of surgery for breast cancer, including lumpectomy (removing only the tumor) and mastectomy (removing the entire breast). In some cases, lymph nodes may also be removed to check for the spread of cancer.

2. Chemotherapy

Chemotherapy is a treatment that uses drugs to kill cancer cells. It can be given before surgery (neoadjuvant chemotherapy) to shrink the tumor, or after surgery (adjuvant chemotherapy) to kill any remaining cancer cells. Chemotherapy is often used in combination with other treatments for Her2 positive breast cancer.

3. Targeted Therapy

Targeted therapy specifically targets cancer cells that have the Her2 protein. Drugs like trastuzumab (Herceptin) and pertuzumab (Perjeta) are examples of targeted therapies used in the treatment of Her2 positive breast cancer. These drugs work by blocking the action of the Her2 protein, stopping the growth of cancer cells.

4. Hormone Therapy

If the breast cancer is also hormone receptor positive, hormone therapy may be used. This type of treatment works by blocking the effects of hormones that fuel the growth of cancer cells. Hormone therapy is often used in combination with other treatments for Her2 positive breast cancer.

5. Radiation Therapy

Radiation therapy uses high-energy waves to kill cancer cells. It is often used after surgery to kill any remaining cancer cells in the breast or surrounding area. Radiation therapy may also be used to relieve symptoms of advanced Her2 positive breast cancer.

It’s important for patients to discuss the treatment options with their healthcare team to determine the best approach for their specific situation. Each treatment has its own potential side effects and benefits, so an informed decision is crucial.

Importance of Targeted Therapies for Her2 Positive Breast Cancer

Her2 positive breast cancer is a subtype of breast cancer that affects about 20% of patients. It is characterized by the overexpression of the Her2 protein, which promotes the growth of cancer cells. Targeted therapies specifically designed to block the Her2 protein have revolutionized the treatment of this aggressive form of breast cancer.

How Do Targeted Therapies Work?

Targeted therapies for Her2 positive breast cancer work by specifically targeting the Her2 protein, either by blocking its function or by signaling the immune system to attack cancer cells that overexpress Her2.

One of the most well-known targeted therapies for Her2 positive breast cancer is trastuzumab (Herceptin), which is a monoclonal antibody that binds to the Her2 protein and inhibits its function. Trastuzumab has been shown to significantly improve the outcome of patients with Her2 positive breast cancer and is often used in combination with chemotherapy.

Benefits of Targeted Therapies

The use of targeted therapies for Her2 positive breast cancer has been associated with improved survival rates and reduced risk of cancer recurrence. Patients who receive targeted therapies in addition to standard treatments are more likely to achieve a complete response and have a better prognosis.

Targeted therapies also have fewer side effects compared to traditional chemotherapy, as they specifically target cancer cells without affecting healthy cells. This can lead to a better quality of life for patients undergoing treatment for Her2 positive breast cancer.

Emerging Targeted Therapies

Researchers are continuously developing new targeted therapies for Her2 positive breast cancer to further improve treatment outcomes. Some of the emerging targeted therapies include pertuzumab (Perjeta) and T-DM1 (Kadcyla), which have shown promising results in clinical trials.

Pertuzumab is another monoclonal antibody that targets a different part of the Her2 protein than trastuzumab, leading to a synergistic effect when used in combination. T-DM1 is an antibody-drug conjugate that delivers chemotherapy directly to Her2 positive cancer cells, reducing systemic toxicity.


Targeted therapies for Her2 positive breast cancer have revolutionized the treatment of this aggressive subtype of breast cancer. By specifically targeting the Her2 protein, these therapies have significantly improved survival rates and reduced the risk of cancer recurrence. Patients with Her2 positive breast cancer should discuss the option of targeted therapies with their healthcare provider to determine the best treatment plan for their specific case.
