Early Breast Cancer

Being diagnosed with early breast cancer (EBC) can be difficult, but learning about the disease and how to talk to your doctor can help.

What is early breast cancer?

Early breast cancer is when cancer is found only in the breast or nearby lymph nodes, and has not spread to other parts of the body.

approximately 70% of women with breast cancer have HR+ HER2-

There are different subtypes of breast cancer, based on whether hormone receptors, such as estrogen receptors, or other proteins are involved in how the cancer divides and grows. The most common type is HR+, HER2– breast cancer, which makes up approximately 70% of all breast cancers.

Understanding your early breast cancer diagnosis and prognosis

After being diagnosed with early breast cancer, your doctor may talk to you about a variety of risk factors. These risk factors may impact the prognosis, or course of the disease, and the likelihood of your breast cancer returning. They also inform which treatments may be most helpful. Risk factors can include:

  • Tumor size
  • Lymph node involvement, or whether the cancer has spread from the breast to the nearby lymph nodes
  • Tumor grade, refers to the degree to which the cells in the breast tumor look like normal cells vs cancer cells
  • How fast the tumor is growing

Along with hormone receptor status and HER2 status, these disease factors help to determine the best path forward for treatment. They are also used to help understand the risk of the breast cancer recurring, or coming back again, after or during treatment.

What does it mean if my breast cancer has spread to the lymph nodes?

Lymph nodes are structures that contain immune cells and are part of what is called the lymphatic system. Lymph node involvement, or lymph node-positive breast cancer, means the cancer has spread to the lymph nodes in nearby areas, like the underarm.

Nodal involvement is the first indication that the cancer is moving beyond the original tumor in the breast. Early breast cancer that is node-positive is considered to have a higher risk of recurrence.

What is Ki-67 and how does it relate to breast cancer?

Ki-67 (pronounced “key sixty-seven”) is a type of protein found in cells that are growing and dividing. For people with breast cancer, Ki-67 is used as a biomarker, or indicator, to help determine how quickly the tumor is growing.

How does my doctor test for Ki-67?

To test for Ki-67,* your doctor may send a sample of previously biopsied breast cancer tissue to a lab for analysis. You'll receive the results in your pathology report, which will show what percentage of cancer cells express Ki-67. In the monarchE study, Ki-67 levels ≥20% indicated 'high' Ki-67. If levels of Ki-67 are high, that means cancer cells are quickly dividing and creating new cells.

What happens if my Ki-67 levels are high?

Because not all early breast cancer is the same, your doctor may use Ki-67 along with other information to help determine the likelihood of your cancer returning, and which treatments may work best to reduce the risk of recurrence.

*This is different than an Oncotype DX test, which is a genomic test that analyzes a sample of a cancer tumor to determine how active multiple genes are.

Facts about breast cancer

1 in 8 U.S. women will develop breast cancer

Breast cancer is the most common cancer among women worldwide. About 1 in 8 U.S. women will develop breast cancer over the course of her lifetime

both men and women can be diagnosed with breast cancer

Men and women of all ages can be diagnosed with breast cancer

1 in 3 women are at risk for breast cancer recurrence

1 in 3 women with early breast cancer may experience a cancer recurrence

lymph node involvement, tumor size and many other factors impact the risk of breast cancer

Lymph node involvement, tumor size, and many other factors can impact the risk of recurrence in HR+, HER2– breast cancer

Node-positive breast cancer has a greater chance of recurrence

Breast cancer with nodal involvement, or node-positive, is considered high risk, meaning the chance of recurrence can be even greater

approximately 70% of women with breast cancer have HR+ HER2-

Approximately 70% of all breast cancers are the subtype HR+, HER2–

Early breast cancer treatment options

Treatment involves removing the breast tumor from your body and providing therapy to prevent the cancer from coming back. Treatment for early breast cancer usually involves a combination of surgery, radiation therapy, and systemic therapies, such as chemotherapy and hormone therapy.

Early breast cancer treatment

Surgery

Surgery is often the first form of treatment for early breast cancer. It can include a mastectomy—a procedure to remove the entire breast—or a lumpectomy to remove only the tumor. The type of treatment given after surgery depends on the characteristics related to the tumor and disease, such as:

  • Tumor size
  • Extent of nodal involvement (ie, number of lymph nodes involved)
  • Tumor characteristics (Hormone receptor status, HER2 status, and expression of certain other genes, like Ki-67)

Treatment that is given following surgery is called adjuvant therapy. Many patients who receive Verzenio in the early breast cancer setting will have received therapy before surgery (neoadjuvant therapy), such as chemotherapy, because their cancer has certain high risk characteristics.

Chemotherapy and radiation

Chemotherapy can be given either before surgery (neoadjuvant) or after surgery (adjuvant). Chemotherapy can help lower the risk of the cancer returning, by killing residual or leftover cancer cells that may be circulating in the body. Chemotherapy is considered a systemic therapy because it travels throughout the body and affects cells beyond the breast.

Radiation is generally given after surgery and chemotherapy, and uses targeted beams of intense energy, such as high-energy x-rays, to kill cancer left in or around the breast or nearby lymph nodes.

Hormone therapy and other targeted therapies

In HR+, HER2– breast cancer, the hormone estrogen can act like fuel to any remaining cancer cells, helping them to divide and grow. Following surgery, people with HR+, HER2–, early breast cancer may continue treatment with hormone therapy, which targets and blocks hormones like estrogen to help prevent cancer cells from growing and spreading. Hormone therapy may also be referred to as endocrine therapy.

Like chemotherapy, the goal of adjuvant hormone therapy is also to help prevent or lower the risk of recurrence.

Partnering with your doctor

Asking the right questions will help you and your doctor determine the best treatments to reduce your risk of recurrence.

Here are some questions to think about asking your doctor:

  • Can you recommend additional resources that would help educate me about my disease and treatment?
  • Does my early breast cancer have a high risk of recurrence (meaning a higher likelihood of coming back)? If so, what risk factors do I have?
  • What are my options for treating my HR+, HER2– breast cancer with nodal involvement?
  • What treatment options are available to reduce risk of recurrence after surgery, chemotherapy, and/or radiation?
  • Is Verzenio right for me in combination with my hormone therapy?
  • How is Verzenio taken?
  • If Verzenio is right for me, what can I expect during treatment?
  • What are the potential side effects with Verzenio?
  • How will this treatment affect my quality of life?
  • Do you know of any resources to help with financial support for Verzenio?
