What is metastatic breast cancer?
Metastatic breast cancer (MBC), also known as advanced or stage IV, is breast cancer that has spread beyond the breast to other parts of the body. The common places for breast cancer to spread are the bones, lungs, liver, and brain.
Treatment of metastatic breast cancer depends on several factors, including prior treatment history, menopausal status, HR and HER2 status, and where the cancer has spread.
Facts about metastatic breast cancer

20% to 30% of people diagnosed with early-stage breast cancer will develop metastatic breast cancer

Metastatic breast cancer can occur any number of years after an initial diagnosis of early breast cancer, even after treatment and regular follow-up visits with your doctor

An estimated 155,000 Americans are currently living with metastatic breast cancer

People of all ages, both men and women, can be diagnosed with metastatic breast cancer

About 6% to 10% of metastatic breast cancer patients are diagnosed with MBC as their first breast cancer diagnosis. This is called de novo metastatic breast cancer

There's more than one type of metastatic breast cancer. HR+, HER2– is the most common subtype of metastatic breast cancer, representing roughly 60% of all cases
HER2–=human epidermal growth factor receptor 2-negative; HR+=hormone receptor-positive.
Treatment options for HR+, HER2– metastatic breast cancer

When you're discussing a treatment option for metastatic breast cancer with your doctor, it's important to know that you have various options, but the decision will depend on several patient and tumor factors, such as HR or HER2 status.
Systemic treatment options
Most metastatic breast cancer is treated with systemic therapy. Systemic therapy travels throughout the bloodstream, reaching cancerous cells throughout the body. These treatments affect both cancerous and normal cells. Sometimes different systemic treatments are combined with each other.
Systemic treatments include the following:
- Hormone treatments
- Targeted treatments, such as Verzenio
- Chemotherapy
Local treatment options
Local treatments such as surgery or radiation may be used to help prevent or treat symptoms of metastatic breast cancer.

Caption: Verzenio is a prescription medicine used to treat a type of breast cancer in adults. It is a medicine:
- You can take if you have a type of breast cancer called HR+, HER2– (hormone receptor positive, human epidermal growth factor receptor 2 negative) and the cancer has spread to other parts of the body (metastasized)
- That is given with an aromatase inhibitor as initial endocrine-based therapy. If the cancer has gotten worse after hormone therapy, then Verzenio is given with fulvestrant. If the cancer has gotten worse after both hormone therapy and chemotherapy, then Verzenio is given by itself
It is not known if Verzenio is safe and effective in children.

My name is Karen and in January of 2017, I was diagnosed with breast cancer—stage 4. The diagnosis was shocking, of course, but at the same time I knew that I was going to change my narrative. I was going to research, and I was going to fight. I don't take "No" for an answer. You know, this is New Yok City, you either get down or lay down. You know, I want to stay alive, I think that's the basic answer, is that I want to stay alive.

Karen: You try to shield your loved ones from news like this. It's hard because they are going through it with you. My baby sister, I'm always protecting her. I wanted to let her know that I have a plan. Everything is going to be okay. I just need your help in order to be able to execute that plan. She never lets me just slack off, you know, just “woe is me”. No, she set up a low-impact fitness class today and I'm looking forward to it.

Pamela: Karen, I actually have a little something. "I can't say enough wonderful things about you. While many get to call you friend—I have the only distinction of being able to call you sister. While some people take that role lightly, you have always been there for me and the universe is brighter because of you. You've been my biggest champion, my fighter and my friend. I'm so proud of you and all that you've done. I'm so proud of your warrior spirit. Each time I find myself crying or ungrateful, I think about what you've had to fight for and yet you're still standing. You've always been my protector and I think you're such an inspiration. My girls see you marching down the streets of New York, and they're kind of parting the sidewalk. They are marching directly behind you and they're going 'That's my aunt, she's somebody special.' Your nieces and I are just honored to call you family. We love you."
