A diagnosis of stage 4 breast cancer, also referred to as metastatic breast cancer, can feel triggering and overwhelming. At this stage, the cancer has already spread from other breasts and nearby lymph nodes to other parts of the body, such as bone, liver, lungs, or brain. If you or any loved ones of yours are diagnosed with this stage of cancer, then one of the immediate concerns for patients and their families is the survival rate. Additionally, life expectancy of the patients and how treatments improve survival and quality of life.

In this blog, we’ll discover more about survival and the factors that influence it, along with some tips for these cancer patients!

What is stage 4 breast cancer?

Stage 4 breast cancer, also known as metastatic breast cancer, is the most advanced stage, where the cancer has spread from the breast and nearby lymph nodes to distant parts of the organ and body, most commonly the bones, liver, lungs, and brain. These conditions are not curable; some advanced treatments for this stage 4 cancer focus on managing the symptoms and signs of these cancers, improving the overall quality of life, and extending the survival and life expectancy of patients.

Key characteristics of metastatic breast cancer

  • Metastasis: This is the spread of cancer from its primary site, the breast, into other organs and distant body parts, which often involves the lymph nodes in the process. 
  • Advanced stage: This is the most advanced stage of breast cancer. 
  • Common site of cancer spread: The most frequent sites of these cancers are bones, liver, lungs, and brain.

What is stage 4 breast cancer survival rate?

According to the American Cancer Society, the 5-year relative survival rate for Stage 4 breast cancer is approximately 32%. These data signifies that approximately 32% of people diagnosed with these distant breast cancers will still be alive five years after the cancer diagnosis. On a simple note, 32 patients out of 100 patients diagnosed with these metastatic cancers are expected to live at least 5 years after the initial diagnosis.

However, it’s essential to understand that all these statistical data are based on many patients and may not reflect any current treatment advances. Relative survival often compares patients with these types of cancers to the general public.

Many patients with stage 4 breast cancer live longer than five years, especially with new cancer treatment options.

How advanced treatments are changing the treatment outlook

Metastatic Breast cancer survival rates will steadily improve due to some advanced cancer treatments. 

Here are some treatments options may include:

Targeted therapies

CDK 4/6 inhibitors: Some of the drugs, like ribociclib, palbociclib, and abemaciclib, are powerful treatment options for hormone receptor-positive (HR+) and HER2-negative metastatic breast cancer by slowing cancer growth. 

HER2- targeted therapies: These therapies are used for HER2- positive breast cancers, drugs that target the HER2 protein are essential for controlling the disease. 

Immunotherapy

Immunotherapy uses the body’s own immune system to fight against different types of cancer. It uses drugs like atezolizumab and pembrolizumab and is approved for several types of metastatic triple-negative breast cancers that are PD-L1 negative.

New chemotherapy combinations 

Synergistic effects: New combinations of chemotherapy treatments are used to improve efficacy and reduce side effects, offering new options where traditional treatments have limited benefits. 

Personalized medicines based on genetic profiling 

All of these advancements help cancer patients who are living with stage 4, which helps to improve the quality of life. The overall result of these advanced treatments is that many people with these cancers now live significantly longer, with the disease treated more like a chronic condition.

The increased effectiveness and precision of modern treatments often leads to few severe side effects and longer chemotherapy-free intervals, which greatly improves a patient’s overall quality of life.

How long do you live with this stage 4 breast cancer?

Many studies suggest that metastatic cancer is not always the same for everyone who has been diagnosed with it. The symptoms of stage 4 cancer patients mainly depend on the degree or extent of cancer that has spread in your body. 

Here are some of the factors that can affect the life expectancy of these cancers. 

  • Patient’s age
  • Individual health conditions
  • Hormone receptors and HER2 receptors on cells with cancer
  • The size of the tumor
  • The types of tissue that the cancer has affected

Living with metastatic breast cancer

Patients with metastatic cancers are now living for many years by controlling their disease with certain treatments and lifestyle adjustments. Some patients might refer to this as a chronic health condition, but it's not curable but manageable with many treatments. 

Many studies suggest treatments and lifestyle adjustments that allow these patients to live for years. It helps to control the cancer and helps to maintain an improved quality of life, while the cancer itself cannot be removed completely.

Tips for stage 4 breast cancer patients

Here are some top tips for stage 4 cancer patients, including:

  • Build a cancer care team that includes specialized oncologists, palliative care specialists, and mental health support. 
  • Stay active during this time; if possible, include light exercise, a balanced and nutritious diet, and enough rest and sleep.
  • Join cancer support groups, like online or local cancer support groups, to connect with others with same stage cancer.
